HomePlug AV Security Mechanisms

This paper describes the security mechanisms provided in the HomePlug AV specification. It highlights the AV approach for solutions to problems in detection of other nodes with which to form a network, efficient transmission of the initialization vector (IV), reducing risks of key and IV reuse, and implementing "push-button" security for casual users. A novel key agreement protocol based on channel adapted powerline communications is described and analyzed. It also describes mechanisms to allow extensibility for higher layer key distribution protocols.
