Proper implementation of IoT authentication can have a number of beneficial effects on IoT security. Taking this approach though, can be challenging as making the wrong choice of authentication method can increase risk exponentially. There are many other best practices that can be employed when contemplating an IoT authentication strategy. The blog that follows does an excellent job of detailing all the methods that can be used when designing an authentication approach to IoT security.
In the case of certificates, HSM, TPMs, and X.509 applications, the main challenge is to prove possession of the key without revealing the key’s private portion.
IoT authentication is a model for building trust in the identity of IoT machines and devices to protect data and control access when information travels via an unsecured network such as the Internet.
Strong IoT authentication is needed so that connected IoT devices and machines can be trusted to protect against control commands from unauthorized users or devices.
Authentication also helps prevent attackers from claiming to be IoT devices in the hope of accessing data on servers such as recorded conversations, images, and other potentially sensitive information.
There are several methods by which we can achieve strong authentication to secure IoT device communications:
