Side-channel attack resistance refers to the ability of a cryptographic system to withstand attacks that exploit information leaked during its operation, rather than attacking the algorithm itself. This type of resistance is crucial for ensuring that sensitive data remains secure, as attackers may use various physical observations like timing information, power consumption, or electromagnetic leaks to gain insights into secret keys or other critical components. By enhancing side-channel attack resistance, cryptographic protocols can provide stronger security guarantees in environments where physical security cannot be assured.
