RSA在DSP下的快速加密实现

RSA是最早提出的公钥密码体制，其原理简单，安全性好，但由于其密钥较长才能保证一定的安全性，因而计算量大，如果用软件加密其速度太慢，用硬件实现可以大大提高RSA的速度。DSP芯片系列提供了一种专用的乘法器，其完成一次乘法的时间只要一个周期，这使实现RSA的速度加快。介绍了一种适合DSP TMS320C54X芯片，用汇编语言实现的一种快速的RSA，并实现了良好的加速算法。

Implementation of RSA encryption algorithm using DSP Tms320C54X chip

RSA is the earliest public key algorithm. Its theory is very simple and its security is very high, but it must use a long key to assure its security, so its computation is very large. Using hardware to implement data encryption is more faster than using softer. A particular multiplier can compute a multiplication at a cycle, which can make RSA faster. A kind of the design of fast RSA implementation based on DSP TMS320C54X chipset, using assembler language is introduced. As a result, it gets a high speed.
