Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an energy-efficient identity authentication method in a multi-level cluster wireless sensor network. Background technique [0002] In wireless sensor networks, most of the current identity authentication methods between nodes use asymmetric key algorithms to realize direct identity authentication between point-to-point. First, each node stores a private key, and then uses the public key discovery mechanism to obtain the public key of the target node, and then realizes the identity authentication of the node through the method of matching the public key and the private key. Although people are constantly optimizing the process, the characteristics of the asymmetric encryption algorithm determine that the method consumes a lot of node energy. [0003] For multi-level clustered wireless sensor networks, there is no special identity authentication method at present. Using ...

Although people are constantly optimizing the process, the characteristics of the asymmetric encryption algorithm determine that the method consumes a lot of node energy

[0003] For multi-level clustered wireless sensor networks, there is currently no dedicated identity authentication method. Using a general identity authentication method will bring huge energy consumption, especially the huge energy consumption of cluster head nodes, which will seriously affect the survival time of the network.
