Multimedia applications often serve high-bandwidth channels. Thus, if encryption is required, cryptographic security often conflicts with efficiency. In the current paper, we consider the efficiency of unbalanced Luby-Rackoff ciphers. Such ciphers can operate very fast on large blocks of data and can easily cope with flexible block sizes. Anderson and Biham proposed two unbalanced Luby/Rackoff ciphers: LION and BEAR. An even faster algorithm is BEAST (Block Encryption Algorithm with Shortcut in the Third round). Like BEAR and LION, BEAST is assembled from a key-dependent hash function and a stream cipher. BEAST it is provably secure if these building blocks are secure. We evaluate the JAVA performance of BEAR, LION, and BEAST. For the sake of comparison, we also evaluate the performance of some well-known proven 64-bit block ciphers.
