| Nosaukums | <p>ISO 14819-6:2006 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 keys, the information conveyed is virtually worthless.</p> <p>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 commercial relationship; the second is broadcast in the "Encryption Administration Group," which is also a type 8A group. This specification explains the purpose of the two keys and how often and when the transmitted key may be changed.</p> <p>Before an individual terminal may present decrypted messages to the end-user, it must have been activated to do so. Activation requires that a PIN code be entered. The PIN code controls access rights to each service and subscription period, allowing both lifetime and term business models to co-exist.</p> <p>The specification also describes the considerations for service providers wishing to introduce an encrypted RDS-TMC service, migrating from either a "free-to-air" service based on public "Location Tables" or a commercial service based on a proprietary Location Table.</p> <p>Finally, "hooks" have been left in the bit allocation of the type 8A group to allow extension of encryption to other RDS-TMC services.</p> |
