Securing the global Airspace System via identity-based security

• To globally deploy new communications technologies into the GAS those technologies must meet all the requirements of the “Able List”. • The GAS currently consists of a variety of communications links, often quite old such as Very High Frequency (VHF) analog radios with limited bandwidth capability. • New technologies such as Gatelink and AeroMACS offer greater capability, greater band- width, better security and potential cost savings. - These systems will not be deployed if the cost of deployment and management outweighs the benefits. • Identity-based security with single certificate sign-on for system access along with the capability of managing QoS policy for diverse systems in a centralized location has the potential to ensure a smooth, evolvable, scalable, manageable, affordable deployment. • Modern telecommunications networks have shown this to be possible for single communication technologies types (e.g. LTE and WiMAX). • The tools and architectures exist.
