Detailed explanation-1: -A side-channel attack (SCA) is a security exploit that attempts to extract secrets from a chip or a system. This can be achieved by measuring or analyzing various physical parameters. Examples include supply current, execution time, and electromagnetic emission.

Detailed explanation-2: -A cache side-channel attack works by monitoring security critical operations such as AES T-table entry or modular exponentiation or multiplication or memory accesses. The attacker then is able to recover the secret key depending on the accesses made (or not made) by the victim, deducing the encryption key.
