A rapid cryptography algorithm based on chaos and public key

Abstract

This paper is based on the combined application of chaotic and public key cryptosystems to support rapid cryptography algorithms, leveraging their individual advantages. To demonstrate this we designed a rapid knapsack public key algorithm utilizing double sequences, which themselves use a sequence of random numbers generated from interference of Logistic and Chebychev chaotic mapping. We also designed a chaotic pseudo-random number generator while analyzing its characteristics and used it for the implementation of the algorithm. Through simulation and comparisons with related algorithms transversely and longitudinally, we have developed a cryptographic algorithm with higher efficiency and better security.
