面向虚拟数据空间的轻量级安全传输方法

Lightweight secure transfer method for virtual data space

针对传统AES(高级加密标准)等加密算法在对大规模的数据加密过程中会造成严重性能开销,虚拟数据空间用户需要一种轻量级数据安全保障方法的问题,提出了ShuffleEnc(乱序加密)——面向高性能计算虚拟数据空间的轻量级数据安全方法.该方法针对虚拟数据空间数据的特点,基于转置加密技术,通过乱序方法提供轻量级数据安全保障,满足虚拟数据空间用户需求.实验结果表明:即使采用AES-NI(英特尔高级加密标准指令集)专用指令集对AES进行加速,与AES的四种主流加密模式方法相比,ShuffleEnc加解密时间约为AES的25%.

Aiming at the problem that traditional encryption algorithms such as AES(advanced encryption standard) will cause serious performance overhead when encrypting large-scale data, while virtual data space users usually need a lightweight data security method,a lightweight data security method ShuffleEnc(shuffling based encryption) was proposed for virtual data space of high performance computing.According to the characteristics of virtual data space data, this method was based on permutation encryption technology and provided lightweight data security guarantee through out-of-order method to meet the needs of virtual data space users. Experimental results show that even the AES-NI(advanced encryption standard new instructions) instruction set is enabled for AES acceleration, compared with the four mainstream modes of AES, the encryption and decryption time of ShuffleEnc is only 25% of that of AES.
