Background

[0001] Moving some aspects of workload execution, such as artificial intelligence modules, from the cloud to edge devices can improve workload execution speed and can allow for execution of a workload without a connection to the cloud. However, the workload may not be as secure on the edge device as on the cloud.

Summary

[0002] In at least one implementation, the disclosed technology provides for packaging a secure cloud workload at a workload provisioning service. A unique device identifier is received from an edge device. The unique identifier is associated with the edge device. A unique packaging key is cryptographically generated based on the received unique device identifier, a unique workload identifier corresponding to a secure cloud workload to be executed on the edge device, and a nonce. The secure cloud workload is encrypted to generate a packaged secure cloud workload using the cryptographically generated unique packaging key. The encrypted secure cloud workload is transmitted to the edge device. The edge device is capable of independently cryptographically generating the unique packaging key using the unique device identifier, the unique workload identifier, and the nonce. The edge device is also capable of decrypting the packaged secure cloud workload using the generated unique packaging key cryptographically generated by the edge device.

Detailed Descriptions

[0011] When a workload is executed on an edge device instead of in the cloud, the execution of the workload may be faster, partially because an internet connection may not be required. However, it is often less secure to execute a workload on an edge device, because the edge device may be more susceptible to corruption or unauthorized entry. Using a unique packaging key that is separately generated at both a workload provisioning service and at the edge device makes execution of workloads on edge devices more secure.

[0012] FIG. 1 illustrates an example workload provisioning service hardware 102 in communication with edge devices 106, 108, and 110 through a communications network 112. Generally, the workload provisioning service hardware 102 is comprised of one or more workload provisioning servers and includes a datastore 118 including workloads for various edge devices, such as the edge devices 106, 108, and 110. A workload may include any discrete task to be performed by an edge device. An edge device may be a device connected to the internet of things (IoT).

[0013] The workload provisioning service hardware 102 may send workloads to any of the edge devices 106, 108, or 110 through the communications network 112. Some workloads may include sensitive, confidential, or otherwise restricted data that may be encrypted before being sent over the communications network 112. The workload provisioning service hardware 102 may encrypt and package the workload before sending it to an edge device (i.e., the edge device 106. The workload is encrypted using a unique packaging key unique to the workload and the device. The unique packaging key is generated by the workload provisioning service hardware 102. The encrypted workload is communicated to the edge device 106. The edge device 106 separately generates the unique packaging key to decrypt the workload before execution of the workload.

[0014] The edge device 106 communicates a unique device identifier 114 to the workload provisioning service hardware 102 using the communications network 112. The edge device 106 may communicate the unique device identifier 114 in response to a request from the workload provisioning service hardware 102 or as part of a request from the edge device 106 to the workload provisioning service hardware 102. The unique device identifier 114 may be a unique string of characters corresponding to the edge device 106.

[0015] The workload provisioning service hardware 102 uses the unique device identifier 114 along with a unique workload identifier and a nonce to generate the unique packaging key. The unique workload identifier corresponds to the workload. The nonce may be generated by the workload provisioning service hardware 102 or may be requested by the workload provisioning service. The workload provisioning service hardware 102 uses the unique packaging key to encrypt the secure cloud workload to generate a packaged secure cloud workload 116.

[0016] FIG. 2 illustrates an example workload provisioning service 202 delivering an encrypted secure cloud workload 216 to an edge device 206. The workload

provisioning service 202 includes at least a network communications interface 218, a unique packaging key generator 220, a workload encryptor 222, and a datastore 232.

[0017] The network communications interface 218 receives a unique device identifier 214 from the edge device 206. In some implementations, the edge device 206 may communicate the unique device identifier 214 to the workload provisioning service 202 in response to a request from the workload provisioning service 202. In other implementations, the edge device 206 may communicate the unique device identifier 214 to the workload provisioning service 202 as part of a request by the edge device 206 for a workload from the workload provisioning service 202.

[0018] The unique device identifier 214 is communicated to the unique packaging key generator 220. The unique packaging key generator 220 generates a unique packaging key corresponding to the secure cloud workload and to the edge device 206 using the unique device identifier 214, a unique workload identifier corresponding to the secure cloud workload to be communicated to the edge device 206, and a nonce. The nonce may be generated by a nonce generator located on the workload provisioning service 202 on the datastore 232 or may be retrieved by the workload provisioning service 202 via a communications network.

[0019] The generated unique packaging key is used by the workload encryptor 222 to encrypt the secure cloud workload to be sent to the edge device 206. The secure cloud workload may be stored on a datastore located on the workload provisioning service 202 accessible by the workload encryptor 222, along with other secure cloud workloads for various edge devices. In some implementations, the secure cloud workload may be stored in another location communicatively connected to the workload provisioning service 202.

