Abstract

The paper presents the digrafid cipher, a cipher which combines the bifid and the trifid ciphers. A modified algorithm for implementing the digrafid cipher using 64-symbol alphabet is proposed. MATLAB-based software tool implementing encryption and decryption of English texts using the digrafid ciphers and 27-symbol (the classical version) or 64-symbol alphabet is presented in the paper. The software tool is designed for the course "Telecommunication Security" for the students in the specialty "Telecommunication Systems" at the University of Ruse. It will enable students to comprehend the principles of encrypting and/or decrypting English texts using digrafid ciphers.

CompSysTech '17: Proceedings of the 18th International Conference on Computer Systems and Technologies

The paper presents one of the classical ciphers in cryptography, the bifid cipher, a type of cipher that was used historically but now has fallen into disuse. Most classical ciphers can be practically computed and solved by hand. They are also usually ...

AIKED'07: Proceedings of the 6th Conference on 6th WSEAS Int. Conf. on Artificial Intelligence, Knowledge Engineering and Data Bases - Volume 6

A plaintext is separated into two parts, a fixed length part and a variable length part. The second part of the plaintext is encrypted to a cipher text using a key. In this paper, an encryption algorithm which encrypts the first part of the plaintext and ...
Enhancement of 3D-Playfair algorithm using dual key

Playfair cipher is the one of the well known polyalphabetic cipher. In this paper, we present a new approach for secure transmission of a message by a modified version of the Playfair cipher combining with the ex-or operation and dual key. To develop this ...
