An AES Based 256-bit Hash Function for Lightweight Applications: Lesamnta-LW
Summary :
This paper proposes a new lightweight 256-bit hash function Lesamnta-LW. The security of Lesamnta-LW is reduced to that of the underlying AES-based block cipher and it is theoretically analyzed for an important application, namely the key-prefix mode. While most of recently proposed lightweight primitives are hardware-oriented with very small footprints, our main target with Lesamnta-LW is to achieve compact and fast hashing for lightweight application on a wider variety of environments ranging from inexpensive devices to high-end severs at the 2120 security level. As for performance, our primary target CPUs are 8-bit and it is shown that, for short message hashing, Lesamnta-LW offers better tradeoffs between speed and cost on an 8-bit CPU than SHA-256.
