Weak or expensive: the old cryptosystem and techniques don’t scale to the IoT There are basically two models for authentication of Internet relationships, one is weak (shared key) and one is expensive (public key), and neither will address the full range of identity and access requirements in the IoT. SSL (Secure Sockets Layer) and TLS […]

In the Internet of Things (IoT) there will be far more “multi-party” transactions occurring than in the Internet of old, where most transactions were intrinsically  peer to peer.  For instance, today many transactions involve a client and a server, where the client authenticates to a server for an application or service being provided by the […]
