一种基于布尔代数的秘密共享方案

Secret Sharing Scheme Based on Boolean Algebra

秘密共享方案是在n个参与者之间共享秘密k的方法。将布尔代数中的与或逻辑引入秘密共享而提出的新方案运算速度快,并具有灵活的自适应能力和良好的可扩展性,便于软件编程和硬件固化,可以与经典的加密方法紧密结合,以提高其安全性。

A secret sharing scheme is a method of sharing a secret k among a set of n participants. Shares are renewed in a simple way in the scheme with the conjunction and disjunction logic in Boolean algebra, so it proves sound flexible and extensible and its speed is fast. The scheme can be combined with the classical encryption methods to improve its safety, which is easy to be encoded with software and implemented with hardware.
