Abstract: A decryption method includes receiving encrypted data, in which the encrypted data is encrypted by an RSA public key; and performing at least one multiplication operation and at least one square operation according to an RSA private key and the encrypted data to acquire decrypted data. A false square operation is performed in performing one of the at least one multiplication operation, or a false multiplication operation is performed in performing one of the at least one square operation.

Abstract: A decryption method includes receiving encrypted data, in which the encrypted data is encrypted according to an RSA public key; and performing a plurality of operations in sequence according to an RSA private key and the encrypted data to acquire a decrypted data. The operations include a plurality of decryption operations and at least one false operation. The decryption operations include at least one decryption multiplication operation and at least one decryption square calculation, and the at least one false operation includes at least one of at least one first false multiplication operation and at least one first false square calculation.
