The buttons on the Key Fob available for purchase with the Almond+ appear to be designed for arming and disarming a security system. Does the Key Fob support encryption? Is there anything preventing someone from sniffing/capturing a transmission from the Key Fob and cloning the signal to disarm a system built using the Key Fob?

As it's a ZigBee key fob it's using standard ZigBee encryption i.e. 128-bit.

But Zigbee on its own does not enforce full encryption. This page describes how encryption enabled and non-encrypted Zigbee nodes can interact with each other. http://www.digi.com/support/kbase/kbaseresultdetl?id=2214

I'm having the software team check it, but the reply I got from them seemed to suggest the key fob is using encrypted signalling.

Thanks for looking into it. I know with Zwave, some devices such as locks have a higher level of security than other devices such as temperature sensor. Since Zigbee is not as popular, I'm not finding as much information about it. I did find this article http://www.sensor-networks.org/index.php?page=0903503549 which goes into a lot of details but still does not tell me how do I know if a given device is using the highest level of security.

I've sent an email to the manufacturer as well to check with them, as I guess they can give us a definitive answer.

Any update on this? I see we need to finalize our selection by Sunday.

Sorry, yes, the communication is encrypted, just as it would be with a door lock for example.
