Information
This workshop aims to bring together experimentalists and
theoreticians to solve some of the problems in implementing and
developing cryptography from storage imperfections.
The difficulty of
storing quantum information has first been captured by the
bounded-quantum-storage model and recently by the more general
noisy-storage
model. These models allow for the implementation of
secure two-party
computation such as secure password-based
identification
if we are willing to make the physical assumption that a cheating
party only has access to an imperfect quantum-storage device.
Otherwise, the cheating party may be all powerful.
To execute the protocols, honest parties require no quantum storage at
all.
The quantum part of the proposed protocols is identical to
BB84-based quantum key distribution (QKD), with a different form of
classical post-processing. Yet, due to the different nature of the
applications, we face several experimental and
theoretical challenges
that set it apart from QKD. These protocols are particularly
interesting at short distances where one would like to have a small,
low-power, hand-held device that could be used for
identification.
Experimental and theoretical questions thus include:
- Can we build a portable device suitable for this task?
- What security parameters can we hope to achieve in a practical implementation?
- What are the best noise models for quantum memories?
- Can we construct more efficient protocols, and extend the class of memories for which we can obtain useful security parameters?
