Some security-related operations a semiconductor chip performs can take a different time to compete depending on the values of the input data and the secret key. Careful timing measurement and analysis may allow recovery of the system’s secret key. This idea was first published in the scientific literature in 1996. Then later these attacks were successfully performed on an actual smartcard implementation of the RSA signature.
