Info

The M2M solution includes the SM-SR that is not required in the Consumer solution. The SM-SRacts as a gateway from the operator and SM-DP through to the eUICC. The SM-SR holds adatabase of all the eUICCs under its control and the key sets used to manage them.Unique features of the M2M solutionA group of deployed eUICCs are managed by a single SM-SR. When there is a change ofoperator, under some circumstances there may also be a need to move the management of thatgroup of eUICCs to another SM-SR. This SM-SR swap includes transferring the group of eUICCsusing a defined SM-SR Swap procedure, and the negotiation of new cryptographic keys with eacheUICC received by the new SM-SR.SM-SR SwapUnique features of the Consumer SolutionIn the Consumer solution, the end user manages their own device and Profiles within it.The Consumer solution has the LPA in the device (or eUICC) that assists with the download ofProfiles and secures the end user interface on the device that is used for local control.All Profile downloads use IP protocols, and where applicable use the greater capacity of the deviceTCP/IP stack to reduce the communication overhead.14
As messages cannot be pushed to the device and eUICC, there is a ‘Discovery Service’ thatdevices can check from anywhere, at any time, in order to see if there are any Profiles ormanagement operations waiting to be downloaded from an SM-DP+.Differences in ComplianceUnique features of the Consumer solutionThe principles of compliance are similar for both M2M and the Consumer. The following must beverified: Production environment and process security eUICC security Functional complianceM2M was set up with clear compliance requirements and a simple process to establishcompliance.Building from the M2M implementation experience, the GSMA enhanced the compliance processfor Consumer solutions. This places greater emphasis on functional compliance, which has to bedemonstrated before the eUICC manufacturer or Subscription Management platform provider canapply for a digital certificate from the GSMA Certificate Issuer. The compliance process is up andrunning for all Consumer solution product types, with a similar scheme now being considered forM2M to strengthen the entire ecosystem.15
