In this paper, we investigate an important and interesting problem in a dependable secure computing system. The problem is to determine an optimal time that the secret shares should be updated on a (k, n) threshold-based secret sharing system with the proactive secret sharing (PSS) capability. In an earlier survivability study for a reconfigurable system, we developed a new definition for the survivability assessment. We extend this new definition for the survivability of the dependable secure computing system. From the survivability assessment perspective, we can easily determine an appropriate updating time for safeguarding secret information on the dependable secure computing system.
