Abstract
Ensuring the confidentiality of communications is fundamental to securing any network. This requirement becomes particularly important for wireless systems, where eavesdropping is facilitated by the broadcast nature of the wireless medium. Rather than physically guard the communication medium to provide confidentiality, the traditional approach is to employ cryptographic algorithms to ensure that only legitimate users can correctly interpret the messages, while all other entities fail to glean any useful information.
Portions of the material have appeared previously in “Secrecy Capacity of Independent Parallel Channels,” Proceedings of the Forty-Fourth Annual Allerton Conference, 2006.
