Abstract
An improved technique involves protecting a set of resources in a distributed computer system by scheduling epochs for replacing keys that have a variable duration. Along these lines, a Variable Epoch Scheduler (VES) generates schedules of key updates for a set of players in the distributed system such that at least two epochs in the schedules have different durations. For example, the epoch durations within a schedule may vary, or the epoch durations for different players may be different. At the end of each epoch, the VES notifies the distributed system to update the key identified in the schedule as corresponding to that epoch.
