Abstract |
Security of wireless transmission is a great challenge in secure communications. Classical methods are based on cryptographic algorithms. These methods require a secret key that must be generated securely between associated parties in communication. Another approach to security is based on wiretap channel concept and is applicable for wireless communications. Because of rather small secrecy capacity of this method, it is useful for initial secret key establishment process between communication sides. In this paper we introduce a communication model for secret key extraction from fading of channel and calculate the secrecy capacity for Nakagami and Suzuki fadings which are two complicated models having suitable matching with practical measurements. |
