Abstract
A method for distributing updates for a key is described. One or more update requests are received per unit of time. The number of received update requests per unit of time is multiplied by a maximum update period to estimate the number of active nodes in a group. The total number of received update requests per unit of time is determined. An amount representing additional update requests per unit of time is obtained from the difference between the total number of received updates and a determined maximum. A minimum update period for a group of nodes is determined.
