| In this paper, methods of generating self-invertible matrix for Hill Cipher algorithm
have been proposed. The inverse of the matrix used for encrypting the plaintext
does not always exist. So, if the matrix is not invertible, the encrypted text cannot
be decrypted. In the self-invertible matrix generation method, the matrix used for
the encryption is itself self-invertible. So, at the time of decryption, we need not to
find inverse of the matrix. Moreover, this method eliminates the computational
complexity involved in finding inverse of the matrix while decryption. |
