Secondly, some encryption algorithms are introduced, with the analysis and comparison for these encryption algorithms, the author designs an appropriate project to accomplish the end - to - end encryption. thirdly, this paper accomplish the design of an encryption scheme which combining the strongpoint of the rsa algorithm and the idea algorithm. the main process is as following : first, input the digital signal to the encryption device, and then the digital signal exclusive or with the keying sequence which is generated by key stream generator ( ksg ) and the ksg is based on the idea encrypting and deciphering algorithm, the secret key synchronization is also studied
本課題主要研究的內容是數字集群通信系統加密機制的研究，首先介紹了數字集群通信系統的安全保密機制，講述了單向和雙向鑒權的過程、單呼和群呼的空中介面加密過程及其密鑰的選用和管理，特別介紹了端到端加密;然後介紹了幾種常用的加密演算法，通過分析其優劣，提出了端到端加密的解決方案;最後完成了基於rsa演算法和idea演算法的數字集群通信系統加密方案的設計，其具體過程為將經過數字信號送入加密器里，和以idea加密演算法為基礎設計的密碼流發生器（ ksg ）產生的密碼序列進行加解密運算，並且研究了此加密過程的密碼同步問題。 -
