MAME: A Compression Function with Reduced Hardware Requirements

This paper describes a new compression function, MAME designed for hardware-oriented hash functions which can be used in applications reduced hardware requirements. MAME takes a 256-bit message block and a 256-bit chaining variable as input and produces a 256-bit output. Seen in the light of attacks on MD5 and SHA-1, our design strategy enables us to evaluate the security of MAME against known attacks. Our design considers the security of side channel attacks against HMAC constructions employing MAME. The main use of logical operations in the design allows us to achieve a hardware implementation of MAME requiring 8.1 Kgates on 0.18 µm technology.
