Abstract

The invention discloses an electric power big data encryption method based on hyperchaos, and relates to the technical field of data encryption, and the method comprises the following steps: generating a hyperchaos sequence as a key stream, and carrying out bitwise operation on the key stream and a plaintext data stream to obtain a ciphertext data stream; plaintext data is processed by adopting a compressed sensing technology, data transmission and storage overhead is reduced, and parameters of the hyperchaotic encryption system are optimized by using a quantum genetic algorithm; privacy removal processing is carried out on a ciphertext data stream, a sequence formed by real numbers of the ciphertext data stream is converted into a pseudo-random sequence formed by integers through a mapping method, the pseudo-random sequence serves as an encryption key, and data safety and anti-cracking capacity are enhanced. According to the method, the compressed sensing technology and the quantum genetic algorithm are introduced to solve the problem that a traditional cryptosystem is prone to falling into a local extremum to cause ciphertext potential safety hazards, the hyperchaotic data encryption system is optimized, and the algorithm can remarkably improve the data protection capability of power data on the premise of guaranteeing the privacy safety of customers, and the security of the power data is improved. And the potential safety hazard of the ciphertext is effectively reduced.
