Simplify hardware-based IoT security with industry’s first pre-provisioned solutions for deployments of any size

Microchip Trust Platform for the CryptoAuthentication Family

With a minimum orderable quantity of just 10 units, Microchip’s new Trust Platform provides hardware-based secure key storage for low-, mid- & high-volume deployments.

As numbers and types of connected devices proliferate, market fragmentation and IoT (Internet of Things) security vulnerabilities have created significant challenges for developers. Hardware-based security is the only reliable way to protect secret keys from physical attacks and remote extraction, but extensive security expertise, development time and costs are required to configure and provision each device. With companies producing anywhere from hundreds to millions of connected devices each year across the globe, scalability of architecture is a major barrier to deployments.

Hardware-based IoT security for all
Manufacturers typically have only been able to support configuring and provisioning for high-volume orders, leaving companies with low- to mid-sized deployments with low performing security options. To address this need in the mass market, Microchip Technology has introduced the industry’s first pre-provisioned solution that provides secure key storage for low-, mid- and high-volume device deployments using its ATECC608A secure element. Microchip’s Trust Platform for its CryptoAuthentication™ family enables companies of all sizes to easily implement secure authentication.

Microchip’s Trust Platform consists of a three-tier offering, providing out-of-the-box pre-provisioned, pre-configured or fully customisable secure elements, allowing developers to select the platform best suited for their individual design. As the first solution to provide ready-to-go secure authentication for the mass market, the first tier – Trust&GO – provides zero-touch pre-provisioned secure elements with a minimum orderable quantity (MOQ) as low as 10 units. Device credentials are pre-programmed, shipped and locked inside the ATECC608A for automated cloud or LoRaWAN™ authentication onboarding. In parallel, corresponding certificates and public keys are delivered in a 'manifest' file, which is downloadable via Microchip’s purchasing e-commerce store and select distribution partners.

In addition to saving up to several months of development time, the solution significantly simplifies provisioning logistics, making it easy for mass market customers to secure and manage edge devices without the overhead cost of third-party provisioning services or certificate authorities.

Need more customisation?...
With the ability to authenticate to any public or private cloud infrastructure, Microchip’s Trust Platform is also flexible and customisable. For customers who want more customisation, the programme includes the TrustFLEX and TrustCUSTOM platforms.

The second tier in the program, TrustFLEX, offers the flexibility to use the customer’s certificate authority of choice, while still benefiting from pre-configured use cases. These use cases include baseline security measures such as Transport Layer Security (TLS) hardened authentication for connecting to any IP-based network using any certificate chain, LoRaWAN authentication, secure boot, Over-the-Air (OTA) updates, IP protection, user data protection and key rotation. This reduces the time and complexity involved in customising the device without requiring customised part numbers.

For customers who would like to entirely customise their designs, the third tier in the program – TrustCUSTOM – provides customer-specific configuration capabilities and custom credential provisioning.

The uptick in successful attacks on software-based security solutions underscores the need for companies to adopt industry best practices, including isolating private keys in secure elements,” said Nuri Dagdeviren, Vice President of Microchip’s Secure Products business unit. “Microchip’s Trust Platform makes hardware-based security simple and cost-effective for companies of all sizes to implement, removing the barriers traditionally associated with configuring and provisioning devices.

Microchip worked with Amazon Web Services (AWS) to enable a straightforward and simplified onboarding process into AWS IoT services for products designed with all variants of the Microchip Trust Platform. 

The ATECC608A provides Common Criteria Joint Interpretation Library (JIL) “high”-rated secure key storage, giving customers confidence that devices implement industry-proven security practices and the highest level of secure key storage. With hardware-based root of trust storage and cryptographic countermeasures, the device protects against the widest classes of known physical attacks. Microchip’s secure manufacturing facilities safely provision keys, ensuring that keys are never exposed to any party during provisioning or the lifetime of the device.


Development tools
The ATECC608A can be paired with any microcontroller and microprocessor. For rapid prototyping of secure solutions, designers can use the Trust Platform Design Suite, which includes:
•    A guided 'use case tool'
•    Executable Python tutorials running on Jupyter notebooks
•    C code examples for each use case
•    A 'secret exchange' utility
•    The Trust Platform hardware development kits
