Secure Channel Coding Schemes Based on Polar Codes

In this paper, the authors propose two new frameworks for joint encryption encoding schemes based on polar codes, namely efficient and secure joint secret/public key encryption channel coding schemes. The issue of using new coding structure, i.e. polar codes in McEliece-like and RN-like schemes is addressed. Cryptanalysis methods show that the proposed schemes have an acceptable level of security with a relatively smaller key size in comparison with the previous papers. The results indicate that both schemes provide an efficient error performance and benefit from a higher code rate which can approach the channel capacity for large enough polar codes.
