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...

Many block cipher modes use an initialization vector (IV) to prevent dictionary attacks. If you use a NULL IV, your encrypted data is vulnerable to such attacks. Block ciphers break your data into blocks of fixed size. Block cipher modes such as CBC (Cipher Block Chaining) protect against ...
Both a. and b. None of the aboveAnswer: c. Both a. and b.Explanation:Avalanche effect and Completeness are the two characteristic properties of Block ciphers which differ them from stream ciphers.7) Encryption algorithms are divided into two categories based on the ___.Output type Input ...
What are the most common block sizes used in block ciphers? What is the difference between block ciphers and stream ciphers? What is a block cipher? What is the Advanced Encryption Standard algorithm and how does it work? Why is it necessary to treat data in chunks of blocks? Chapters and...
However, AES is not the only cipher algorithm widely used in the real world. For this reason, this study was undertaken to test the hypothesis that these two findings are applicable to implementation of other symmetric block ciphers on two generation of GPU. In this study, we targeted five ...
