The wireless physical channel parameters are recently used to provide secret key. However, the key generation usually suffers from the quantization errors due to the noise, which decreases the key agreement ratio (KAR) between authorized users. Most existing approaches achieve high KAR by discarding some channel parameters which may lower the key generation efficiency and therefore lower the encryption...
Security is an important issue in wireless communication systems as the wireless channel is unguided. Cryptographic techniques in the wired communication may be used to secure the wireless communication, but the characteristics of radio channel are not exploited efficiently. This paper proposes a simple key generation method for securing wireless communication. It assumes that each terminal is equipped...
