Information Encryption Algorithm Based on Aes and Hyperchaotic System

In recent years, online shopping has developed rapidly, and traditional express slips mark consumers 'names, phone numbers, addresses and other private information in plain text, which greatly increases the risk of information leakage. In this paper, a new plaintext encryption algorithm is designed based on the AES algorithm and the hyperchaotic system. This algorithm uses three four-dimensional hyperchaotic systems as candidate key generators, then randomly selects one of them using a random function, and finally combines the chaotic sequence generated by the key generator with good randomness and AES algorithm to encrypt the order information. Not only the key space of the algorithm is enlarged, but also the robustness of the encryption algorithm is improved. The user's private information can also be protected at the source, which prevents the user's information from leaking and improves the distribution efficiency of the terminal logistics node.
