講演題目: The Rise and Fall and Rise of Combinatorial Key Predistribution
講演者: Prof. Keith Martin(Royal Holloway, University of London, UK)
Prof. Keith Martin (Royal Holloway, Univ of London, UK.) が来日される機会に共通鍵暗号を利用する際に基本となる鍵配送に関して、最近発表された効率的な配送方式についてご講演をお願いしました。是非ご参集ください。
アブストラクト:
There are many applications of symmetric cryptography where the only realistic option is to predistribute key material in advance of deployment, rather than provide online key distribution. The problem of how most effectively to predistribute keys is inherently combinatorial. We revisit some early combinatorial key predistribution shemes and discuss their limitations. We then explain why this problem is back “in fashion” after a period of limited attention by the research community. We consider the appropriateness of combinatorial techniques for key distribution and identify potential areas of further research.
