摘要:
An entity authentication method by introducing an online third party includes the following steps: 1) an entity B sends a message 1 to an entity A; 2) the entity A sends a message 2 to a trusted third party TP after receiving the message 1; 3) the trusted third party TP checks the validity of the entity A after receiving the message 2; 4) the trusted third party TP returns a message 3 to the entity A after checking the validity of the entity A; 5) the entity A sends a message 4 to the entity B after receiving the message 3; 6) and the entity B performs validation after receiving the message 4. The online retrieval and authentication mechanism of the public key simplifies the operating condition of a protocol, and realizes validity identification of the network for the user through the authentication of the entity B to the entity A.

The invention involves a method and a system for station (STA) switching when a wireless terminal point (WTP) completes wireless local area network (WLAN) privacy infrastructure (WPI) in a convergent WLAN. The method includes steps as follows. The STA implements re-association rebinding process with a target access controller (AC) over a target WTP. A base key is requested by the target AC from an associated AC. An associated WTP is informed to delete the STA by the associated AC, and the target WTP is informed to add the STA by the target AC. A session key is negotiated based on the requested base key by the STA and the target AC, and is synchronized between the target AC and the target WTP. The method enables fast and safe switching of the STA between WTPs under the control of different controllers in the convergent WLAN based on WAPI protocol.

A method for realizing a convergent Wireless Local Area Networks (WLAN) Authentication and Privacy Infrastructure (WAPI) network architecture with a split Medium Access Control (MAC) mode involves the steps: a split MAC mode for realizing WLAN Privacy Infrastructure (WPI) by an access controller is constructed through splitting the MAC function and the WAPI function of the wireless access point apart to a wireless terminal point and the access controller; integration of a WAPI and a convergent WLAN network system architecture is realized under the split MAC mode that the access controller realizes WPI; the association connection process is performed among a station point, a wireless terminal point and an access controller; the process for announcing the start of performing the WLAN Authentication Infrastructure (WAI) protocol between the access controller and the wireless terminal point is performed; the process for performing the WAI protocol between the station point and the access controller is performed; the process for announcing the end of performing the WAI protocol between the access controller and the wireless terminal point is performed; the secret communication process is performed between the wireless terminal point and the station point by using WPI.

The embodiments of the invention disclose an access method suitable for wireless personal area network (WPAN). After the coordinator broadcasts the beacon frame, according to the beacon frame, the equipment identifies the authentication demand and the authentication mode required by the coordinator to the equipment. If the coordinator has no authentication demand to the equipment, the equipment and the coordinator carry out the association processes directly; otherwise, based on a selected authentication mode and the corresponding authentication mechanism negotiation information, the equipment sends the authentication access request to the coordinator; then based on the authentication mode selected by the equipment, the coordinator carries out the processes of authentication and session key negotiation with the equipment; finally, the coordinator sends the authentication access response to the equipment, when the authentication state in the authentication access response is success, the equipment carries out the association processes with the coordinator. The processes of authentication and the session key negotiation can be based on primitive control, and also can be based on port control. If the equipment is associated with the coordinator successfully, the coordinator distributes a network address to the equipment, and therefore the equipment can communicate with the coordinator normally. The invention solves the technical problems of lower security and lower efficiency in the existing WPAN access methods.

An entity bidirectional-identification method for supporting fast handoff involves three security elements, which includes two identification elements A and B and a trusted third party (TP). All identification entities of a same element share a public key certification or own a same public key. When any identification entity in identification element A and any identification entity in identification element B need to identify each other, if identification protocol has never been operated between the two identification elements that they belong to respectively, the whole identification protocol process will be operated; otherwise, interaction of identification protocol will be acted only between the two identification entities. Application of the present invention not only centralizes management of public key and simplifies protocol operation condition, but also utilizes the concept of security domain so as to reduce management complexity of public key, shorten identification time and satisfy fast handoff requirements on the premises of guaranteeing security characteristics such as one key for every pair of identification entities, one secret key for every identification and forward secrecy.

A secure transmission method for broadband wireless multimedia network broadcasting communication includes the following steps: a secure channel between big base station and small base station is established by utilizing security protocols; the big base station distributes a Broadcast Traffic Encryption Key to each small base station through the secure channel; the small base station transmits the Broadcast Traffic Encryption Key to the user passing the authentication and authorization. The above solution solves the problem of broadcast secure communication of the big base station working in the mixed covering mode of large and small cells, realizes the identification of not only the user but also the base station, and ensures that only the authorized user can receive broadcast service.

A key management method, is an enhanced RSNA four-way Handshake protocol. Its preceding two way Handshake processes comprise: 1), an authenticator sending a new message 1 which is added a Key Negotiation IDentifier (KNID) and a Message Integrity Code (MIC) based on the intrinsic definition content of the message 1 to an supplicant; (2), after the supplicant receives the new message 1, checking whether the MIC therein is correct; if no, the supplicant discarding the received new message 1; if yes, checking the new message 2, if the checking is successful, sending a message 2 to the authenticator, the process of checking the new message is the same as checking process for the message 1 defined in the IEEE 802.11i-2004 standard document. The method solves the DoS attack problem of the key management protocol in the existing RSNA security mechanism.

Exemplary embodiments of systems, methods and computer-accessible medium can be provided for obtaining and verifying a public key certificate status. In particular, it is possible to construct and send a certificate query request, construct and send a combined certificate query request, construct and send a combined certificate status response, deliver a certificate status response, perform a verification by the general access point, and/or perform a verification by the user equipment. The exemplary embodiments address some of the deficiencies of conventional methods which have a complicated implementation as well as likely inability of such conventional methods to be applied to the network architecture of user equipment, a general access point and a server. The exemplary embodiments of the systems, methods and computer-accessible medium can obtain a user certificate status to provide certificate statuses of the user or the user equipment and the general access point when the user equipment accesses the network via the general access point. Message exchanges can be reduced, bandwidth and calculation resources can be saved, and higher efficiency can be achieved. According to another exemplary embodiment, by way of adding random numbers into the certificate query request and the combined certificate query request, as well as the message m, freshness of the certificate status response can be facilitated and even ensured, and security protection can be enhanced.
