2. 2 Integrated Project FP6-2002- IST-1 -506813 Unit D4: ICT for Trust and Security Objective: „Towards a global dependability and security framework“ Duration: April 2004 – April 2008

3. 3 Consortium Co-ordinator: ARC Seibersdorf research (Vienna) 41 Teams: 25 from Universities 4 from National Research Centers 8 Multinational Enterprises 4 SMEs …from 11 European Countries: A, B, CH, CZ, D, DK, F, I, RU, S, UK Funding: 11.300.000 Euros

4. 4 ‘Quantum Cryptography’ …actually, this is a little bit misleading. more accurately: ‘Quantum Key Distribution’ Introduction

5. 5 QKD, what is it? Quantum Key Distribution is simultaneous generation of identical bit sequences in two distinct locations with quantum physical methods Quantum technology guarantees unconditional security QKD enables the implementation of a perfectly secure secret channel

6. 6 Project Goals Make QKD ready for practical application Make physical devices ready for practical application Provide necessary interfaces for the integration into existing applications Develop conceptual design for networked infrastructures

7. 7 Subprojects I COM – Components –Development of advanced Sources and Detectors Experimental QKD - 4 Teams / different Technologies: –Zeilinger/Vienna Entangled Photons –Ribordy/Geneva Weak Pulses –Grangier/Paris Continuous Variables –Weinfurter/Munich Free Space

8. 8 Subprojects II QIT – Quantum Information Theory –Evaluation of different QKD technologies –Development of quantum protocols SEC – Security and Cryptography –Classical security analysis –Development of cryptographic algorithms and models

9. 9 Subprojects III SYS – System Integration –Market analysis –Integration of QKD into existing systems –Definition of Interfaces NET – Network Architecture –Network design and simulation –Development of QKD based infrastructures –Definition of Network Standards

10. 10 Subprojects IV CCC – Certification acc. to „Common Criteria“ –Carry out preparatory work for security certification –Establishment of IT security specifications

11. 11 Point to Point QKD Simplified Component Model

12. 12 Network Architectures I SecLink –Point to Point –For banks, ATMs, governmental institutions SecMAN (Metropolitan Area Network) –All nodes belong to one organisation –All end users have QKD channels to some network member –For big companies with many urban outlets

13. 13 Network Architectures II SecWAN –Secret is distributed over many paths –Attacker has to control at least one node in each path –For trusted centers, users with special privacy needs

14. 14 Conclusion: Importance of Standardisation Standardisation of ‘internal’ interfaces –Achieve interoperability of QKD components of different manufacturers Standardisation of ‘external’ interfaces and network infrastructures –To make applications compatible with different QKD systems –Provide applications standardised access to QKD based infrastructures
