Abstract
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.
