What is hardware security?

Abstract

Historically, the dominant technological and application trends have had a direct impact on the key integrated circuits design metrics. In the 70s, the silicon area was a scarce and expensive commodity. Therefore, development of techniques such as hardware sharing and design simplification was of prime importance. In the 80s, the premier design metrics was the speed of computation while in the 90s, the quest for power and energy optimization emerged. Initially, the emphasis was on minimizing the switching power but the focus has gradually moved towards minimizing the leakage energy.
