RSA算法在DSP芯片上的加速实现

摘要

RSA is an important public key algorithm and is widely used in data encryption and digital signature. Using PC Security Card to implement data encryption is more secure and faster than using software. In this paper,we discuss the design of PC Security Card based on TMS320C54x chipset. By analyzing its instruction set,we project a method to improve the speed of RSA on this chip.%RSA是一种应用广泛的公钥算法，其原理简单，安全性好，但加密速度较慢。用硬件实现数据保护在安全性和速度上都能得到更好的性能。该文介绍了一种有效实现硬件数据加密的方案——基于TMS320C54x芯片的PC安全卡，并通过分析TMS320C54x芯片的特点，提出了一种在PC安全卡上加速实现RSA算法的方法，取得了良好的加速效果。
