Combinatorial Problems in Cryptography and Communication

这项资助旨在支持以色列理工学院的Tuvi Etzion教授访问伦敦大学皇家霍洛威学院。Etzion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（通过电话线、移动电话、无线计算和深空探测器等应用于计算机通信）变得无处不在，它们的重要性得到了爆炸式的发展。他的研究支持了在这些应用中减少传输误差的技术，并与光学存储介质等新领域相关。皇家霍洛威拥有世界领先的密码学团队，这是一门制作和破译密码的科学。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，包括对消息进行身份验证（例如，验证计算机是否被授权进行在线交易），这使得密码学技术对现代世界至关重要。这次访问的目的是交流我们各自专业领域的想法和问题，希望在解决无法单独使用一个领域的技术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.
