基于AES和ECC的云审计数据加密方案

Scheme of Cloud Audit Data Encryption Based on AES and ECC

针对云审计数据的单向加密所带来的数据传输及存储安全问题,提出了混合双向加密方案(Hybrid Bidirectional Encryption Scheme,HBES)。HBES私钥由事件发起者产生并本地化存储,其中,私钥由随机数通过映射规则得到,随机数的产生则由响应时间和外部因素决定。模拟实验结果表明:与单一加密方式相比,HBES在加密时间开销以及安全方面更加高效,在实现云端审计数据的加解密方面是切实可行的。

Focusing on the data transmission and storage security problem of one-way encryption of cloud audit data,HBES(Hybrid Bidirectional Encryption Scheme)was proposed to tackle this problem.HBES private key is brought by event sponsor and local storage,then random number which depends on response time and external factors generates private key by mapping rules.Corresponding simulation experiment advocates that compared with the one-way encryption method,HBES is a more effective and feasible way in encryption time,security and achieving the encryption and decryption of the cloud audit data.
