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