A secure storage solution that simultaneously addresses the security of the Wireless Power Consortium (WPC)'s Qi 1.3 wireless charging standard is expected to enhance security performance while simultaneously resolving the inconvenience of authentication.

Microchip Technology Inc. (NASDAQ: MCHP) today announced the availability of its new industrial-grade TrustFLEX ECC608 and automotive-grade Trust Anchor TA100, combined with Microchip’s Key Provisioning Service for Qi 1.3 power transmitters.

This product is an all-in-one secure storage subsystem that includes key provisioning for consumer and automotive systems.

The Qi 1.3 specification requires the addition of a secure storage subsystem with secure key provisioning, including X.509 certificates, to cryptographically verify the source and quality of authorized power transmitters.

For example, if you install the receiver of your mobile phone into a Qi 1.3 power transmitter, you may initially only be able to charge at 5W or not be able to charge at all.

On the other hand, if the charger proves that the device is 'safe' with X.509-based ECC authentication, the phone can be safely charged at 15W, significantly reducing charging times.

Microchip is currently a WPC-authorized manufacturer Certification Authority (CA), providing pre-configured secure storage We provide subsystem solutions that not only reduce complexity and development time, but also lower the barrier to entry for technology by handling all procedures for WPC root certification authorities and key ceremonies on behalf of our customers.

Microchip is a one-stop shop for Qi 1.3 solutions, offering complete certified reference designs including application microcontrollers (MCUs), Qi 1.3 software stacks, secure storage subsystems with cryptographic libraries, and provisioning services for automotive and consumer applications.

“Microchip’s WPC Secure Storage Subsystem solution is part of our ongoing commitment to advancing the mass deployment of cutting-edge security architectures within embedded systems,” said Nuri Dagdeviren, vice president of Microchip’s Secure Products Group. “We are helping our customers in the wireless charging market more easily access this complex, yet essential, technology.”
