To make adding hardware secure key storage easier, the secure element is paired with The Things Industries' (TTI) join server service for turnkey secure authentication. The corresponding AES128 authentication keys are also hosted and protected in TTI’s managed join servers. Through a claim procedure via the TTI portal, the protected keys in the secure element are “claimed” and then owned by the company. This process simplifies the cumbersome unsecure provisioning practice used without secure key storage. This join server is completely agnostic to the network server and/or application server providers to preserve business scalability by leaving freedom of choice to the architects. Flexibility doesn’t stop here, the ATECC608A-MAHTN secure element is a microcontroller-agnostic solution that adds true hardware secure key storage to any LoRa-connected products.
How to build a secure provision workflow and strengthen authentication to TTI’s join server. Manipulating application and network server keys is not only a daunting process but also opens backdoors in LoRaWAN connected products. Microchip’s secure element, bundled with TTI’s join server service, helps simplify the provisioning process and secures the keys, not only in the deployed system but also throughout the entire supply chain.
