Subthreshold SRAM designs for cryptography security computations

Abstract

Cryptography and Security hardware designing is in continues need for efficient power utilization which is previously achieved by giving a range of trade-off between speed and power consumption. This paper presents the idea of considering subthreshold SRAM memory modules to gain ultra-low-power capable systems. The paper proposes modifying available crypto security hardware architectures to reconfigurable domain-specific SRAM memory designs. Although reliability is still a problem, we focus on the idea to design flexible crypto hardware to gain the speed as well as the reduced power consumption. © 2011 Springer-Verlag.
