As shown in Figure 1, system of the present invention has adopted the layering authentication mechanism, at first realizes the authentication of carrier network to the M2M terminating gateway, and authentication comprises to the authentication of equipment with to user's authentication, has guaranteed that the M2M terminating gateway do not distorted by malicious user, attacks or the clone; Then, realize of the authentication of M2M terminating gateway to the M2M terminal, authentication equally also comprises to the authentication of equipment with to user's authentication, by M2M terminal authentication of the present invention system, significantly reduced carrier network owing to support the professional and signaling traffic load of big leap ahead of M2M, thereby guaranteed the service quality of M2M service, and then guaranteed communication quality.
Below in conjunction with embodiment system of the present invention is realized that the method for authentication is described in detail.
Fig. 2 is the schematic flow sheet of the embodiment of the mutual authentication between M2M terminating gateway of the present invention and carrier network, as shown in Figure 2, may further comprise the steps:
Step 200: in the M2M terminating gateway, set in advance the key K v of equipment vendor's distribution and the key K o that operator distributes.Here, key K v and key K o need be stored in the dependable environment of M2M terminating gateway.
Step 201: the certificate server of carrier network is to the key K v of the request M2M of equipment vendor terminating gateway.In this step, the certificate server of carrier network need provide the unique sign that can discern the M2M terminating gateway to equipment manufacturers, such as Equipment Serial Number of M2M terminating gateway etc.
Step 202: equipment manufacturers return the key K v of the M2M terminating gateway of request to the certificate server of carrier network.In this step, communication between the certificate server of equipment manufacturers and carrier network needs authentication mutually, and the transmission of Information between them is promptly safe through what encrypt, specific implementation can adopt existing a lot of methods, belong to those skilled in the art's conventional techniques means, repeat no more here.
Step 203:M2M terminating gateway sends the request of inserting to carrier network, carries the user ID of M2M terminating gateway in inserting request, such as international mobile subscriber identity (IMSI, InternationalMobile Subscriber Identity) etc.
Step 204: carrier network is transmitted the request of access to certificate server.
Step 205: certificate server finds the key K v and the key K o of this M2M terminating gateway according to the user ID of M2M terminating gateway, and generates Ciphering Key according to them.The specific implementation of this step can adopt existing mode to realize, as the authentication mode-AKA of existing 3GPP network, and emerging mode etc., here and be not intended to limit the scope of the invention.
Step 206: certificate server is transmitted to carrier network with AKA Ciphering Key (RAND ‖ XRES ‖ CK ‖ IK ‖ AUTN).
Step 207: carrier network and M2M terminating gateway carry out key agreement mechanism (AKA, Authentication and KeyAgreement) authentication according to key and the equipment identities (key that operator distributes) that equipment vendor distributes.
By flow process shown in Figure 2, M2M terminating gateway and carrier network have been set up trusting relationship, and M2M terminating gateway and carrier network can be set up encrypted tunnel by this trusting relationship and protect signaling and media data.
Fig. 3 is the schematic flow sheet of the embodiment of the mutual authentication between M2M terminal of the present invention and the M2M terminating gateway, as shown in Figure 3, may further comprise the steps:
Step 300: set in advance the key K v ' of equipment vendor's distribution and the key K o ' that operator distributes in the M2M terminal, here, key K v ' and key K o ' are stored in the dependable environment of M2M terminal.
Step 301: the certificate server of carrier network is to the key K v ' of the request M2M of equipment manufacturers terminal.In this step, the certificate server of carrier network need provide the unique sign that can discern the M2M terminal to equipment manufacturers, such as Equipment Serial Number of M2M terminal etc.
Step 302: equipment manufacturers provide the key K v ' of the M2M terminal of request to the certificate server of carrier network.In this step, the communication between the certificate server of equipment manufacturers and carrier network needs mutual authentication, and the transmission of Information between them is promptly safe through what encrypt.
Step 303: the key K o ' that the certificate server of carrier network distributes the key K v ' of M2M terminal and operator, perhaps f (Kv ', Ko ') sends to carrier network.
In this step, and f (Kv ', Ko ') be a kind of function, this function with key K v ' and key K o ' as parameter, derive a sub-key, finish mutual authentication with this sub-key as shared key, effect is equal to key K v ' and key K o ' as shared key.Here need the M2M terminal also to do the same operation, derive an identical sub-key.
Step 304: carrier network is the key K v ' and the key K o ' of operator of M2M terminal, and perhaps f (Kv ', Ko ') sends to the M2M terminating gateway.
Step 305:M2M terminating gateway and M2M terminal are used and are shared key i.e. (key that equipment vendor distributes) Kv ' and (key that equipment vendor distributes) Ko ', perhaps f (Kv ', Ko '), the two-way authentication between realization M2M terminal and M2M terminating gateway.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
