ABSTRACT: In the ancient block Hill
cipher, the cipher text is obtained by multiplying the blocks of the plain text
with the key matrix. To strengthen the keymatrix, a double guard Hill cipher
was proposed with two key matrices, a private key matrix and its modified key
matrix along with permutation. In the ancient block Hill cipher, the cipher
text is obtained by multiplying the blocks of the plain text with the key
matrix. To strengthen the key matrix, a double guard Hill cipher was proposed
with two key matrices, a private key matrix and its modified key matrix along
with permutation. In this paper a novel modification is performed to the double
guard Hill cipher in order to reduce the number of calculation to obtain the
cipher text by using non-square matrices. This modified double guard Hill
cipher uses a non-square matrix of order (p × q) as its private keymatrix.
