A story of chip builders, key factories, fleet commanders, and the team that runs the robot network
Consumer eSIM uses 5 helpers. But the M2M robot network needs 6! Why? Because when you're managing 10,000 robots across the world: with no screens and no users: you split the big jobs into smaller, safer pieces.
The Chip Builder (EUM) manufactures the tamper-proof vault chip and installs the robot's secret identity at birth. The ID Authority (CI) is the passport office: it signs the master badges everyone trusts. If the CI didn't sign it, nobody respects it!
The Key Factory (SM-DP) crafts secret keys locked to one specific robot and encrypts them so nobody can peek: not even the Commander. The Commander (SM-SR) is Mission Control: the only one with the radio frequency to talk to the robots. Together they deliver sealed orders!
The Fleet Owner (Operator) is the mobile network company that orders keys and decides when robots switch. The Fleet Manager (M2M SP) handles day-to-day operations: like a logistics company managing trucks but not owning the fuel stations. Six helpers, one mission!
The split between Key Factory (SM-DP) and Commander (SM-SR) is unique to SGP.02. In consumer eSIM, they're combined into one role (SM-DP+). But splitting them lets a fleet owner change Key Factories without changing Commanders: or switch Commanders without touching any keys!
