TrustZone架构下基于优化RSA的食品追溯可信采集方法

AbstractAiming at the problem that food safety traceability data is very likely to be tampered before being uploaded to the server, this article builds a trusted execution environment based on the TrustZone framework and uses technologies such as timestamp authentication. It also introduces Rabin, Huffman coding, and random components to build a reliable method of food traceability collection based on optimized RSA in the TrustZone framework. Experimental results show that this method can efficiently and securely encrypt food traceability data, prevent tampering, improve encryption speed, and reduce file magnitude.
