Embodiment Construction

[0037]The process of the method proposed by the present invention is as follows: firstly, the network completes the network initialization in an offline state, determines the authorized node, and issues an identity certificate for the authorized node, and generates and distributes an identity certificate for issuing a new node and completes the identity authentication process at the same time The required parameters; after the initialization is completed, the new node initiates the identity certificate issuance process to the trust group, and the new node selects any t authorized nodes that agree to participate in the identity certificate issuance to form the identity certificate issuance group, and the authorization in the identity certificate issuance group Nodes generate group signatures in a hop-by-hop manner; finally, new nodes generate identity certificates based on the group signatures of the identity certificate issuing group, and then nodes in the network that have iden...

Abstract

The method comprises: new node initiates an identification letter issuing request to all authorization node; after receiving the responses for agreeing to participate in issuing identification letter from at least t authorization nodes, the new node selects t authorization nodes from them; the selected authorization nodes use a hop-by-hop signature approach to incorporate with the new node to generate the group signature and to generate identification letter.

Description

technical field [0001] The invention relates to network security technology, in particular to a distributed identity certificate issuing method. Background technique [0002] Mobile ad hoc network (Mobile Ad hoc Network, MANET) is a special mobile network without the support of wired infrastructure. It is composed of a group of mobile terminals with wireless transceivers. autonomous network. Therefore, it has characteristics that general communication networks do not have, such as self-organization of the network, dynamic network topology, limited wireless transmission bandwidth, limitations of mobile terminals, multi-hop routing, and vulnerability to attacks, etc. [0003] The identity authentication of mobile nodes in mobile ad hoc networks is an important part of ensuring the normal operation of the network, and identity authentication can effectively prevent counterfeiting attacks. Traditional networks usually require a trusted authentication center to provide identity...
