Side Channel Cryptanalysis

Side-channel cryptanalysis is a method of attacking cryptographic systems by exploiting unintended information leaks during encryption or decryption. Instead of directly attacking the math behind encryption, attackers focus on analyzing physical characteristics like power usage, timing variations, or electromagnetic emissions. These "side channels" provide insights into secret keys or data, undermining the security of even strong algorithms. Preventing side-channel attacks requires securing implementations and using techniques like randomization and noise to protect against unintended information leaks.
