Abstract
A first intermediate key management system (KMS) server of a distributed KMS receives a key lookup service (KLS) query from a KMS client for determining an identity of KMS server(s) that are capable of performing a first operation with a first managed key. The first intermediate KMS server is one of the intermediate KMS servers of the distributed KMS. The first KMS server determines the identity of one or more of the KMS servers that are capable of performing the first operation with the first managed key. The first KMS server transmits a KLS response to the KMS client that includes the identity of the KMS server(s) that are capable of performing the first operation with the first managed key.
