Truphone SM-DP SM-SR solution for M2M
The Remote SIM Provisioning for M2M is a server driven solution to provision and remotely manage operator profiles on the eUICC, whereas the eUICC is a secure element that contains one or more of these operator profiles. The solution is then organized around 3 elements: the SM-DP (Subscription Manager - Data Preparation), the SM-SR (Subscription Manager - Secure Routing) and the above eUICC.
The SM-DP is responsible for preparing, storing and protecting operator profiles (including the operator credentials for cellular network attachment). It also downloads and install the operator profiles onto the eUICC through the SM-SR.
The SM-SR is then responsible for managing the status of the operator profiles already downloaded on the eUICC (the operator profiles can be enabled, disabled, deleted, using the SM-SR functionalities). It also secures the communications link between the eUICC and SM-DP for the delivery of operator profiles. The SM-SR holds a database of all the eUICCs under its control and the key sets used to manage them.
