Abstract:
A method for acquiring and authenticate public key certificate status, which includes steps: constructing and sending a certificate retrieval request (1), constructing and sending a complex certificate query request (2), constructing and sending a complex certificate status response (3), and forwarding certificate status response (4), general access point authentication (5), and user equipment authentication (6). The present invention solves the problem that the prior art is too complicated and not suitable for network structure with the user equipment (7), the general access point (8) and the server (9). The present invention supplies the certificate status of the user or the user equipment (7) and the general access point (8) by using the method of acquiring the user certificate status when the user equipment accesses network through the general access point, and so reduces procedure of message exchange and saves bandwidth and calculation resource, then has higher efficiency. It assures the novelty of the certificate status response (4) by including random in the certificate retrieval request (1), the complex certificate retrieval request (2) and message m, so it has better safety.
