Combinatorial Problems in Cryptography and Communication

这笔赠款旨在支持以色列理工学院的Tuvi Etzion教授访问伦敦大学的皇家霍洛威。Etzion教授是编码理论和序列设计方面的专家，这两个数学领域始于20世纪40年代，随着数字通信和存储的发展，其重要性急剧上升（其中应用于经由电话线、移动的电话、无线计算和深空探测器通信的计算机）已经变得无处不在。他的研究为这些应用中减少传输错误的技术奠定了基础，并与光存储介质等新领域相关。皇家霍洛威在密码学（制作和破解密码的科学）方面拥有世界领先的团队。虽然密码学通常被认为是其在保护消息机密性方面的传统角色，但还有其他应用，包括验证消息（例如核实电脑是否获授权进行网上交易），使密码技术对现代世界变得至关重要。是次访问的目的是就我们各自的专业范畴交换意见和问题，希望在解决单靠一个领域的技术无法解决的问题方面取得进展。

This grant aims to support a visit by Prof. Tuvi Etzion, from Technion, Israel, to Royal Holloway, University of London.Prof. Etzion is an expert in coding theory and sequence design, areas of mathematics that began in the 1940s and which have exploded in importance as digital communication and storage (with applications to computers communicating via phone lines, mobile phones, wireless computing and deep space probes amongst others) have become ubiquitous. His research underpins techniques to reduce transmission errors in these applications, and has relevance to new areas such as optical storage media.Royal Holloway has a world leading group in cryptography, the science of making and breaking secret codes. Though cryptography often thought of in terms of its traditional role in preserving the confidentiality of messages, there are other applications which include authenticating messages (verifying that a computer is authorised to make an online transaction, for example) which have made cryptographic techniques vital to the modern world.The aim of the visit is to exchange ideas and problems in our respective areas of expertise, in the hope that progress will be made in solving problems that cannot be solved using techniques from one area alone.
