As software systems become more complex the overall system structure { or software architecture { becomes a central design problem. An important step towards an engineering discip...
The B method is one of the most used formal methods, when reactive systems is under question, due to good support for refinement. However, obtaining the formal model from requireme...
Prior research into search system scalability has primarily addressed query processing efficiency [1, 2, 3] or indexing efficiency [3], or has presented some arbitrary system arch...
Abstract. We study two closely related primitives: Broadcast Encryption and Key Predistribution Schemes (KPS). Broadcast Encryption allows a broadcaster to broadcast an encrypted m...
Abstract. This paper describes recent work concerned with the speci cation of requirements on interactive systems and the de nition of user-level properties of such systems. A form...
