In order to improve safety and reliability of secure communication system, we propose a joint encryption error correction coding scheme.In this scheme, a conflict-free interleaver parallel decoding method of Turbo codes is used, which is known simply as" efficient Turbo codes", and it is combined with chaotic encryption together.This scheme makes the information encryption and efficient Turbo coding step be completed at the same time, and explain the encryption/decryption process through the efficient parallel decoding method, and verify the feasibility of the scheme through the application of Turbo code in image transmission as an example.The Matlab simulation results show that, the scheme performance is more excellent and effective in security and reliability than the existing joint encryption and error correction coding scheme.Our proposed scheme may provide an excellent encoding candidate scheme for secure communication system.
