摘要
针对食品安全追溯数据在上传服务器前易遭到篡改的问题,在TrustZone架构基础上,利用时间戳认证等技术搭建可信执行环境,同时引入Rabin、霍夫曼编码和随机分量,构建TrustZone架构下基于优化RSA的食品追溯可信采集方法。实验结果表明,该方法可以高效、安全地对食品追溯数据进行加密,防止篡改,并且提高加密速度,降低文件量级。
Aiming at the problem that food safety traceability data is very likely to be tampered before being uploaded to the server, this paper adoptd technologies such as timestamp authentication to build a trusted execution environment based on the TrustZone framework. It introduced Rabin, Huffman coding, and random components to construct a reliable collection method for food traceability 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.
