Abstract
A method for enabling at least a part of a Smart Card (e.g. SIM card) is described where a one time activation code is generated in a server at a telephone operator. The activation code is sent via registered mail to a Smart Card user, in a cellular phone. When the user enters the activation code into the phone, the entry is transmitted to the server for verification. Upon successful verification, the server transmits an enabling command to the phone, thus enabling the intended part of the SIM card. This may enable PKI functionalities until now hidden in the SIM card and thus unavailable for the user. The user may then choose his signing PIN for authentication, encryption and transaction signing. In case of enabling PKI functions, all necessary generation of private and public keys and establishment of certifications are carried through when the activation code is verified.
