Network maintenance

Quality of functionality is the most important set of measurements to be considered for evaluation, because it includes the most desirable qualities a user expects from a federated trust management system. Three basic qualities of functionality required for federated trust management are discussed below.

All network maintenance management systems try to build trust relationships, construct trust models, exchange trust related information, and enforce trust behavior with minimal computational cost and time [16]. Computational efficiency can be gauged by the time needed to complete a specific task, so the time needed for a specific federation task is a useful metric.
