Apparatus and methods for distributing and storing electronic access clients

A method for distributing access control clients, comprising:

• storing an encrypted access control client configured for a unique target device at one or more distribution locations, the one or more distribution locations not modifying the encrypted access control client;
• responsive to a request for the stored encrypted access control client, delivering the encrypted access control client;
• and
• responsive to the encrypted access control client being successfully delivered from any of the one or more distribution locations, deactivating the stored encrypted access control client.

An appliance for distributing access control clients, the appliance comprising:

• a signing appliance, the signing appliance configured to track one or more access control clients;
• a security module, the security module configured to uniquely encrypt an eSIM for a target device, the target device being configured to download only a single encrypted access control client from only a single distribution location;
• a processor;
• and
• a storage device in data communication with the processor, the storage device comprising computer-executable instructions that are configured to, when executed by the processor:
• responsive to a request for a tracked access control client from the target device, uniquely encrypt the requested access control client;
• transmit the encrypted access control client to one or more distribution locations, the one or more distribution locations which will not modify the encrypted access control client;
• and
• update the signing appliance.

A depot for distributing access control clients, the depot comprising:

• a network interface for communication with a network;
• a processor;
• and
• a storage device in data communication with the processor, the storage device comprising computer-executable instructions that are configured to, when executed by the processor:
• store an access control client that has been encrypted for a target device;
• responsive to a request for the stored encrypted access control client received from a requester device, deliver the encrypted access control client to the requester device;
• and
• responsive to the encrypted access control client being successfully delivered to the target device, delete the stored encrypted access control client.
