However, the acquisition, dissemination, and maintenance of host identifiers are very different from IP addresses, and it is impossible to directly use source address verification technology to verify identifiers.

The invention discloses a real user identity-oriented host moving method. The method comprises the following steps that: when accessing a first network from an off-line state, a host interacts with an identifier server in the first network to verify whether the user identity of the host is legal or not, and if the user identity of the host is legal, the identifier server in the first network generates a host identifier by using user identity information and generates an Internet protocol version 6 (IPv6) address of the host in the first network based on the host identifier; and when moving from the first network to a second network, the host interacts with an identifier server in the second network to verify whether the user identity and the host identifier are legal or not, and if the user identity and the host identifier are legal, the identifier server in the second network generates the IPv6 address of the host in the second network based on the host identifier. According to the method, the problem of insufficient security of the IPv6 address in the prior art is solved by embedding the identifier which is generated by using the user identity information into the IPv6 address, and the identifier is prevented from being forged.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a host mobile method oriented to real user identities. Background technique [0002] At present, there is a kind of technology that supports host mobility in the Internet. By assigning relatively constant identifiers to terminal hosts to maintain the continuity of transport layer sessions, and maintaining the mapping from identifiers to IP addresses in the network, IP address-based data transmission. [0003] However, in this type of method, the user can achieve the purpose of forging his own identity by forging the source identifier, which makes this type of mobility method have certain security problems. [0004] The Identifier-Locator Network Protocol (ILNP) method uses the last 64 bits of the IPv6 address as the host identifier, but this method lacks a corresponding security mechanism to ensure the validity of the identifier. Users can generate arbitrary identifiers on...
