This paper describes BEAST, a new blockcipher for arbitrary size blocks. It is a Luby-Rackoff cipher and fast when the blocks are large. BEAST is assembled from cryptographic hash functions and stream ciphers. It is provably secure if these building blocks are secure. For smartcard applications, a variant BEAST-RK is proposed, where the bulk operations can be done by the smartcard's host without knowing the key. Only fast keydependent operations remain to be done by the smartcard. Keywords
