An Open Source Bid to Encrypt the Internet of Things
IoT is a security hellscape. One cryptography has a plan to make it a little bit less so.
End-to-end encryption is a staple of secure messaging apps like WhatsApp and Signal. It ensures that no one—even the app developer—can access your data as it traverses the web. But what if you could bring some version of that protection to increasingly ubiquitous—and notoriously insecure—Internet of Things devices?
The Swiss cryptography firm Teserakt is trying just that. Earlier this month at the Real World Crypto conference in New York it introduced E4, a sort of cryptographic implant that IoT manufacturers can integrate into their servers. Today most IoT data is encrypted at some point as it moves across the web, but it’s challenging to keep that protection consistent for the whole ride. E4 would do most of that work behind the scenes, so that whether companies make home routers, industrial control sensors, or web cams, all the data transmitted between the devices and their manufacturers can be encrypted.
