Embodiment Construction

[0013] This embodiment adopts the following technical solutions: it mainly includes the following methods: 1. Summarize the relevance of the chaotic system, and analyze the feasibility of applying it to block ciphers; after the analysis of the chaotic signal, it can be found that the chaotic signal has randomness on the surface, but These signals are all generated by a certain equation, and the equation is deterministic, so the chaotic signal is deterministic in nature, and the spectrum of the chaotic signal is continuous.

[0014] 2. Summarize the analysis methods of block ciphers, emphatically introduce the differential analysis method, and provide theoretical support for the following texts; first, brute force attacks, then differential attacks, linear cryptanalysis, interpolation attacks, and key-related attacks.

[0015] 3. Introduce a chaotic block cipher CS algorithm applied to WSN, analyze the theoretical basis for its analysis by differential analysis, and then use dif...
