For the same data and key, the ciphered data is varied with time, so the security of the algorithm is increased. We have used the pipelining concept in our design. Our DES is implemented on Xilinx Spartan-3e (XC3s500e). Final 16-stage pipelined design is achieved with data rate of 7.98...

7 Block Ciphers Chapter outline Basic background on block ciphers and algorithm-independent concepts are presented in §7.2, including modes of operation, multiple encryption, and exhaustive search techniques. Classical ciphers and cryptanalysis thereof are addressed in §7.3, including historical details ...
New Lightweight Block Cipher Design and Implementation on FPGA With the mass-deployment of pervasive (ubiquitous) computing, there is a high demand for lightweight ciphers to safeguard data on the constraint pervasive devices. For all the block ciphers in existence, the Advanced Encryption Standard ...
In cryptography, acipherrefers to an algorithm for encrypting and decrypting data, unlike a code. A code maps information to different codewords but a cipher uses a set of fixed rules or algorithms and transformsplaintexttociphertext, which is a random string of random characters. Ciphers can ...
