Key diversification with PHYSEC (3 min)

In this short video we explain the three current approaches to the generation, distribution and storage of cryptographic keys. The first approach relies on pre-programmed keys, the second approach employs "public key infrastructures" to allow individual key generation by each device. The new apporach (PHYSEC-KeyGen software) starts with pre-programmed keys and automatically diversifies these in the field based on local context information.

With these attributes, the third generation of solutions offered by PHYSEC GmbH combines all the advantages (simplicity, high resilience) of both prior generations while sharing none of their weaknesses.

Secure Pairing with PHYSEC (1:30 min)

In this short video Christian shows how easy it is to pair an embedded device with a router with the help of a smartphone. For this, he uses a demonstrator app we have developed for the smart phone.

The router, the pairing hardware and the embedded device (a TI cc2531-based hardware module with an 8-bit processor) are all running PHYSEC-ProPair to enable pairing functionality. Furthermore, we have also integrated PHYSEC-KeyGen into the router and embedded devices so that keys are always regenerated.

The combination of both solutions makes authenticating devices and distributing keys easy and secure.

Sicherheitslösungen der dritten Generation für das Internet der Dinge (35:30 min)

Ressourcenarme, drahtlos kommunizierende Kleinstgeräte sind günstig, werden in großen Stückzahlen angeboten (bspw. Funkmodule mit 8-Bit-MCU) und finden zunehmend Verwendung im Internet der Dinge. Zeitgleich entwickeln sich kriminelle „Geschäftsmodelle“ weiter (Sabotage, Erpressung), bei denen „Online-Mafias“ schon heute mehr Umsatz machen als ihre Vorgänger in der realen Welt. In diesem Spannungsfeld rücken die Sicherheitsbedürfnisse neuer Applikationen zunehmend in den Fokus.

Wir zeigen in diesem Vortrag, welche Sicherheitslösungen auf günstigen MCUs überhaupt möglich sind und worauf geachtet werden sollte. Weiterhin stellen wir wissenswerte Vor- und Nachteile der ersten Generation von Sicherheitslösungen (Verschlüsselung mit festen, vorverteilten Schlüsseln) und der zweiten Generation (Verschlüsselung mit PKI-basierten Schlüsseln) vor und vergleichen diese mit neuen Ansätzen der dritten Generation. Zuletzt wird in diesem Vortrag eine kurze Übersicht weiterer Problemstellungen gegeben, für die neuartige Lösungsansätze existieren.
