一种基于一般接入结构的抗欺骗秘密共享体制

An Anti-cheating Secret Sharing Scheme Based on a General Access Structure

秘密共享体制是适用于保管极其重要信息的一种安全协议,其最大威胁是欺骗攻击,构造抗欺骗攻击的秘密共享体制具有重要意义.本文给出了一种有效构造方法,对于一般的接入结构也可以构造出抗欺骗攻击的体制,并且利用纠错编码的思想,使得体制的信息率有较大的提高.

Secret sharing scheme is a kind of security protocol, which is suitable for keeping secret the most important information. But it may mostly be vulnerable to the attack by cheating. Therefore, it is very important to construct a scheme, which is able to withstand the attack of cheating. In this paper the authors present an effective method of construction. It is a way to construct an anti-cheating scheme on any given access structure. By the ideal of rectify-error coding,it has been significantly improved the information rate of the scheme.
