‘Quantum Cryptography’

…actually, this is a little bit misleading.

more accurately:

‘Quantum Key Distribution’

Introduction

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 Model

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

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
