Song Fei, Zhe Cui · Applied Mathematics & Information Sciences · 2013
Abstract: This paper presents a low-overhead secure network coding scheme. The randomness of chaotic sequence is extremely sensitive to initial conditions characteristic of the program, the combination of the chaotic sequence with the original source message vector to construct a new cryptosystem to achieve the perfect secrecy of the encoding scheme. The program only in the original random network coding system based on the source changes, the intermediate nodes remain unchanged; added only an interference signal at the source to guarantee the security of the encoding scheme. The analysis results show that the scheme can guarantee perfect secrecy, and send signals with minimal overhead.
