ATN SECURITY

T he ATN SARPS have recently been extended to provide security for ATN air-to-ground and ground-to-ground communications. The ATN security approach is utilizing state-of-the-art Elliptic Curve Cryptography (ECC) for authentication of ATN communications in a constrained bandwidth environment.

BCI personnel served as editors for Sub-Volume VIII (Security) of ICAO Doc. 9705, and for the security enhancements to Sub-Volume V (Internet Communications Service). BCI's implementation of the ATN ECC schemes was instrumental in validation of the SARPS. BCI also developed the guidance material for the SARPS. BCI is currently working to specify support for confidentiality as an enhanced ATN security feature.
