| dc.description.abstract | Cipher Trigraphic Polyfunction (CTriPoly) developed by previous researchers is a modification
of the Hill Cipher technique in modern cryptography. It was built on the system using three
symbols or letters and more than one transformation of the original message. The modular
arithmetic of a key matrix plays an important role in the encryption and decryption processes.
A crucial aspect of the decryption process is to get the inverse matrix for involutory matrices.
The objective of this paper is to obtain some solution of L
2
2×2 ≡ A2×2 (mod N) and
subsequently generate suitable involutory matrices which will be used as an encryption key in
CTriPoly. This definitely reduces the computational time of finding the decryption key. | en_US |
