Description

technical field [0001] The invention relates to cryptographic technology, in particular to an energy internet communication security system and method based on a chaotic system array. Background technique [0002] With the widespread application of energy Internet technology, energy network data is increasingly widely disseminated and stored on the Internet. Therefore, in order to effectively protect user information from being used by illegal persons, the fundamental measure taken is information confidentiality transmission and storage. There are many types of data in the Energy Internet, and the data volume is large. Most of the traditional encryption algorithms are designed for one-dimensional data flow. When traditional encryption algorithms are used for encryption, the encryption efficiency is low, and the encrypted data is vulnerable to attacks. [0003] Chaos refers to a random-like behavior generated by a nonlinear deterministic system, which has the characteristics ...

AI Technical Summary

Problems solved by technology

Although the low-dimensional chaotic system has the advantage of short calculation time due to its simple form, its key space is small and the complexity of the chaotic sequence is not high, resulting in low security of the cryptographic system and difficulty in resisting exhaustive attacks.

The high-dimensional chaotic system, especially the hyperchaotic system, has more than two Lyapunov exponents, and its nonlinear behavior is more complex and difficult to predict; in addition, the hyperchaotic system has more than 4 state variables, and the key space is larger
