Since it’s launch back in 2015, AWS IoT has been a hit with users worldwide. Today AWS is making this service even more flexible by introducing just-in-time certificate registration for devices.
In short, you no longer have to create a database to keep track of certificates and their matching devices. Instead, you register the device with a certificate during their initial communication. This makes it simple to create a system for millions of devices.
To begin with, you must have a CA (Certificate Authority) certificate. Then the process goes like this:
- You will register and activate the CA certificate.
- Use this certificate to create and sign the certificates you will use per device.
- Let the device present the certificate to AWS and then activate it.
- Finally, use an AWS Lambda function to notify you when a new certificate is present to AWS. It can also activate the certificate and handle any registration or initialization.
You can learn more about this update from the documentation. If you would like to set up this functionality (or something similar) for your organization, contact us today at PolarSeven.
