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; sending to 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.
