Feistel Cipher model is a structure or a design used to develop many block ciphers such as DES. Feistel cipher may have invertible, non-invertible and self invertible components in its design. Same ...

gfc is a C implementation of a Generalized-Feistel Cipher [1, alg. 3] for generating random permutations. It uses Speck 64/128 as the random function, and can generate permutations with up to 2^64 ...

Abstract: The rapid expansion of Internet of Things (IoT) deployments has accelerated sensor infrastructure development. However, resource-constrained embedded devices require cryptographic algorithms ...
