摘要
Methods and devices disclosed herein use techniques to resist glitch attacks when computing discrete-log based signatures. The methods and systems described herein replace the random nonce in conventional signature systems with a pseudorandom nonce derived in a deterministic way from some internal state information, such as a secret key or a counter, such that the nonce is not repeated. The methods and systems described herein may also use tests to verify that a glitch has not occurred or been introduced.
