8.2 WPC Engagement

All companies selling Qi-certified or Ki-certified products must be members of the Wireless Power Consortium. All products intended to be sold as Qi or Ki certified must go through the appropriate validation, testing and certification procedures. Products are not allowed to claim compliance if they do not undergo the proper validation and test procedures. Manufacturers of Qi-certified or Ki-certified products must be in good standing with Wireless Power Consortium.

For products that require authentication, additional measures are also required. An entity that wishes to manufacture products with authentication must be licensed as a Qi-certified or Ki-certified manufacturer. Products that need to be authenticated must have a Secure Storage Subsystem (SSS) that securely stores the ECC P-256 private key. A corporation that provides the SSS must be a WPC Licensed Manufacturing Certificate Authority. Microchip has several products that meet the requirements of an SSS, and the ECC204-TFLXWPC is one such product. Microchip is a Qi-certified and Ki-certified Manufacturing CA.

Note that it is the responsibility of the manufacturer to select an SSS from a certified provider and the responsibility of the manufacturer CA to verify that a manufacturer is in good standing with the WPC.

Secure Production Provisioning Flow

The following is a typical provisioning flow for WPC production units:
  1. The customer begins development work using the ECC204-TFLXWPC.
  2. The customer opens a Microchip Sales Force support ticket for provisioned SSS.
  3. The customer provides the PTMC and Qi ID to Microchip through the support ticket system.
  4. Microchip validates the PTMC and Qi ID with the WPC to validate ownership.
  5. Once validated, Microchip generates the appropriate certificates and sets up a certificate signing request to sign the manufacturing certificate with the WPC Root CA. Microchip will initiate the key signing ceremony with WPC on behalf of the customer through the WPC automated CSR submission process once all of the WPC requirements have been met.
  6. Once the signing ceremony is completed, Microchip will generate a limited number of validation units for the customer to evaluate. Evaluation consists of verifying that the units are programmed correctly and meet all requirements of the customer.
  7. The customer provides notification to Microchip that the validation units are accepted.
  8. The customer proceeds with completion of WPC certification testing.
  9. Upon successful completion, the customer can request full production units and quantities.
