| Abstract: | 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 Self-invertible matrix
generation method the key matrix used for the encryption is selfinvertible.
So, at the time of decryption we need not to find the
inverse of the key matrix. This paper presents image encryption
technique using the Hill cipher. Here we presented a proposed
method of generating self-invertible matrix for Hill Cipher
algorithm. Moreover this method eliminates the computational
complexity involved in finding inverse of the matrix while
decryption. However, a main drawback of this algorithm is that it
encrypts identical plaintext blocks to identical ciphertext blocks
and cannot encrypt images that contain large areas of a single
color. Thus, it does not hide all ... |
