This paper presents a new block cipher (KAMKAR 1.0). It uses a structure that resembles that of the famous cipher Rijndael [Joan Daeman et al., (1999), Brain Gladman, (2003)] chosen as advanced encryption standard (AES) in October 2000. The difference between the two ciphers is that in our proposal the encryption process is made more key-dependent in ...

This paper considers modern secret-key block ciphers. The theory behind the design and analysis of modern block ciphers is explained, and the most important known attacks are outlined. Finally the Advanced Encryption Standard is discussed.

Differential Fault Analysis (DFA) was one of the earliest techniques invented to attack block ciphers by provoking a computational error. In the basic DFA scenario the adversary obtains a pair of ciphertexts both of which encrypt the same plaintext.

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.
