Introduction

• Quantum Cryptography
• actually, this is a little bit misleading.
• more accurately
• Quantum Key Distribution

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
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
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
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
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
Subprojects IV

• CCC Certification acc. to Common Criteria
• Carry out preparatory work for security
  certification
• Establishment of IT security specifications

11
Point to Point QKD Simplified Component

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
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
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
