Non-Cryptography Authentication for Wireless Communications Based on Two Uncorrelated Attributes
Recently in modern wireless systems, the physical-layer authentication has been proved to be a viable technique that can be combined with the higher-layer cryptographic to enhance the communication security. The existing physical-layer authentication schemes are single-variable based to verify transmitter's identity. In fact, these kinds of techniques are not quite reliable as the obtained information based on one characteristic is relatively more vulnerable to various interferences. Herein, a novel two-variable cross-layer authentication scheme is proposed.
