Abstract

An efficient hybrid encryption-coding algorithm is disclosed that requires using traditional encryption only for the first small amount of data. This amount of data, the first block, is determined by the traditional encryption algorithm to be applied on this first block. In this algorithm, all of the rest of the information will then be transmitted securely over the wireless channel, using network coding, without a need for using traditional encryption. Unlike the traditional and opportunistic encryption algorithms, the algorithm achieves higher data rates and less avalanche error effect, and, at the same time, it is as secure as traditional encryption algorithms. Assuming the additive white Gaussian noise (AWGN) channel model employing our disclosed algorithm, we analyze its performance in terms of throughput and security level.
