<p>PURPOSE: An encrypting method using a seed algorithm is provided to perform cost-effectively a calculation process by including masking steps with random numbers. CONSTITUTION: An input plain text is masked with a first random number. The masked input plain text is defined as an initial input. The round key of a corresponding round for each round is masked with a second random number. The right input of input values of each round is encrypted with the masked round key. The encrypted right input and the encrypted left input are processed by an XOR operation. The processed result is masked with a third random number.</p> |
