“Truthfulness” of IOT Sensors depends on security
A world of IOT sensors depends on the reliability of the sensors and the sensor network to deliver accurate metrics into the IOT network. This means the security technology to preserve quality and accuracy of messages, free from network disruptions (or at least detectable disruptions) and free from modification or interception by “man in the middle” attacks.
This adds a degree of complexity – including the question of how do we exchange security keys among IOT devices?
That is the topic of this “Lightweight IKEv2: A Key Management Solution for both the Compressed IPsec and the IEEE 802.15.4 Security” paper.
