## Side-Channel Analysis

Side-channel analysis is a form of attack that extracts sensitive information from a hardware device by monitoring its physical characteristics, such as power consumption, electromagnetic emissions, or processing time. Rather than attacking the cryptographic algorithm directly, the attacker observes how the hardware behaves while performing computations.

For example, by measuring the power spikes during a signature operation, an attacker can sometimes deduce the bits of a private key. These attacks require specialized equipment and proximity to the target device, making them more common in physical security research than in remote attacks.

Manufacturers use techniques like power masking and constant-time execution to defend against these methods. Understanding side-channel vulnerabilities is essential for designing hardware that can withstand sophisticated physical tampering.

It highlights the reality that hardware security is as much about physical implementation as it is about software logic.
