A method for remotely managing a co-operative signature with a terminal, terminal, and computer readable permanent storage medium comprised in a terminal

摘要

The invention relates to a method for remote signature management of a cooperating euicc (23) with a terminal (24), the euicc (23) comprising a private key (prkeu) and a public certificate (cert-eu) consigned by its manufacturer, the public certificate (cert-eu) also comprising information enabling a signature manager server (20), without the prior knowledge of euicc (23), to decide whether he can admit to managing euicc (23), the method comprising: a. in the event of an event, establish a secure channel between the terminal (24) and the signature manager server (20) by using euicc's public certificate (cert-eu) and dedicated cryptographic services (23); B. send a subscription request from the terminal (24) to the subscription manager server (20), being considered as a subscription request by the subscription manager server (20); ç. check, thanks to the information contained in the public certificate received from euicc (23), on the signature manager server (20), whether euicc is enabled to be managed by the signature manager server (20), and if so: d . perform a key establishment procedure between the signature manager server (20) and euicc (23) using the euicc public certificate (23), this step being the registration of euicc by sm-dp; and. establishing between the subscription manager server and euicc (23) a secure channel with the keys generated in step d; f. perform through the subscription manager server (20) the subscription management request on euicc (23).
