Abstract
Apparatus and method for synchronizing encryption keys among a cluster of security appliances and stand alone lifetime key management, LKM, appliances. The cluster includes security appliances where new encryption keys are generated and assigned to an SNS ID with an SNS CTR (counter). The security appliances inside a cluster have local sequence counters and share their keys. One security appliance is a coordinator with which the LKMs will synchronize. Each LKM also has a SNS ID and local sequence counter from which increasing sequence numbers are generated. In each security appliance in a cluster, the up-to-date stored sets of keys are organized with respect to SNS IDs and SNS CTRs associated with the other cluster members. The object keys are stored in the SNS space and a peer map associates a given peer with a given SNS ID, and version numbers are assigned and incremented when a key is modified.
