Secure Wireless Communication With Dynamic Secrets

Free registration required

Executive Summary

This paper introduces a set of low-complexity algorithms that when coupled with link layer retransmission mechanisms, strengthen wireless communication security. The basic idea is to generate a series of secrets from inevitable transmission errors and other random factors in wireless communications. Because these secrets are constantly extracted from the communication process in real time, the authors call them dynamic secrets. Dynamic secrets have interesting security properties. They offer a complementary mechanism to existing security protocols.
