Patent number: 6748084Abstract: A data access control system and a method thereof is disclosed. First, the master key is divided into n subkeys to be kept by n holders, by way of secret sharing. The master key reconstruction procedure utilizes the shared secret with the subkey holders to obtain m subkeys (1<m<n) and then reconstructs the master key, using the (m,n)-threshold scheme. The system then uses the master key to access the data. Thus, m subkeys are required to reconstruct the master key in order to amend or read the data in the system.Type: GrantFiled: September 14, 1999Date of Patent: June 8, 2004Assignee: Industrial Technology Research InstituteInventors: Min-Jea Gau, Yen-Sha Chen, Wen Tsuei, Wen-Hsin Yang, Jen-Chieh Cheng
