Reed–Solomon Code based Green & Survivable Communications Using Selective Encryption

Reliability and security are two major criteria for survivable communications in error-prone wireless environments. To ensure reliable communications, Forward Error Correcting (FEC) codes such as Reed-Solomon (RS) codes are employed for error detection and correction by adding redundancies into the original data to form code words. Secure data communications based on FEC are achieved in many traditional approaches by encrypting the whole code words, which is not computationally or energy efficient. In this paper, we propose a new selective encryption approach based on FEC code words to effectively sustain both green and survivable communications in wireless networking systems.
