| 摘 要： | 为了改善RSA算法解密和签名的性能,Fiat提出了batch RSA算法,但效果并不显著.针对现有计算机多核的特点,对batch RSA算法进行并行优化,使其在解密和签名时的速度得到大幅度提升,实验表明并行优化后平均加速比可达到4.75.

| Abstract: | Fiat had put forward the batch RSA to speed up the decryption and signing,but it wasn't very effecient.Considering the multi-core feature of present computers,this paper focused on the parallel optimization of batch RSA in order to further speed up decryption and signing.Experiments finally showed that the speedup can reach a factor of 4.75. |

| Keywords: | batch RSA accelerate parallel multi-core |
