Cryptanalysis of TWIS Block Cipher
2012TWIS is a 128-bit lightweight block cipher that is proposed by Ojha et al. In this work, we analyze the security of the cipher against differential and impossible differential attacks. For the differential case, we mount a full-round attack on TWIS and recover 12 bits of the 32-bit final subkey with 221 complexity.

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 ...

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

TWIS – A Lightweight Block Cipher
2009A new 128-bit block cipher, TWIS is proposed. It uses key size of 128-bits. The design targets to software environment for resource constrained applications. It is inspired from existing block cipher, CLEFIA. Although the proposed design uses less resources as compared to CLEFIA, it compares favorably with CLEFIA in terms of security provided.
