In earlier version, authentication and key management protocol is called Privacykey management (PKM); and data protection protocols include two solutions based on DES-CBC and AES-CCM.
This paper introduces the process about encryption and decryption of RSA encryption algorithm, and analyzes testing prime number and producing privacykey and security of RSA algorithm.
论述了RSA加密算法的过程，分析了算法中素数测试、密钥产生和现阶段的安全性。

Meanwhile, through the privacykey analysis, the histogram analysis, the information entropy, the average value of gray change and the relevant analysis, the security of this algorithm is very high.
