DES加密算法在秘密共享中的应用

The Implementation of DES in Secret Sharing Scheme

秘密共享思想提出后,经过几十年的发展已经出现了很多不同方案、模型等。本文根据秘密共享的特性提出了一种基于对称密钥系统的秘密共享方案。该方案解决了一些秘密共享现有的问题的,尤其是可验证性。存储在密钥分发者的信息都是加密后的密文,因此,其抗攻击的强度就是使用的加密算法的强度。通过简单C++程序实现这一方案。对方案的可行性进行分析。

It has been decades since the idea of secret sharing first introduced . Various kinds of schemes and models have been put forward based on the idea through the development of the decades. In this paper, introduce a new scheme based on the symmetric cryptosystem according to the characters of the idea. This scheme solved some exiting problems of the idea, especially verifiability. The data stored in the server is encrypted, so that, the intensity of invulnerability is based on the intensity of the cryptosystem. A simple C＋＋ program is made for the implementation of the scheme. Analyze the feasibility of the scheme.
