摘要： A method and apparatus is provided for security of an IP security tunnel using public key infrastructure, including the steps of receiving a request message which relates to a security service requested by a mobile node, determining if there is security association (SA) for the security service and determining if there is a public key related to a peer address when the SA does not exist, sending a certificate request message to a certificate authority (CA) when the public key does not exist and receiving a certificate response message which has a certificate that includes a public key. The method further includes the steps of performing an internet key exchange and SA establishment procedure with a peer corresponding to the peer address by using the certificate, completing the internet key exchange and the SA establishment, and encrypting a packet received from the mobile node, transmitting the encrypted packet to the peer, decrypting a packet received from the peer, and transmitting the decrypted packet to the mobile node.
摘要翻译：提供了一种使用公钥基础设施的IP安全隧道的安全性的方法和装置，包括以下步骤：接收与移动节点请求的安全服务相关的请求消息，确定是否存在安全性的安全关联（SA）服务，并且当SA不存在时确定是否存在与对等体地址相关的公共密钥，当公共密钥不存在时向证书颁发机构（CA）发送证书请求消息，并且接收到具有证书的证书响应消息包括一个公钥。该方法还包括以下步骤：通过使用证书，完成互联网密钥交换和SA建立，与对端地址相对应的对等体执行因特网密钥交换和SA建立过程，以及加密从移动节点接收的分组，发送将加密的分组发送到对等体，解密从对等体接收的分组，以及将解密的分组发送到移动节点。
