Abstract
An embodiment of the invention provides a fault-attack analysis device. The first encoder performs a first encoding operation on the first output result corresponding to the normal round calculation to generate a first encoding result. The first decoder performs a first decoding operation on the first encoding result to generate a first decoding result. The second encoder performs a second encoding operation on the second output result corresponding to the redundant round calculation to generate a second encoding result. The second decoder performs a second decoding operation on the second encoding result to generate a second decoding result. The second encoding operation and the second decoding operation are based on binary field addition. The comparison circuit compares the first decoding result to the second decoding result to perform a fault-attack analysis.
