Serial vault overview

Illustration of the App Store architecture, demonstrating use of a combination of public and private snaps
The serial vault serves an important function in the management of a dedicated IoT App Store

The Serial Vault is a Canonical-hosted multi-tenant web portal offered to customers. Customers may choose to set up their own dedicated Serial Vault service.

The main purpose of the Serial Vault is to provide a signed Serial Assertion to devices, which allows them to authenticate against a dedicated Snap Store. The Serial Vault also enables other functions, such as remodelling support.

The Serial Vault provides a user interface and an API to enable a device to receive digitally signed documents(assertions) that are used for authentication and authorization. An authenticated device can have access to restricted snaps from a dedicated Snap Store, providing a customised experience to the device owners.

The main assertions that are handled by the Serial Vault are:

  • Account Assertion
  • Account Key Assertion
  • Serial-Request Assertion
  • Model Assertion
  • Serial Assertion

All of these are used by the device, Serial Vault and dedicated Snap Store to verify and manage the access of a device.

In this section, we will cover a basic overview of the Serial Vault and how it is used.
