An Attack Scheme of RSA Encryption System with Protocol Failure

RSA encryption algorithm is widely used in information and communication systems to protect the security of information. But the protocol failure would bring a lot of risks to RSA encryption systems. In this paper, the security of RSA encryption system and detailed risks brought by protocol failure which is result of improper choices of parameters discussed. Furthermore, an at-tack scheme of these risks and corresponding pseudo-code are proposed in this paper. This attack scheme would provide warnings for designers and users of RSA encryption systems.
