The invention define a new protection mechanism against attacks to security enforcing operation performed by cryptographic token and smart card. It is based on an attack detector which signal to the main elaboration system a potential attack situation. The invention offer an easy solution to SIM cloning problems of telecom operators which use old and breakable cryptographic algorithms such as the COMP-128 and does not want to invest many in updating the network authentication systems with more resistant authentication cryptographic algorithms. This is requirement is typical of the telecom operator of the emerging market which use not the state of the art in technology. |
