IoT, 5G, Cars, and Kloke

IoT devices can be traced back to World War II for the identification of friend
or foe aircraft. Radio signals were beamed and collected by RFID devices that in turn sent back an identify response. This technology is still in use today in Dallas TollTags and EZ-Passes in the northeast.

In large numbers, a tag costs just 1¢ but adding onboard encryption increased
this to 10¢, so there has always been a conflict between cost and security.
And this onboard security is really weak – the encryption on new British passport tags was cracked the same day it was introduced. This is important because if Kloke can protect simple RFID tags, it can protect all IoT devices.
