We consider a simple and secure way to realize a synchronous stream cipher from iterated hash functions. It is similar to the OFB mode where the underlying block cipher algorithm is replaced with the keyed hash function, adopting the secret suffix method[20]. We analyzed the key, the keystream and the necessary properties to assume from the underlying hash… CONTINUE READING
