摘要
A method for encryption authentication according to the present invention comprises the steps of: performing a first encryption operation by a first function using secret information; performing a second encryption operation by a second function using the result value of the first encryption operation without the secret information; and performing a third encryption operation by a third function using the result value of the first encryption operation or the result value of the second encryption operation and the secret information. Further, a method for decryption verification according to the present invention comprises the step of determining whether to output, to the decoding module, a value associated with the entire or partial value of the result value of the first encryption operation according to the result value of the third encryption operation.
