A digital signature method and apparatus using a Rivest, Shamir and Adelman (RSA) public-key cryptography based on Chinese Remainder Theorem (CRT) is provided for protecting against fault cryptanalysis. When a fault occurs in a part of a signature computed according to RSA public-key cryptography based on CRT, the fault is spread throughout the signature so that an attacker using fault cryptanalysis cannot derive a formula which can attack a secret key.