[0020] Along with encrypting the secure cloud workload, the workload encryptor 222 may, in some implementations, further package the secure cloud workload for communication to the edge device 206. For example, the workload encryptor 222 may, in some implementations, package the nonce for communication with the encrypted secure cloud workload as a single package. The workload encryptor 222 then communicates a packaged secure cloud workload 216 to the edge device 206 by communicating the packaged secure cloud workload 216 to the network communications interface 218. The network communications interface 218 communicates the packaged secure cloud workload 216 to the edge device 206 over a communications network.

[0021] The edge device 206 receives the packaged secure cloud workload 216 at a network communications interface 224. The network communications interface 224 communicates the packaged secure cloud workload 216 to a unique packaging key generator 226 on the edge device 206. The unique packaging key generator 226 cryptographically generates the unique packaging key using the unique device identifier, the unique workload identifier, and the nonce. The unique workload identifier may be communicated in a package with the packaged secure cloud workload 216. In some implementations, the nonce may also be communicated in the package with the packaged secure cloud workload 216. In other implementations, the nonce may be separately received by the edge device 206 from the workload provisioning service 202.

[0022] The unique packaging key generator 226 communicates the packaged secure cloud workload 216 and the generated unique packaging key to a workload decryptor 228. In some implementations, the workload decryptor 228 may be a trusted platform module (TPM) or part of a trusted execution environment (TEE) so that the unique packaging key is protected in a secure enclave. The workload decryptor 228 uses the generated unique packaging key to decrypt the secure cloud workload. The workload decryptor 228 then communicates the secure cloud workload to a workload execution environment 330. When the workload decryptor 228 is a TPM, the workload decryptor 228 communicates the secure cloud workload to the workload execution environment 230 outside of the secure enclave of the TPM.

[0023] When the workload decryptor 228 is part of a TEE, the workload execution environment 230 may be either fully or partially within the secure enclave. In some implementations, the workload execution environment 230 may be located partially within the secure enclave of the TEE. When the workload execution environment 230 is located partially within the secure enclave of the TEE, portions of the secure cloud workload requiring sensitive information or data may be executed within the secure enclave, while the remainder of the workload may be executed in a less secure portion of the workload execution environment 230.

[0024] FIG. 3 illustrates example operations 300 for generating an encrypted secure cloud workload for an edge device at a workload provisioning service. A receiving operation 302 receives a unique device identifier from an edge device. The unique device identifier is associated with the edge device. In some implementations, the edge device may send the unique device identifier to the workload provisioning service in response to a request from the workload provisioning service. In other implementations, the edge device may send the unique device identifier to the workload provisioning service as part of a request for a workload from the edge device to the workload provisioning service.

[0025] A generating operation 304 cryptographically generates a unique packaging key based on the received unique device identifier, a unique workload identifier corresponding to a secure cloud workload to be executed on the edge device, and a nonce. The nonce may be generated by a nonce generator that is part of the workload

provisioning service. Alternatively, the workload provisioning service may receive the nonce from a nonce generator through a communications network. The nonce is unique to the generation of the unique packaging key for the secure cloud workload on the edge device. The unique workload identifier corresponds to the secure cloud workload and may, in some implementations, be retrieved from a datastore located on the workload provisioning service. In other implementations, the unique workload identifier may be stored at another location and retrieved by the workload provisioning service via a communications network.

[0026] An encrypting operation 306 encrypts the secure cloud workload to generate a packaged secure cloud workload using the cryptographically generated unique packaging key. In some implementations, encrypting the secure cloud workload may include further packaging the secure cloud workload for communication to the edge device. For example, in some implementations, the nonce may be packaged for

communication with the packaged secure cloud workload as a single package.

[0027] A transmitting operation 308 transmits the packaged secure cloud workload to the edge device. The edge device is capable of independently cryptographically generating the unique packaging key using the unique device identifier, the unique workload identifier, and the nonce. The edge device is also capable of decrypting the packaged secure cloud workload using the generated unique packaging key cryptographically generated by the edge device. The packaged secure cloud workload is transmitted over a communications network and sent from a network communications interface of the workload provisioning service to a network communications interface of the edge device.

[0028] FIG. 4 illustrates example operations 400 for receiving and processing a secure cloud workload received from a workload provisioning service at an edge device. A providing operation 402 provides a unique device identifier to a workload provisioning service. The unique device identifier is associated with the edge device. The unique device identifier may be provided to the workload provisioning service in response to a request from the workload provisioning service. The unique device identifier may also be provided to the workload provisioning service as part of a request from the edge device to the workload provisioning service for a particular workload.

[0029] A receiving operation 404 receives a packaged secure cloud workload from the workload provisioning service. The packaged secure cloud workload is encrypted by the workload provisioning service using a unique packaging key generated by the workload provisioning service based on the unique device identifier, a unique workload identifier, and a nonce. In some implementations, the packaged secure cloud workload may include other information, including the nonce and unique workload identifier.

[0030] A generating operation 406 cryptographically generates, by the edge device, the unique packaging key using the unique device identifier, the unique workload identifier, and the nonce. The unique workload identifier may be communicated in a package with the packaged secure cloud workload. In some implementations, the nonce may also be communicated in the package with the packaged secure cloud workload. In other implementations, the nonce may be separately received by the edge device from the workload provisioning service.

