A resource allocator (108) receives, from a first communication unit, a request to establish secure communications with at least a second communication unit. A key identifier is retrieved by the resource allocator and transmitted to at least the second communication unit. Based upon the transmitted key identifier, the second communication unit retrieves an identified encryption key and, at least when the identified encryption key is corrupt, transmits a corrupt key indication to the resource allocator. In response, the resource allocator can assign a default key identifier for use in the secure communication. In this manner, missed communications due to encryption key failures are reduced. |
