A system and recording medium for securing data and methods thereof including a modular exponentiation. One embodiment includes first masking a message, second masking an exponent, and executing a modular exponentiation based at least one of the first and second maskings. Another embodiment includes first masking a message, second masking at least one exponent, executing a modular exponentiation based at least one of the first and second maskings, detecting an error, executing a modular multiplication operation based on the detection and diffusing the detected error to generate an electronic signature. Yet another embodiment includes first masking a message, second masking at least one exponent, executing a modular exponentiation based at least one of the first and second maskings, detecting an error, and generating an electronic signature based on the detected error. |
