Achieving strong security based on fountain code with coset pre-coding

This study proposes an approach for achieving strong communication security based on explosive fountain code with coset pre-coding, where both main and wire-tap channels are memoryless binary erasure channels. Coset pre-coding is used to prevent the eavesdroppers from intercepting the confidential information from the leaked bits. Further, an explosive fountain code is designed to ensure the reliability and low information leakage. By this way, the proposed approach can keep strong security and reliability when the erasure probability of the main channel is slightly lower than that of the wire-tap channel. Extensive simulations are conducted to verify the correctness and effectiveness of the approach.
