Bidirectional entity authentication method based on the credible third party
First Claim
1. A utility bidirectional entity authentication method based on a trusted third party, comprising:
- sending, by an entity B, a message 1 comprising an authentication parameter of the entity B to an entity A;
sending, by the entity A, a message 2 to a trusted third party TP, the message 2 comprising the authentication parameter of the entity B and an authentication parameter of the entity A;
receiving, by the entity A, a message 3 sent from the trusted third party TP, a checking result is comprised in the message 3 which is obtained by checking whether the entities A and B are legal by the trusted third party TP on a basis of the message 2; and
verifying the message 3, by the entity A, so as to obtain a verification result of the entity B, sending a message 4 to the entity B, by the entity A, for causing the entity B to perform verification based on the message 4 and obtaining a verification result of the entity A.

Abstract
A bidirectional entity authentication method based on the credible third party includes the steps that: entity A receives message 1 sent from entity B including the authentication parameters of said entity B, and sends message 2 to the credible third party TP, said message 2 including the authentication parameters of entity B and the authentication parameters of entity A; entity A receives message 3 sent from said credible third party TP, said message 3 including the checking result after checking that whether said entity A and entity B are legal based on said message 2 by said credible third party TP; entity A gets the authentication result of entity B after authenticating said message 3, and sends message 4 to said entity B to make entity B authenticating based on said message 4 and getting the authentication result of entity A. The invention simplifies the operation condition of the protocol, reduces the computing capability requirement of the authentication entity, and satisfies the high security requirement of the network device lack of resource.
