IDictionary Options - Performance Test - SortedList vs. SortedDictionary vs. Dictionary vs. HashtablePlease note that the advantage of Hashtable over generic Dictionary for insert and search operations demonstrated here is actually because the tests are based on NON generic IDictionary interface, so each insert or search action is accompanied with check for the key type.
This paper analyzes the requirement of authorization service for grid computing systems and proposes the use of threshold closure as a basic mechanism for implementing authorization service in grid computing systems. While pointing out the desirable features of threshold closure for complex authorization policies, the paper also discusses the practical limitations of threshold closure in such an environment, and then puts forward a new authorization service for virtual organization. In addition, an access control protocol which is based on PKI is designed in the paper.
