Data Security of Network Communication Information Based on Multiple Chaotic Mappings

To lessen the strain on network nodes’ storage, a group encryption technique is used in this paper to propose a data security encryption algorithm for network communication messages based on multi-chaotic mapping. The ciphertext feedback method is employed, effectively safeguarding the system against selective plaintext attacks by linking the encryption key and the shift space of each round to the ciphertext in addition to the multi-chaos mapping. This encryption algorithm is further protected against exhaustive attacks by using plaintext disambiguation. Tests show that the suggested algorithm has quick encryption times, good security, and plaintext sensitivity.
