Considering digital image features with high volumes and video data‚ especially in real-time applications‚ the use of classic encryption methods like DES‚ AES‚ ...‚ is not efficient in terms of being time cosuming. In this article‚ a new method is proposed to encrypt digital images‚ using chos systems and utilizing DNA patterns. A central idea in the method suggested is to produce a pseudo-random DNA strand using chaos functions‚ which an encrypted strand is created‚ using the random strand and the
