  This work presents an application of the highly expressive Attribute-Based
Encryption to implement Secure Zones for firearms. Within these zones,
radio-transmitted local policies based on attributes of the user and the
firearm are received by embedded hardware in the firearms, which then advises
the user about safe operations. The Secure Zones utilize Attribute-Based
Encryption to encode the policies and 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 user 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.
