Abstract
Prior to the execution of a program contained in a second chip card inserted in a terminal such as a mobile radio telephone terminal, in addition to a first chip card containing data and connected to a telecommunication network to which the terminal is linked, one of the cards is authenticated by the other, or the two cards are authenticated mutually. This double authentication ensures the authenticity of the program for its overall execution in the terminal and the origin of the second card, distributed through conventional channels, for the network operator.
Claims11
A process for executing an application program contained within a card in a mobile telecommunication terminal, said terminal comprising a first card, and a second card containing the application program to be executed, said method comprising the steps of:
- transmitting, from said second card to said first card, information pertaining to the application program to be executed;
- authenticating said second card via said first card, based upon said transmitted information;
- and
- executing said application program contained within the second card if the authentication is successful
- wherein the first card contains a subscriber identification module and communication information.
A mobile communications terminal, comprising:
- a first card for executing an application program contained within another card, said first card containing a subscriber identification module and communication information;
- and
- a second card, said second card containing the application program to be executed, wherein said first card comprises:
- means for receiving, from said second card, information pertaining to the application program to be executed;
- means for authenticating said second card, based upon said transmitted information;
- and
- means for executing said application program contained within the second card if the authentication is successful.
A first card for executing an application program contained within a second card, the second card containing the application program to be executed, the first card comprising:
- means for receiving, from the second card, information pertaining to the application program to be executed;
- means for authenticating the second card, based upon the information pertaining to the application program to be executed;
- and
- means for authorizing an execution of said application program contained within the second card if the authentication is successful
- wherein the first card contains a subscriber identification module and communication information.
