Document Type and Number:
WIPO Patent Application WO/2023/103697
Kind Code:
A1
Abstract:
A communication method in a computer system and a related product, capable of reducing loss caused by processes, running in different enclaves of the system, during communication. Specifically, the method above comprises the following steps: receiving a communication request from a first process (S101); and then creating a shared memory space according to the communication request (S102), wherein the first process and a second process have permissions to access the shared memory space, the first process is a process running in a first enclave, and the second process is a process running in a second enclave. The first process and the second process can access the shared memory space, so that the first process and the second process can perform read and write operations on the shared memory space, and thus can implement communication on the basis of the shared memory space. When communication is implemented on the basis of the shared memory space, data copying and data encryption are not needed in the procedure, and thus, the procedure will cause less loss.
