摘要
基于SM9-IBE密码算法,提出了一种适用于轻量级设备的高效在线/离线加密方案,以解决轻量级设备加密重要数据的时效性问题。通过将复杂计算进行预处理实现加密轻量化,对方案进行安全性证明和时间性能分析,与传统的SM9-IBE算法相比,改进的SM9-IBE算法在保证安全性的同时提高了加密速度和轻量级设备的资源利用率,具有较好的安全性和时间性能。
Based on the SM9-IBE cryptographic algorithm, an efficient online/offline encryption scheme for lightweight devices is proposed to solve the timeliness problem of encrypting important data by lightweight devices.By preprocessing the complex computation, the lightweight encryption is realized. Then, the security proof and time performance analysis of the scheme are carried out. Compared with the traditional SM9-IBE algorithm, the improved SM9-IBE algorithm improves the encryption speed and the resource utilization rate of lightweight devices while ensuring the security, and has better performance and practicability.
