This paper proposes a modified approach to data security using the concept of genetic algorithm and RSA cryptography to encrypt and decrypt the data. Genetic algorithms are a class of optimization algorithms which can be used to solve many problems through modeling a simplified version of genetic processes. Using Genetic Algorithm we can keep the strength of the key to be good, still make the whole algorithm good enough. We introduce a modified ciphering technique that lead to a modified ciphering system that can be used in encrypting data. This system is combination of symmetrical system using Genetic algorithm Inspired Cryptography and asymmetrical system using RSA cryptography to make the key very complex to reinforce resistance to cryptanalysis. The first operation is asymmetrical using genetic optimization to generate the key. The second operation of the modified ciphering technique is by using RSA algorithm. The key produced is non-repeating and thus making the cipher almost difficult to break. The feature of such an approach includes high data security and high feasibility for practical implementation.
