Abstract
A storage element that is operable based on a system clock signal, the storage element including a clock gating circuitry configured to generate a gated clock signal based on at least one Boolean signal and the system clock signal or a preprocessed system clock signal, wherein the clock gating circuitry comprises physical connections of small capacitance such that tapping of at least one of the physical connections results in a hold-time violation. Also, a hardware-based cryptography accelerator or a secured processing system including at least one such storage element, and a method for operating at least one storage element.
Claims14
A storage element configured to operate based on a system clock signal, comprising:
- a clock gating circuitry configured to generate a gated clock signal based on:
- at least one Boolean signal, and
- the system clock signal or a preprocessed system clock signal,
- wherein the gated clock signal comprises a true gated clock signal and an inverse gated clock signal, and the clock gating circuitry comprises physical connections of small capacitance such that tapping of at least one of the physical connections results in a hold-time violation.
