One of the most difficult problems to be solved by metacomputing systems is to ensure strong authentication and authorization. The problem is complicated since the hosts involved ...
Spatial databases are entering an era of mass deployment in various real-life applications, especially mobile and location-based services. The real-time processing of spatial quer...
As network attacks have increased in number and severity over the past few years, intrusion detection system (IDS) is increasingly becoming a critical component to secure the netwo...
Abstract. We propose a conceptual model for semantic search and implement it in security access control. The model provides security access control to extend the search capabilitie...
High assurance security is di cult to achieve in distributed computer systems and databases because of their complexity, non-determinism and inherent heterogeneity. The practical ...
