Message security for ground-to-ground messaging is vital and lacking

Together with seven other companies involved in the Aviation ground to ground messaging market, Isode have today issued a press release calling on Aviation Authorities, currently planning their transition to messaging based on ICAO's AMHS standard, to incorporate into those plans AMHS message security features provided for by the 'Extended' ATS Message Service.

The Extended ATS Message service provides for two security services to be integrated into the application:

1. Content integrity - ensuring that a message has not been tampered with in transit.
2. Origin authentication - enabling the recipient to verify that the message comes from the claimed sender.

Both of these services are based on the widely used X.509 digital signature standard supported by public key infrastructure (PKI).
