Abstract

Remote subscription management of an eUICC comprising a private key and a public certificate, the public certificate comprising information allowing a subscription manager server to decide if it can agree to manage the eUICC. The method includes: establishing a secure channel between the terminal and the subscription manager server by using the public certificate and dedicated cryptographic services of the eUICC; sendingto the subscription manager server a subscription management request; verifying, based on the information in the public certificate in the subscription manager server, whether the eUICC is entitled to be managed by the subscription manager server and, if yes: performing a key establishment procedure between the subscription manager server and the eUICC by using the eUICC public certificate; establishing between the subscription manager server and the eUICC a secure channel with the established keys; and, executing by the subscription manager server the subscription management request on the eUICC.

Dependent claims

Method for remote subscription management of an eUICC cooperating with a terminal, said eUICC comprising a private key and a public certificate signed by its manufacturer, said public certificate comprising information allowing a subscription manager server, with no prior knowledge of said eUICC, to decide if it can agree to manage said eUICC, said method comprising:

a—At the occurrence of an event, establishing a secure channel between said terminal and said subscription manager server by using said public certificate and dedicated cryptographic services of said eUICC;
b—Sending from said terminal to said subscription manager server a subscription management request, being considered as an enrolment request by said subscription manager server;
c—Verifying, based on said information in the received public certificate from said eUICC, in said subscription manager server if said eUICC is entitled to be managed by said subscription manager server and, if yes:
d—Performing a key establishment procedure between said subscription manager server and said eUICC by using said eUICC public certificate, this step being the enrolment of the eUICC by the subscription;
e—Establishing between said subscription manager server and said eUICC a secure channel with the keys generated at step—d—;
and
