A combined encryption and error-correcting scheme based on turbo codes
Wu Wenbin, Yang Yang, Zhiping Shi · 2013
An encryption method based on Turbo codes is proposed in this paper. In the scheme, two measures are adopted to encrypt information: Firstly, binary pseudo random sequence generated by Logistic chaotic mapping is used to encrypt the first output of Turbo codes, at the same time to control the generated matrix of the second and third output; Secondly, the output of interleaver is controlled by the secret key, which is associated with the interleaver chosen. Simulation results of the image transmission show that the scheme has good performance in security and error-correcting capability.
