International Journal of Computational Intelligence Systems 5, no. AES is a block cipher developed by two Belgian. Block sizes vary (64 bits for DES, 128 bits for AES. Advanced Encryption Standard (AES) is used by numerous Internet protocols to provide data confidentiality. Most modern symmetric encryption algorithms are block ciphers. For different applications and uses, there are several modes of operations for a block cipher. Columnar transposition is a block cipher. If the input is larger than b bits it can be divided further. Li Wei, Da-wu Gu, Xiao-ling Xia, Chen Zhao, Zhi-qiang Liu, Ya Liu, and Qing-ju Wang. Block cipher is an encryption algorithm that takes a fixed size of input say b bits and produces a ciphertext of b bits again. "An Algebraic Fault Attack on the LED Block Cipher.". Jovanovic Philipp, Martin Kreuzer, and Ilia Polian. "A Fault Attack on the LED Block Cipher." Constructive Side-Channel Analysis and Secure Design (2012): 120-134. The strength of cipher depends up on the key length. The choice of block size does not directly affect to the strength of encryption scheme. The size of block is fixed in the given scheme. In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called blocks, with an unvarying transformation that. An encryption method that processes the input stream as groups of bytes that are fixed in size, typically 64, 128 or 256 bits long.
