In feistel cipher, the operations of encryption and decryption are very similar, usually requiring multiple rounds of encryption and decryption operations. Principle of Feistel network A round function is used in the Feistel network. This function receives two input parameters, namely the packet data ...

The modified accelerated-cipher design uses data-dependent permutations, and can be used for fast hardware, firmware, software and WSN encryption systems. The approach presented showed that ciphers using this approach are less likely to suffer intrusion of differential cryptanalysis than currently used ...

Cryptography - Feistel Block Cipher - A framework or design model called the Feistel cipher which is used to create different symmetric block ciphers, including DES. Components of this design framework can either be self-invertible, non-invertible, or in
