The previous key recovery attacks against Helix obtain the key with about 288 operations using chosen nonces (reusing nonce) and about 1000 adaptively chosen plaintext words (or 23...
Randomness extractors are important tools in cryptography. Their goal is to compress a high-entropy source into a more uniform output. Beyond their theoretical interest, they have ...
Rabbit is a software-oriented synchronous stream cipher with very strong security properties and support for 128-bit keys. Rabbit is part of the European Union's eSTREAM portf...
Stream cipher Hiji-Bij-Bij (HBB) was proposed by Sarkar at Indocrypt’03. This cipher uses cellular automata (CA). The algorithm has two modes: a basic mode (B) and a self-synchro...
