A Share Assignment Method to Maximize the Probability of Secret Sharing Reconstruction under the Internet

摘要

The use of Internet for various business appli- cations and resource sharing has grown tremendously over the last few years. Internet security has become an important issue for both academic and industrial sectors. Much related network security research has been conducted such as user authentication, data confidentiality, and data integrity. In some applications, a critical document can be divided into pieces and allocated in dif- ferent locations over the Internet for security access concern. To access such an important document, one must reconstruct the divided pieces from different locations under the given Internet environment. In this paper, a probability model for reconstruct- ing secret sharing and algorithms to perform share assignment are presented. Also, an evaluation algorithm to measure the prob- ability of secret sharing reconstruction is proposed. Illustrative examples and simulation results are provided to demonstrate the applicability of our method.