[0031] A decrypting operation 408 decrypts the packaged secure cloud workload using the cryptographically generated unique packaging key cryptographically generated by the edge device. The decrypting operation 408 may occur at a workload decryptor of the edge device. In some implementations, the workload decryptor may be a trusted platform module (TPM) or part of a trusted execution environment (TEE) so that the unique packaging key is protected in a secure enclave. The workload decryptor uses the generated unique packaging key to decrypt the secure cloud workload.

[0032] When the workload decryptor is a TPM, the workload decryptor communicates the secure cloud workload to a workload execution environment outside of the secure enclave of the TPM. When the workload decryptor is part of a TEE, the workload may be executed either wholly or partially within the secure enclave of the TEE.

[0033] FIG. 5 illustrates an example computing device for use in generating an encrypted secure cloud workload. The example computing device 500 may be used to generate a packaged secure cloud workload for processing by an edge device. The computing device 500 may be a client device, such as a laptop, mobile device, desktop, tablet, or a server/cloud device. The computing device 500 includes one or more processor(s) 502, and a memory 504. The memory 504 generally includes both volatile memory (e.g., RAM) and non-volatile memory (e.g., flash memory). An operating system 510 resides in the memory 504 and is executed by the processor(s) 502.

[0034] One or more modules or segments, such as a workload provisioning service 540 are loaded into the operating system 510 on the memory 504 and/or storage 520 and executed by the processor(s) 502. The modules may include the workload provisioning service 540 implemented by a unique packaging key generator 542 and a workload encryptor 544. The unique packaging key generator 542 cryptographically generates a unique packaging key for encrypting a secure cloud workload. The workload encryptor 544 uses the generated unique packaging key to encrypt a secure cloud workload for communication to an edge device. The storage 520 may be local to the computing device 500 or may be remote and communicatively connected to the computing device 500 and may include another server. The storage 520 may store resources that are requestable by client devices (not shown).

[0035] The computing device 500 includes a power supply 516, which is powered by one or more batteries or other power sources and which provides power to other components of the computing device 500. The power supply 516 may also be connected to an external power source that overrides or recharges the built-in batteries or other power sources.

[0036] The computing device 500 may include one or more communication transceivers 530 which may be connected to one or more antenna(s) 532 to provide network connectivity (e.g., mobile phone network, Wi-Fi®, Bluetooth®) to one or more other servers and/or client devices (e.g., mobile devices, desktop computers, or laptop computers). The computing device 500 may further include a network adapter 536, which is a type of communication device. The computing device 500 may use the adapter and any other types of communication devices for establishing connections over a wide-area network (WAN) or local-area network (LAN). It should be appreciated that the network connections shown are exemplary and that other communications devices and means for establishing a communications link between the computing device 500 and other devices may be used.

[0037] The computing device 500 may include one or more input devices 534 such that a user may enter commands and information (e.g., a keyboard or mouse). These and other input devices may be coupled to the server by one or more interfaces 538 such as a serial port interface, parallel port, or universal serial bus (USB). The computing device 500 may further include a display 522 such as a touch screen display.

[0038] The computing device 500 may include a variety of tangible processor- readable storage media and intangible processor-readable communication signals.

Tangible processor-readable storage can be embodied by any available media that can be accessed by the computing device 500 and includes both volatile and nonvolatile storage media, removable and non-removable storage media. Tangible processor-readable storage media excludes intangible communications signals and includes volatile and nonvolatile, removable and non-removable storage media implemented in any method or technology for storage of information such as processor-readable instructions, data structures, program modules or other data. Tangible processor-readable storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CDROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other tangible medium which can be used to store the desired information and which can be accessed by the computing device 500. In contrast to tangible processor-readable storage media, intangible processor-readable communication signals may embody processor- readable instructions, data structures, program modules or other data resident in a modulated data signal, such as a carrier wave or other signal transport mechanism. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, intangible communication signals include signals traveling through wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared, and other wireless media.

The example computing device 600 may be used to process a packaged secure cloud workload received from a workload provisioning service. The computing device 600 may be a client device, such as a laptop, mobile device, desktop, tablet, or a server/cloud device. The computing device 600 includes one or more processor(s) 602, and a memory 604. The memory 604 generally includes both volatile memory (e.g., RAM) and non-volatile memory (e.g., flash memory). An operating system 610 resides in the memory 604 and is executed by the processor(s) 602.

[0040] One or more modules or segments, such as a secure workload processor 640 are loaded into the operating system 610 on the memory 604 and/or storage 620 and executed by the processor(s) 602. The modules may include the secure workload processor 640 implemented by a unique packaging key generator 642, a workload decryptor 644, and a workload execution environment 646. The storage 620 may be local to the computing device 600 or may be remote and communicatively connected to the computing device 600 and may include another server.
