In the last two posts of this series, we first introduced the governance issues in PKI and then the circular dependency between establishing trust in PKI certificates and establishing the current time on a connected device.

So let’s break that circular dependency between time and trust. The difference between trusting a person/an entity and trusting data is key here. How...

Software Defined Networking (SDN) and Network virtualization have been the disruptor technologies that were fundamental to the success of Infrastructure as a Service (IaaS) providers such as Amazon AWS, Google Cloud Compute, and Azure during the last decade. Before that, there were plenty of rival cloud providers - for most of them, changing network configurations, adding/removing machines to a network required human interaction and would take hours or sometimes days. Dedicated networking, networking...

The Diode Network enables practical distributed trust for IoT communications (and for other modalities as well). The implications of this for distributed IT infrastructure are significant. However, as the reality of distributed infrastructure emerges, other more immediate applications on the way to fully distributed infrastructure are also interesting. One of these applications is distributed wireless network operations.

For star topology wireless networks, as exists in today’s cellular communications paradigm, there are four primary things...
