Microchip and The Things Industries (TTI) are in cahoots together and they want to bring in developers to their secure circle. The idea is to provide secure authenticated communication as well as secure deployment.
The solution is built around Microchip’s ATECC608-MAHTN-T secure element chip (. This I2C device is a cryptographic coprocessor with hardware-based secure key storage. It can store up to 16 keys or certificates.
Typically, a user generates a public/private key pair for use in a public key infrastructure (PKI) and registers the public key with TTI. The private key is programmed into a LoRa device. Communication between the TTI servers on the internet and the device can be authenticated. The process is a bit involved and works for an individual developer, but this is too cumbersome when deploying hundreds to millions of devices.
the two companies have made the process easy regardless of the number of devices a company plans to deliver. The secure key provisioning system starts with ATECC608A-MAHTN-T chips that are programmed at the factory with private keys that have a matching Manifest file containing the associated public key information (Fig. 2). The Manifest file is signed by Microchip and can be recognized by TTI when it receives the file. It then adds the key to its secure join server database. At this point, the device with the secure element can communicate securely with the secure join server.
