摘要： 综合利用数字指纹、加密、数字签名等技术,提出了一种局部环境下机密文档的分发机制。该机制不仅可以实现对文档的授权访问,而且当发现被非法分发的文档时,可以确定出非法者并提供证据。该机制设计简单,具有很好的计算和存储效率。

Abstract: A document distribution scheme for local area network is proposed based on digital fingerprinting, encryption and digital signature. Not only authorized access could be realized in the scheme, but also when an illegal document is found, the traitor could be traced with proof. The scheme is simple and with high efficiency both in computation and storage.
