Zero Touch Provisioning AWS IoT Kit

Microchip's Amazon Web Services (AWS) IoT kit for rapid prototyping of secure IoT applications

Image of Microchip's Zero Touch Provisioning AWS IoT Kit The AT88CKECC-AWS-XSTK-B Zero Touch Secure Provisioning Kit from Microchip Technology helps designers to quickly and securely develop IoT devices that are in compliance with the AWS security regulations. These regulations state that a device must use mutual authentication with a remote server to be authorized on the AWS cloud. Meanwhile, a robust authentication must also ensure a complete isolation of the system credentials such as private keys from the application core to avoid leaving backdoors opened to software loop holes. In addition, the software is as secure as the user's skillset is in security. Human users and software are one of the easiest targets for a hacker as they are the least reliable elements. Incorporating Microchip pre-configured ATECC508-MAHAW or ATECC508ASSHAW CryptoAuthentication devices into a system is a very secure method to connect to the AWS IoT service. This means the handling of certificate and private key manipulation to Microchip secure provisioning factories in addition to keeping secrets away from software and users.

The devices are pre-configured but not provisioned out of the box. Start with the upgraded Zero Touch Provisioning Kit for AWS IoT Version B and benefit from the new provisioning scripts (Python based) and AWS IoT account configuration scripts (using CloudFormation). This Version B of the kit comes with an easier onboarding process to generate certificates and provision them into the CryptoAuthentication device using Python scripts. In addition, the user will have access to a CloudFormation script to generate a web UI reflecting the I/O of the kit and utilize it as a foundation to develop virtually any sensor based use cases. In addition to the ATECC508AMAHAW, the kit includes a Cortex®-M4 ATSAMG55 and Wi-Fi ATWINC1500 using FreeRTOS and the ATWINC1500 integrated TLS stack. The AT88CKECC-AWS-XSTK-B kit enables customers to quickly and efficiently development secure IoT applications.
