Cryptography

Leak the secret through physical measurement, not math

In cryptography, a side-channel attack recovers a secret not by breaking the underlying mathematics but by measuring a physical by-product of the computation, such as how long it takes, how much power it draws, or what electromagnetic signals it emits. Kocher's 1996 Timing attacks on implementations of Diffie-Hellman, RSA, DSS, and other systems showed that tiny, key-dependent variations in execution time could be exploited to extract private keys, opening the study of implementation-level leakage. The referent is an attack on how an algorithm is realised in hardware or software rather than on the algorithm itself, defended by constant-time code, masking, and noise.[1]

Unit
The secret information recoverable from a physical measurement of the computation
Recovery means
Not applicable
Measured by
Demonstrated by key recovery from timing, power, or electromagnetic traces, and quantified by the number of measurements needed
