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 [1] utilizing double sequences, which themselves use a sequence of random numbers generated from interference of Logistic [2] and Chebychev [3] 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.
