Dynamic Key Exchange Method for Image Encryption
نویسنده
چکیده
In recent years, a variety of image encryption scheme has been proposed. A new color image encryption method based on dynamic key exchange is proposed in this paper. For real time image encryption and lesser amount of time. The algorithm lacks of the characteristic of diffusion because each pixel is operated individually and a chosen/known-plaintext attack can break the scheme. The 192-bit-long external secret-key(bigger key space). In the result of several experimental statistical analyses and key sensitivity tests prove the security robustness of the proposed cryptosystem.
