A Rapid Cryptography Algorithm Based on Chaos and Public Key

摘要

This paper is based on the combined applicationof chaotic and public key cryptosystems to support rapidcryptography algorithms, leveraging their individualadvantages. To demonstrate this we designed a rapidknapsack public key algorithm [1] utilizing doublesequences, which themselves use a sequence of randomnumbers generated from interference of Logistic [2] andChebychev [3] chaotic mapping. We also designed a chaoticpseudo-random number generator while analyzing itscharacteristics and used it for the implementation of thealgorithm. Through simulation and comparisons withrelated algorithms transversely and longitudinally, we havedeveloped a cryptographic algorithm with higher efficiencyand better security.
