Enhanced Block Playfair Cipher
2013In this paper we will enhance the traditional Blick Playfair Cipher by encrypting the plaintext in blocks. For each block the keyword would be the same but the matrix will shift by some random value. As a result of which the diagram analysis would be very difficult which is done in the traditional Playfair Cipher to obtain the plaintext from the cipher

For much of human history, cryptography has generally been a stream-based concept: for example, a general writes down a note, and a soldier encrypts it letter-by-letter to be sent on. As written language is based on letters and symbols, it is natural that our initial designs for encryption and decryption algorithms operate on individual symbols ...

In this paper we present a new 96-bit block cipher called BKSQ. The cipher can be implemented efficiently on a wide range of processors (including smartcards) and in hardware.

In this paper, we propose a 128-bit block cipher ARIA which is an involution substitution and permutation encryption network(SPN). We use the same S-boxes as Rijndael to eliminate defects which are caused by a totally involution structure. In the diffusion layer of ARIA, a 16× 16 binary matrix of the maximum branch number 8 is used to avoid some ...

Several DES replacement block ciphers have been published. In this paper a report will be given on the development of a package for analysis and comparison of block ciphers. Experimental results are presented on applying this package to DES, FEAL-N, and Madryga ciphers.
