Abstract
The present invention discloses a method and system for secret communication between nodes in a wired Local Area Network (LAN). The method of secret communication between nodes in the wired LAN includes the following steps: 1) a sharing key is established; 2) the route probe is exchanged; 3) the data communication is classified; 4) the secret communication is processed among the nodes. According to the different communication situations among the nodes, the method of secret communication between nodes provided in the present invention can process the classification and select an appropriate secret communication strategy; compared with per-hop encryption, the calculation load of the exchange equipment is reduced, and the transmission delay of data packets is shortened; compared with the method that inter-station keys are established in pairs of nodes in order to protect the communication secret, the key number is reduced, and the key management is simplified.
