| Abstract: | In this paper we suggest two new provable secure block ciphers, called BEAR and LION. They both have large block sizes, and are based on the Luby-Rackoff construction. Their underlying components are a hash function and a stream cipher, and that are provable secure in the sense that attacks which find their keys would yield attacks on one or both of the underlying components. They also have the potential to be much faster than existing block ciphers in many applications. |
