摘要： 网络安全系统中，加密算法十分重要,但在一般情况下加密的算法是公开的,其秘密在于密钥的管理。为了适应电子商务、数字货币等应用系统安全的要求，研究了DH（Diffie&Hellmam）密钥加密体制、公钥加密体制、KPS（Key Pre-distribution System）密钥加密体制的实现方法，对于在网络环境下开发各种应用系统有一定参考价值。

Abstract: The encryption algorithm is very important in the network security system, but it is often open to public and the secrets rely on the management of the key. In order to adapt the demand of the e-business and digital currency, etc., this paper investigates the realization of SK encryption mechanism, PK encryption mechanism and KPS encryption mechanism, which will help to develop various application systems in the network environment.
