摘要
军用电子信息系统网络化带来的数据交互需使用安全传输技术保证交互过程的安全性。传统的加密方式带来的传输时延影响了系统的实时性,本文研究基于OpenCL的AES算法并行化技术,为安全传输提供快速加密的技术支撑。通过对AES算法并行化的研究分析,设计T盒取代原有的S盒替换、行位移、列混合的数据块加密操作。通过多粒度加密方式对比、内存分配对比实验找出最优化的存储策略和并行粒度,使得优化后的AES算法在同等硬件环境下取得了最大3.74的加速比,能适用于安全传输且满足系统实时性的需求。
The development of military electronic information system brings more data communication which security needs to be maintained by security transmission.However,traditional encryption method may lead to transmission delay and thus impact the real-time performance of system.Based on OpenCL parallel computing technology,our research aims to introduce optimized AES algorithm for security transmission.After examining AES algorithm,we have designed a new block encryption process T box to take place the previous S box substitution,shift rows and mix columns.In the meanwhile,an optimized storage strategy and a parallel encryption granularity are given by comparing the results of several different sets of granularity encryption and memory allocation tests.The accelerate rate of optimized AES algorithm have reached to 3.74 under the same hardware environment which make it meet the requirements of security and real-time of data transmission.
