The ubiquity of wireless communication systems has resulted in extensive concern regarding their security issues. Combination of signaling and secrecy coding can provide greater improvement of confidentiality than tradition methods. In this work, we mainly focus on the secrecy coding design for physical layer security in wireless communications. When the main channel and wiretap channel are noisy, we propose a McEliece secure coding method based on LDPC which can guarantee both reliability between intended users and information security with respect to eavesdropper simultaneously. Simulation results show that Bob’s BER will be significantly decreased with the SNR increased, while Eve get a BER of 0.5 no matter how the SNR changes.

This paper deals with the design and implementation of the post-quantum public-key algorithm McEliece. Seamless incorporation of a new error generator and new SHA-3 module provides higher indeterminacy and more randomization of the original McEliece algorithm and achieves CCA2 security standard. Due to the lightweight and high-speed implementation of SHA-3 module the proposed 128-bit secure McEliece architecture provides 6% higher performance in only 0.78 times area of the best known existing design.
