Abstract
Apparatus and method for synchronizing objects, e, g., encryption key objects, between pairs of appliances, particularly lifetime key management (LKM) appliances. Each LKM has a local sequence counter where increasing sequence numbers are generated and applied to objects. A peer counter is used to indicate the sequence number of an object synchronized from a peer appliance. When two appliances are synchronized, only those new objects with sequence numbers at least equal to or higher than that within the other appliance are transferred. When synchronized to each other, each appliance will have an up-to-date stored set of objects for all of the appliances in the group. Each object has a unique identification number that are compared to eliminate duplicate objects. During synchronization, if unique identification numbers match between a newly received object and a previously stored key, version numbers may be used to determine which object the receiving appliance should store.
