## Power Analysis

Power analysis is a type of side-channel attack that involves monitoring the power consumption of a hardware device while it performs cryptographic operations. By analyzing the fluctuations in power usage, an attacker can often infer the secret key being used by the device.

This is particularly relevant for hardware security modules and smart cards used in financial services, as they often have exposed power pins. To defend against this, manufacturers implement power-leveling techniques and noise injection to mask the correlation between the computation and power usage.

It is a sophisticated attack that requires specialized equipment and deep knowledge of the target hardware's architecture. As such, it is a primary concern for the design of secure financial hardware that must withstand physical analysis by determined adversaries.
