RSA algorithm is one of the most widely used non-symmetric cipher system. On the base of the study of RSA algorithm theory,principle, algorithm description and so on,the paper further studies the details of the problems in the implementation of RSA algorithm that should be paid attention and its application in the encryption/ decryption, digital signatures, key exchange. Finally, the paper proposes a kind of private key power module operation improvement scheme. The scheme improved the speed of RSA algorithm in the decryption.%RSA算法是使用最广泛的一种非对称密码体制.在对RSA算法的理论基础、原理、算法描述等进行研究的基础上,近一步研究了RSA算法在实现时应注意的问题以及它在数字签名、密钥交换等方面的应用.最后提出了一种对私有密钥进行幂模运算的改进方案,提高了RSA算法在解密时的运算速度.
