Implications of controlled Access Concepts for GALILEO
There are considerations to provide certain services of the GALILEO system, i.e. high quality services or services with higher availability only to
subscribers against a fee, or to exclude non-trusted users from the service, particularly in times of tension or war. Both scenarios would require
some sort of key management to control access and specific hardware and software elements. What impact will control access schemes have
on commercial markets, and what can be done to avoid possible hindering effects for related industries?
Regarding the use of controlled access on the currently defined GALILEO services:
- Open Access Service - OAS is to be free of controlled access mechanisms giving all OAS users access to the service on a free-of-charge basis (a “public good” service). Considering the high level of interoperability with the GPS SPS, then, provided there are not excessive levies applied to receivers, there are no commercial/trade barriers which will disadvantage European industry in entering this market; the standard receiver will be a combined GPS/GALILEO receiver. Regarding European industry competitiveness, the US is clearly better equipped to capitalise on the GNSS open service market due to the scale of US industry participation in the GPS programme (including Military) and products over the last 20 years.
- Safety of Life Service - The GALILEO baseline for the SoL Service is that authentication is to be introduced rather than encryption. The rational is that an electronic signature applied to the signals will confirm the signal originated from a GALILEO satellite to overcome the possibility of spoofing, thus increasing safety. As SoL services are primarily applied in areas which are subject to international standardisation and regulation such as aviation and shipping, adoption of this scheme and the GALILEO SoL services in general requires their world-wide recognition through international bodies.
- Commercial Service – The commercial service has the capacity to carry value-added data that will be encrypted by public/private key encryption allowing the service to be operated on a commercial basis. The ranging codes remain open. This will present opportunity for EU industries and the concession contractor, but to fully evaluate the commercial potential will require significant effort.
- Public Regulated Service – Robust signal with both ranging codes and data encrypted, under Member States control. Clearly the level of security for access and denial is high and subject to security classification and is the subject of National Security. However, with an appropriate security framework PRS is thought to present a good opportunity for Europe to produce PRS only and PRS/PPS receivers. Equivalence with the US should be possible. [1]
