Research on privacy information security encryption methods for ship communication networks
To improve the security of privacy information in ship communication networks,a secure encryption meth-od based on chaotic mapping and RC5 algorithm is proposed.Firstly,based on Logistic chaotic mapping,the chaotic encryp-tion process of network privacy information is iteratively obtained by perturbing variables in the main and auxiliary chaotic processes,and the chaotic sequence of network privacy information is used as the encryption key for privacy information;Then,through the round function and shift operation of the RC5 algorithm,the previously generated key and data are XOR bit by bit to achieve encryption processing of privacy information data in the ship communication network;Finally,the en-crypted data is scrambled through chaotic mapping to resist plaintext attacks and improve encryption security.The experi-ment shows that this method encrypts private information more efficiently and has better encryption effects,which can ef-fectively improve the security of ship communication networks.
