Abstract:

Establishing an underwater wireless sensor network (UWSN) with high energy efficiency and high security is of great significance for monitoring resource-rich oceans and lakes. Due to the resource-constraint of UWSN and the high-energy consumption of underwater wireless communication, most of the current research on wireless communication starts with low energy consumption and ignores security issues. As the first line of defense for Communications security, identity authentication plays an important role in the secure interaction of UWSN. This paper proposes a new password-based identity authentication scheme for UWSN, which uses the advantages of password authentication to reduce the dependence on public key infrastructure. Utilizing the hash function simulation key distribution center (KDC) reduces the dependence on the KDC, which avoids additional communication costs and single point of failure, achieves a higher security. Finally, the proposed authentication key exchange protocol is implemented, and the performance of the authentication scheme is evaluated.
