Abstract:Sosemanuk is word oriented synchronous stream cipher capable to produce 32 bit ciphertext. It uses variable key from 128 bit to 256 bit and publically known Initialization Vector (IV) of 128 bit. Sosemanuk is one of the finalists in Profile 1 of the eSTREAM Portfolio. This cipher targets to avoid structural properties of SNOW2.0 to improve its efficiency by reducing the internal state size. It also uses reduced round Serpent24 block cipher to provide secure and efficient key loading process. This paper present… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
