ARC: A Synchronous Stream Cipher From Hash Functions
White Papers In this paper, a simple and secure way to realize a synchronous stream cipher from iterated hash functions is considered. It is similar to the OFB mode where the underlying block cipher algorithm is replaced with the keyed hash function, adopting...
