Title:
ELECTRONIC SECURITY SYSTEM IN UNMANNED AERIAL VEHICLE, FOR HIGH-SPEED ENCRYPTION/DECRYPTION PROCESSING
Document Type and Number:
WIPO Patent Application WO/2021/080050
Kind Code:
A1
Abstract:
An electronic security system in an unmanned aerial vehicle, for high-speed encryption/decryption processing, according to the present invention, can comprise: a main processor unit for performing input/output processing on plaintext data to be transmitted to a ground control station of the unmanned aerial vehicle and/or on ciphertext data received from the ground control station; a buffer unit for temporarily storing the plaintext data and/or the ciphertext data in a plurality of queues; an extended memory interface control unit for generating a write completion signal when the plaintext data and/or the ciphertext data is completely stored, and reading the plaintext data or the ciphertext data stored in some of the plurality of queues when a read command is received; an encryption/decryption control unit for generating an encryption command or a decryption command for the data stored in the some of the queues when the write completion signal is generated, and generating a read command for the read when an encryption completion signal or a decryption completion signal for the data is received; and an encryption/decryption unit which encrypts, when the encryption command is received, the plaintext data through an encryption/decryption engine unit by using a decrypted security key, temporarily stores the encryption-completed ciphertext data, and then generates the encryption completion signal, and which decrypts, when the decryption completion signal is received, the ciphertext data through the encryption/decryption engine unit by using the decrypted security key, temporarily stores the decryption-completed plaintext data, and then generates the decryption completion signal.
