Smart tech is the smart choice so long as it’s well-engineered

A few weeks ago, we learned about Amazon’s ambitious plans for Amazon Key. Amazon Key is a solution that allows Amazon delivery people to leave packages inside the home rather than outside the door. They do this by converting traditional door locks to smartlocks, which can be accessed by Amazon when needed. A camera is included to monitor the drop offs. I expect that Amazon has done their market research; They know that some consumers will prefer the risk of giving Amazon access to their home over the risk that packages could go missing. Additionally, the service avoids the inconvenience of having to wait at home for deliveries  This is the same tradeoff between operational efficiency and security that Sera4 solves for industrial infrastructure.

Smartlock security was put to the test at last year’s DEFCON conference, where hackers try to break security. Twelve out of sixteen tested smartlocks were hacked within 15 minutes using simple digital equipment. I had hoped that this would send a message to our industry to take security more seriously. Unfortunately, Amazon’s newly-released smartlock system has already been hacked. Although the current vulnerabilities don’t show how to unlock someone’s house without authorization, the security holes destroy trust in the video surveillance that is a core component of the Amazon Key system. I don’t feel confident to put this on my front door. I doubt anyone wants a lock on their house that let hackers walk in, no matter how “smart” the feature list appears.

Designing secure smartlocks is not easy. It requires both physical security and logical security. People have been designing for physical security for centuries. We’ve largely figured out how to do that. Designing for secure wireless control is a new area, where many designers are still just learning. It’s not surprising that they overlook things.  Security is Sera4’s specialty. Since we don’t aim to get our products in residential front doors, I hope that someone else brings secure residential smartlocks to market soon. If not, adoption is going to be very slow, or we’re going to have a lot of unexpected burglaries in the near future.
