An Improved Cryptanalytic Attack on Knapsack Cipher Using Genetic Algorithm
With the exponential growth of networked system and application such as eCommerce, the demand for effective internet security is increasing. Cryptology is the science and study of systems for secret communication. It consists of two complementary fields of study: cryptography and cryptanalysis. The application of genetic algorithms in the cryptanalysis of knapsack ciphers is suggested by Spillman. In order to improve the efficiency of genetic algorithm attack on knapsack cipher, the previously published attack was enhanced and re-implemented with variation of initial entry parameters and results are compared with Spillman results. The experimental result shows that the efficiency of genetic algorithm attack on knapsack cipher can be improved with variation of initial entry parameters.
