Abstract
BEAR and LION are block ciphers introduced by Biham and Anderson in 1996. Their special feature is that they use very efficiently a hash function and a stream cipher, so that the hardware implementation of BEAR and LION becomes straightforward, assuming that the two other primitives are already present. In this paper we discuss their security starting from the strength of their building blocks.
