摘要:
The present invention relates to a security access control method and system for wired local area network, the method includes the following steps: 1) a requester (REQ) negotiates the security policy with an authentication access controller (AAC); 2) the requester (REQ) and the authentication access controller (AAC) authenticate the identity; 3) the requester (REQ) negotiates the key with the authentication access controller (AAC). The direct identity authentication between the user and the network access control device is realized by the present invention; the negotiation and the dynamic update of the session key for the link layer data protection are realized; a variety of network architectures such as the enterprise network, the telecommunication network are supported; the scalability is good, the multiple authentication methods are supported; the authentication protocols with different security levels are supported, the requirements of the various subscribers are satisfied; the sub-modules of the protocol are independent, flexible, and easy to be accepted or rejected.
摘要:
A method and system for pre-shared-key-based network access control are disclosed. The method includes the following steps: 1) security policy negotiation is implemented between a REQuester (REQ) and Authentication Access Controller (AAC); 2) identity authentication and uni-cast key negotiation are implemented between REQ and AAC; 3) a group-cast key is notified between REQ and AAC. Applying the method and system, rapid bidirectional authentication can be implemented between a user and network.

摘要:
A method and a system for establishing a security connection between switch equipments are disclosed in the present invention. The system includes the first switch equipment and the second switch equipment; the first switch equipment sends the switch key negotiation activation packet and the switch key negotiation response packet to the second switch equipment; the second switch equipment sends the switch key negotiation request packet to the first switch equipment. The embodiments of the present invention provide a security policy for data security transmission between switch equipments by establishing shared switch key between each two switch equipments, thus guaranteeing the confidentiality of the data transmission process between switch equipments in the data link layer. The calculation burden of switch equipment and the delay of the data packets transmitted from the transmission end to the reception end can be reduced and the efficiency of network transmission can be improved.

摘要:
A switch route exploring method, system and device are provided in the present invention. The method comprises that: a transmitting source node NSource constructs a switch route exploring request packet and transmits it to a destination node NDestination; the switch route exploring request packet comprises information of switch route from the transmitting source node NSource to the destination node NDestination, wherein the information is known by the transmitting source node NSource; and the destination node NDestination constructs a switch route exploring response packet and transmits it to the transmitting source node NSource.
摘要:
The present invention provides a secret communication method, apparatus and system. The method comprises: 1) determining a neighboring encryption switching equipment shared by a first user terminal and a second user terminal, wherein the first user terminal and the second user terminal are neighboring user terminals (1); 2) establishing, by the neighboring encryption switching equipment, an inter-station key for communication between the first user terminal and the second terminal (2); 3) performing data secret communication between the first user terminal and the second terminal by using the inter-station key (3). With the present invention, the neighboring user terminals needing to perform the secret communication can establish the inter-station key without performing identity authentication with each other, and can perform the secret communication with the inter-station key, and thereby the network load is reduced.
