摘要
扩展半可信第三方的思想,提出"条件可信第三方"的概念,即任意第三方在满足限定条件的前提下,要么是可信的,要么行为是可验证的.同时,结合离线第三方的思想,提出基于离线条件可信第三方的不可否认协议.相比于原有协议,新的协议进一步减少了对可信第三方的依赖.
The idea of conditional TTP was developed on the basis semi-trusted TTP. The term of 'conditional trusted third party' means that on the condition of third party satisfying the pre-conditions, if he behaves right, then he is trusted, else his behavior can be checked by participators of the protocol. A new protocol adopting off-line and conditional TTP was put forward. Compared with available non-repudiation protocols, this one progresses further in reducing intervention of TTP in fair exchange.
