Key generation for plain text in stream cipher via bi-objective evolutionary computing.
Applied Soft Computing(2018)
摘要
•We developed key generation algorithms in the bi-objective and the single objective optimization framework.•For encoding we employed the Mutated Huffman Tree Coding algorithm.•We encrypted the encoded key stream as well as the encoded plain text in order to generate the cipher text.•We then decrypted the cipher text using the encoded key stream and the decoded the deciphered text using the code tables.•The highest entropy value yielded by the NSGA-II-KGA, which in turn indicates the strength of the key generated.
