摘要

Underwater acoustic networks (UANs) adopt acoustic communication. The opening and sharing features of underwater acoustic channel make communication in UANs vulnerable to eavesdropping and interfering. The applications of UANs such as underwater military, underwater warning and energy development are very demanding for the security level. Quantum computing poses a threat to security of the traditional public key cryptosystem such as large integer factorization and discrete logarithm. To solve these problems, a public key encryption algorithm is proposed based on number theory research unit (NTRU) for underwater acoustic networks. The traditional NTRU encryption scheme was improved and a new public key cryptosystem was provided. The algorithm combined the encryption algorithm with the identity of the node. Experimental results show that the key generation speed is very fast, and the speed of encryption and decryption is faster than RSA, ECC, ElGamal and other public key cryptosystems. It verifies that the encryption algorithm can resist quantum computing attacks.
