Image Encryption Using Advanced Hill Cipher Algorithm
The Hill cipher algorithm is one of the symmetric key algorithms that have several advantages in data encryption. But, the inverse of the key matrix used for encrypting the plaintext does not always exist. Then if the key matrix is not invertible, then encrypted text cannot be decrypted. In the Involutory matrix generation method the key matrix used for the encryption is itself invertible. So, ...
متن کاملAdvanced Partial Image Encryption using Two-Stage Hill Cipher Technique
Information security is a fast growing research field which includes numerous problems in it. Partial image encryption is one of the important problems in the field of image information security. This paper describes the partial image encryption in two ways using hill cipher technique. First encryption technique uses two slightly different keys to construct two self-invertible matrices, which a...

متن کاملA Comparative Performance Analysis of an Image Encryption Technique using Extended Hill Cipher
The security of digital images is concentrating much attention nowadays, and many image encryption algorithms have been proposed by different authors and researchers. In [1], an improvement over an algorithm for image encryption was proposed. This paper explains the result and analysis of the proposed algorithm in [1]. The paper also discusses about the analysis based on some performance factor...
متن کاملCryptanalysis of an image encryption scheme based on the Hill cipher
This paper studies the security of an image encryption scheme based on the Hill cipher and reports its following problems: 1) there is a simple necessary and sufficient condition that makes a number of secret keys invalid; 2) it is insensitive to the change of the secret key; 3) it is insensitive to the change of the plain-image; 4) it can be broken with only one known/chosen-plaintext; 5) it h...
