Abstract: The Internet Security Association and Key Management Protocol (ISAKMP) is an important protocol utilizing securityconcepts needed for establishing Security Associations and cryptographic keys between two or more hosts in a netwoTk. This paper putsforward our implement approach of ISAKMP in using IPSEC to construct secure Virtual Private Networks(VPN) at first, then describes howISAKMP/oakley protocols initially establish security associations and exchange keys during the first phrase between two systems that wish tocommunicate securely in detail.

摘要： 因特网安全关联与密钥管理协议ISAKMP是在两个或多个主机之间可靠的建立安全关联和加密密钥的一个重要协议。首先介绍了它在用IPSEC构建的虚拟专用网VPN中的作为密钢管理的实现框架，然后详细分析了两个希望安全通信的系统之间如何使用ISAKMP/Oakley协议在第一阶段建立安全关联和交换密钥的过程。
