An Improved Entity Authentication Mechanism for HF Digital Communication

Identity authentication is normally used in the control of safe accession to network in wireless systems, which is the base of security of the entire system. Identity authentication base on challenge/respond is widely utilized in traditional wireless systems, private-key cryptosystem is used in it, which has a complex procession of updating key and easy being attacked. Aim at this problem, corporate with traits of HF communication, this article brings forward to utilize on time password identity authentication base on RSA digital signature. Test result shows that the performances of this authentication protocol covered the security requirement of HF digital communication; it also greatly improves the security of HF network.
