Traffic and traveller information (TTI). TTI messages via traffic message coding - Encryption and conditional access for the radio data system. Traffic message channel ALERT C coding Ingestion-build-225643 0 % (m/m) (see Annex)1 Scope This document establishes a method of encrypting certain elements of the ALERT C coded data carried in the RDS TMC type 8A data group, such that without application by a terminal or receiver of an appropriate key, the information conveyed is virtually worthless. Before a terminal is able to decrypt the data, the terminal requires two keys. The first is given in confidence by the service provider to terminal manufacturers with whom they have a
