How can we trust the internet of things?

Originally posted on Gigaom:

The internet of things (IoT) promises us a world of intelligent fridges that automatically order groceries from the supermarket, smartwatches that relay our blood pressure to the doctor, and connected ovens that preheat when they see that we’ve left work. But amid all the breathless speculation about our connected future, little attention is being given to how we will ensure that the internet of things is safe.

Cisco predicts that by 2020 there will be 50 billion connected devices around the world, all communicating with a variety of systems, databases, people and machines. This represents a hugely expanded network of potential vulnerabilities. Meanwhile, the nature of IoT communications makes the consequences of a successful attack even more harmful.

Who are you, really?

We need the ability to establish the true identity of any device that connects to the internet, and any system or person that communicates with a device. Without…

Mramor je zrnate (granoblastične) strukture i
homogene teksture, sadrži kalcit i/ili dolomit, a
od primarnih nečistoća u sedimentu nastaju

se reže, obrađuje i polira. U likovnoj umjetnosti
je cijenjen zbog svoje mliječne boje,
poluprozirnosti i toploti koja podsjeća na ljudski dodir.
U antici najznačajnije građevine i skulpture
nastale su od čuvenog mramora s otoka Para
(grčki: Parosa) i brda Pentelikona.
U Italiji je cijenjen mramor iz Carrare od kojeg
je izrađen i Michelangelov David. Brački mramor (pučiški kamenolom) je cijenjen
u cijelome svijetu te su mnoge građevine
