Vernam Cipher with Complement Method and Optimization Key with Genetic Algorithm

Abstract

Integrity is important aspect on the process of exchange data, because the originality of the data sent must be kept confidentiality from the irresponsible attacker. One of the algorithm on cryptography is Vernam Cipher which main focus on XOR operation for encryption and decryption process. The key length and the complexity of algorithm for key determination are very influential to avoid attacks. This aim of study is to modify Vernam Cipher with addition 2’s complement operation on encryption, decryption and key optimizing. Modified Vernam cipher generate random key by genetic approach to improve level of security and complexity of the algorithm.
