Addressing method and method and apparatus for establishing host identity protocol (HIP) connections between legacy and HIP nodes
Abstract:
A method is provided of at least partially securing communications, via a HIP proxy (16), between a first host (12) which is not HIP enabled and a second host (14) which is HIP enabled, the method comprising: sending (A) a query from the first host (12) to resolve the IP address of the second host (14); in response to said query, retrieving (B, C) an IP address (IPfa) and HIT (HIThip) associated with the second host (14), returning (E) from the proxy (16) a substitute IP address (IPres) associated with the second host (14), and maintaining (D) at the proxy (16) a mapping between the substitute IP address (IPres), the retrieved IP address (IPfa) and the retrieved HIT (HIThip); and upon receipt (F) of a session initiation message (TCP SYN) at the proxy (16) from the first host (12) including as its destination address the substitute IP address (IPres), using the mapping to negotiate a secure HIP connection (22) between the proxy (16) and the second host (14).
Abstract(Chinese):

提供了一种方法，至少部分地通过HIP代理（16）在不启用HIP的第一主机（12）和启用HIP的第二主机（14）之间进行通信，所述方法包括：发送（A ）来自所述第一主机（12）的用于解析所述第二主机（14）的IP地址的查询; 响应于所述查询，检索（B，C）与第二主机（14）相关联的IP地址（IPfa）和HIT（HIThip），从代理（16）返回（E）与之相关联的替代IP地址（IPres） 并且在代理（16）处维护（D）代替IP地址（IPres），检索到的IP地址（IPfa）和检索到的HIT（HIThip）之间的映射; 并且在代理（16）从第一主机（12）收到（F）会话发起消息（TCP SYN）时，使用映射来协商安全的HIP连接，该第一主机包括作为其目标地址的替代IP地址（IPres） （22）在代理（16）和第二主机（14）之间。
