Abstract
The invention introduces an apparatus for detecting errors during data encryption. The apparatus includes an encoding circuitry and an error detection circuitry. The encoding circuitry is arranged operably to realize an encryption algorithm including multiple rounds, in which of each round encodes plaintext or an intermediate encryption result with a round key. The error detection circuitry is arranged operably to: calculate redundant data corresponding to the intermediate encryption result; and output an error signal to a processing unit when finding that the intermediate encryption result does not match the redundant data at a check point during an encryption process.
