Abstract

See full text

A voltage attack detection circuit includes at least one voltage regulation circuit, at least one voltage sensor and at least one glitch sensor. The at least one voltage sensor is configured to receive at least one first voltage output by the at least one voltage regulation circuit respectively, and output at least one first signal respectively. The at least one first signal is configured to indicate whether it is under voltage attack of a duration in a first range and an attack strength in a second range respectively. The at least one glitch sensor is configured to receive at least one first voltage respectively, and configured to output at least one second signal respectively. The at least one second signal is configured to indicate whether it is under voltage attack of a duration in a third range and an attack strength in a fourth range.
