A method for allowing a network service provider (SP) to control the distribution and execution of a programming code (FS) on a network access device, by means of a ciphered signature associated to the programming code (FS), wherein: - the ciphered signature (FK) is generated by means of a private key (Kpr) retained by the service provider; and - a public key (Kpub), corresponding to the private key (Kpr) of the service provider, is stored on smart cards (SC) distributed to users and is read by the network access device for verifying the validity of the ciphered signature (FK) and the integrity of the associated programming code (FS). |
