From uncertainty to secrecy: A dynamic approach

Uncertainty is the pseudonym for many unfavorable effects in both wired and wireless communications. When uncertainty presents itself, a receiver suffers from information loss and communication efficiency is limited. Moreover, an adversary eavesdropping on the communication also faces inevitable information loss. This information loss can be utilized by legitimate users for security purposes. In this paper, we introduce the framework of utilizing adversary's information loss as a security measure. Moreover, we propose a set of light-weight algorithms to generate a series of hash values, namely dynamic secrets, from communication traffic and then apply dynamic secrets to secure the communications.
