Asmuth-Bloom方案的抗欺骗性能

The Anti-cheating property of the Asmuth-Bloomsecret sharing system

MartinTompa和HeatherWoll证明Shamir门限方案在防止主动欺骗的情况下是不安全的,他们的攻击被称作Tompa Woll型攻击.文中指出Asmuth bloom门限方案在防止强欺骗的情况下也是不安全,一个小的改进可在保持与原方案相同的安全性和有效性的情况下,防止强欺骗.

Martin Tompa and Heather Woll demonstrated that Shamir's Scheme is not secure against cheating and this attack is called Tompa-Woll attack. In this paper, we show that the Asmuth-Bloom's System is also not secure against strong cheating. A little modification of this scheme retains the security and efficiency of the original scheme and is secure against strong cheating.
