In this paper, inspired by network coding theory we propose an efficient hybrid encryption-coding algorithm that requires using traditional encryption only for the first small amount of data. This amount of data, which we refer to as the first block, is determined by the traditional encryption algorithm to be applied on this first block. In our proposed algorithm, all the rest of the information will...
Recently, a new authentication scheme with anonymity for wireless communications has been proposed, and then some security problems have been demonstrated. In this paper, we will discuss a few problems found in the enhanced scheme and then propose how to overcome them, regarding the properties of anonymity and backward secrecy.
