Gun control advocates think that smart guns will allow them to control where guns can be used, they are in for a rude shock

Marcos Portnoi and Chien-Chung Shen at the University of Delaware have a new paper entitled: "Wireless-Delimited Secure Zones with Encrypted Attribute-Based Broadcast for Safe Firearms"

From the abstract:

This work presents an application of the highly expressive Attribute-Based Encryption to implement wireless- delimited Secure Zones for firearms. Within these zones, radio- transmitted local policies based on attributes of the consumer and the firearm are received by embedded hardware in the firearms, which then advises the consumer about safe operations. The Secure Zones utilize Attribute-Based Encryption to encode the policies and consumer or user attributes, and providing privacy and security through it cryptography. We describe a holistic approach to evolving the firearm to a cyber-physical system to aid in augmenting safety. We introduce a conceptual model for a firearm equipped with sensors and a context-aware software agent. Based on the information from the sensors, the agent can access the context and inform the consumer of potential unsafe operations. To support Secure Zones and the cyber-physical firearm model, we propose a Key Infrastructure Scheme for key generation, distribution, and management, and a Context-Aware Software Agent Framework for Firearms. 

The notion is that instead of controlling gun sales, WiFi signals could be used to turn guns off in certain areas.  But does anyone think that criminals can't get around this?  Either by using a traditional gun or disabling the electronic safety on their gun.  In addition, if criminals get ahold of these Wifi signals that disable gun, it might allow them to disarm their victims before the criminals attack them.
