If you buy a $5 wifi-enabled lightbulb, there's a good chance it'll have an ESP32 (which can do most modern SSL) or an ESP8266 (which is short on memory, and so might use SSL with a preshared key, "TLS-PSK")
On the other hand, if $5 devices seem a bit expensive to you, because you think $0.01 parcel labels will be part of the internet of things in the future, I suppose you might be interested in this new NIST algorithm?
- contact9879 4y agoI understand that, but these devices, how will they access the "internet"? They need to talk to a router or other device that is then connected to the internet. What protocol would they use to connect? Or is this for just "near-me area networks" that need to communicate with each other? I never really considered key fobs or pacemakers as IoT devices because they don't actually connect to the internet.
- eternityforest 4y agoPacemakers definitely need security though. Although I don't see why they can't use AES like everything else.
- spelunker 4y agoYes, some IoT devices communicate over WiFi, but others will talk to a gateway or hub over something else, such as BLE or Zigbee. I guess those could be the targets for this.
