An underwater node authentication method based on symmetric polynomial and ECC algorithm

Abstract

The invention discloses an underwater node authentication method based on a symmetrical polynomial and an ECC algorithm, comprising the following steps: initialization, authentication, key exchange for a pair, and group key exchange. Initialization means that the base station in the network assigns security parameters and algorithms to member nodes such as buoys, cluster heads, and ordinary nodes, including symmetric polynomial shares, public and private keys, encryption algorithms, and message authentication code functions. Authentication and key exchange refers to the two-way authentication between the cluster head and the ordinary nodes through three communications, and the successful exchange of symmetric session keys. This authentication method can effectively resist man-in-the-middle attacks. Group key exchange means that after the authentication of the cluster head and all member nodes in the cluster is successful, the cluster head needs to generate a unique symmetric group key shared with all member nodes to realize the encrypted transmission of the cluster head broadcast message, which is convenient for the cluster head to communicate with the member nodes. management. The invention solves the problem of relatively high communication overhead for underwater node authentication, and effectively reduces the probability of data conflicts.
