“…It shows that techniques which were originally developed for improving the throughput of digital filters with feedback can be also applied to hash function implementations. For more information about hardware design for cryptographic hash function we refer the reader to [43].…”

Embedded devices need both an efficient and a secure implementation of cryptographic primitives. In this chapter we show how common signal processing techniques are used in order to achieve both objectives. Regarding efficiency, we first give an example of accelerating hash function primitives using the retiming transformation, a well known technique to improve signal processing applications. Second, we outline the use of some special features of DSP processors and techniques earlier developed for efficient implementations of public-key algorithms. Regarding the secure implementations we outline the concept of side channel attacks and show how a multitude of techniques for preprocessing the data are used in such scenarios. Finally, we talk about fuzzy secrets and point out the use of DSP techniques for an important role in cryptography-a key derivation.

This paper presents two implementations of BLAKE hash family algorithm that has been selected as one of the SHA-3 competition finalist. The first implementation is a modification from the implementation of Beuchat et al. which significantly reduces the required ROM size up to 36% from the original requirement with small trade-off in additional logic circuit. The second implementation is an extension from Half-G structure that was designed to be flexible for different kinds of application. The highly compact BLAKE-256 design uses 356 LE and 9776 bits of memory when implemented in Cyclone III FPGA. Regular datapath design requires 369 slices and 1 memory block in Virtex 5 FPGA. Both designs are fully autonomous, which means that these designs do not require any additional memory or logic outside its system.Index Terms-SHA-3 competition, BLAKE, hardware implementation, FPGA 157

Hardware design for Hash functions

Abstract: The design philosophy of the most commonly used hash algorithms such as MD5, SHA family and RIPEMD is based on design principles of the MD4 family. In this section we will give a short overview and provide historical facts about existing attacks on these algorithms.
