Abstract
A certification method using a public key certification authority (30) and involving at least one mobile terminal (10) able to receive messages encrypted by that public key. The mobile terminal (10) generates the public key, and a telecommunications network entity (20) acquires said key from the mobile terminal (10) by means of a network call. The network entity authenticates the mobile terminal (10) by a party authentication process used in relation to a standard telephone call. The certification authority (30) is supplied with the public key and the associated result of the authentication process.

A certification method using a public key certification authority (30) and involving at least one mobile terminal (10) able to receive messages encrypted by that public key, wherein the method comprises:
- the step of the mobile terminal (10) generating the public key;
- the step of a telecommunications network entity (20) acquiring said key from the terminal (10) by means of a network call;
- the step of the network entity authenticating the terminal (10) by a party authentication process used in relation to a standard telephone call;
- and
- the step of supplying the certification authority (30) with the public key and the associated result of the authentication process.
A mobile telecommunications system comprising
- at least one mobile terminal (10);
- and
- one network entity (20);
- means in the mobile terminal (10) for generating a public key);
- means in the telecommunications network entity (20) for acquiring said public key from the mobile terminal (10) by means of a network call;
- means for authenticating the mobile terminal by means of an authentication process used in relation to a standard telephone call;
- a certification authority;
- and
- means for supplying the certification authority with the public key generated by the mobile terminal and the associated result of the authentication process.
A mobile telecommunications terminal (10), comprising:
- means for producing at least one key for decrypting messages received by the terminal;
- and
- means for sending said key to a certification authority (30) by means of a network call via a telephone network entity (20) so that said key becomes a public key.
