Image Encryption Using Hash Function and Entropy Function
Keywords:
Image Encryption, Image Decryption, Cryptography, Entropy, Information measureAbstract
In this paper, two way security is purposed; in which the first part of the algorithm presents the image encryption based on MD5 Hash function and in the second part we use the entropy function. The distinct characteristics of the algorithm are : high security, high sensitivity and high speed that can be applied for encryption of gray-level and color images. The hash function performs the partial encryption. The Entropy function generates a key that helps jumble the information. Both security and performance aspects of the proposed algorithm are analyzed and satisfactory results are obtained.
