In view of the commonly - used block cipher and public key cryptography , this article focuses on the improvement we have made for the algorithms about aes , dbs , ecc and rsa . based on the dsp chip tms320c6201 from ti company , we have accomplished the speed of 0 . 92 usec per aes encryption / decryption , 1 . 335 usec per dbs encryption / decryption , and 3 针对目前信息安全体系中常用的分组密码和公钥密码算法,本文着重改进了des 、 aes的快速算法实现,并在基于ti公司dsp芯片tms320c6201的系统中实现了0 . 92usec加(解)密一个aes分组, 1 . 335usec加(解)密一个des分组, 3 . 585usec加(解)密一个tdea分组;同时通过改造,使montgomery约化更易于进行并行处理,并通过改进椭圆曲线密码( ecc )底层运算和倍点算法,使得rsa和椭圆曲线密码的实现速度得到了极大的提高。
