Manual Optimizations for Efficient Designs

Requirement of very high performance (runtime) coupled with limited energy budgets naturally lead to the inclusion of cryptographic accelerators in today’s heterogeneous System-on-Chips (SoCs). Efficient accelerator design, however, needs a deep understanding of the cipher structure as well as hardware optimization principles. In this chapter, we discuss two such custom optimizations, which have been applied to the symmetric-key cryptographic primitives and since, have been integrated into the CRYKET toolflow.
