基于迭代加密的OFDM系统物理层安全算法
Algorithm for OFDM physical layer security based on iterative encryp-tion
摘要
Abstract
In this paper, a physical layer security algorithm combined with OFDM modulation is proposed, in order to overcome the disadvantages of the existing physical layer security algorithms which can not resist plaintext cipher-text attack. The modulation process is controlled by a secret key, namely the iterative interpolation of the IFFT input symbols. Theoretical analysis and simulation results have showed that the algorithm not only has a large key space, but also can resist plaintext cipher-text attack. With almost no obviously impact on the original system performance except for a small PAPR increase, the proposed algorithm has great encryption effect and anti-attack ability, which shows a high security.关键词
