- Abstract
- The North American SynchroPhasor Initiative Network (NASPInet) aims to provide a secure and reliable communication infrastructure for sharing phasor measurement unit (PMU) data among utilities, balancing authorities, reliability coordinators and other pow- er grid entities. Since the data is secured using cryptographic primitives such as encryp- tion and message authentication codes, it is critical to ensure fault tolerance of the key management infrastructure that the cryptographic primitives rely on. Since an entity might be sharing its data with multiple other power grid entities, group cryptographic primitives are more efficient and thus the keys must be distributed and managed among a group of authorized entities. To make group key management (GKM) fault tolerant, we must eliminate its single point of failure – the key distributor (KD). To ensure that the system can keep running even if the KD experiences failure, we maintain its replicas, which can replace it whenever needed. If not managed efficiently, replication can lead to problems like lack of consistency between replicas, deadlocks, and decreased throughput of operations. Hence, it is necessary to coordinate operations. Instead of performing co- ordination from scratch, it is much more efficient to make use of a coordination service that has proven to be successful in doing so for other applications. In this thesis, we pro- pose the design of an interface that enables the group domain of interpretation (GDOI) group key management protocol to replicate its KD, the group controller/key server (GCKS), by using the ZooKeeper open source coordination service.
