Image Encryption Using Modification Blowfish Algorithm

At present, the need for information security has become a necessity. Chaos is widely used in the cryptographic system as a cryptographic keys generator. These keys are the most important component in the system because the security of the cryptographic system depends entirely on its quality. These values of chaos will be used as keys for blowfish instead of original keys in rounds. This modification algorithm with messy obtained, better and faster results, Where the average time, correlation and entropy to encryption five images respectively is 0.09, 7.9271and 0.10988.
