A side-channel attacker exploits information leaked from the physical implementation of a cryptosystem rather than theoretical weaknesses in the algorithm itself. This leaked information can include timing, power consumption, electromagnetic radiation, or sound. By measuring and analyzing these physical emanations during the cryptographic operation, an attacker can infer secret keys or other sensitive data.
For example, a timing attack might observe that certain operations take longer to complete depending on the
The effectiveness of side-channel attacks depends on the attacker's ability to precisely measure the physical emanations
