....technical advantages, the correctness of the security mechanisms become a major concern. The purpose of this paper is to give an overview over an ongoing case study [3] that provides a formal model of the open CVS server architecture and (the begin of) a formal analysis performed with HOL Z 2. 0 [2]. We believe that this application is quite typical for client server applications, where a particular security model must be mapped on the concrete security technology of POSIX UNIX. We will proceed as follows: After a discussion on the architecture notion and its refinement, we will first ....

.... languages, the situation is not so clear cut: while direct implementations in a programming environment are predominant [11, 12, 13] which result in special logic, special purpose theorem provers sometimes based on ad hoc deduction technology, only a few tools are based on embeddings [14, 15, 16]. There are two main advantages of the embedding approach: Beside the reuse of existing theorem prover engines, building such tools based on a conservative embedding into a logical framework also guarantees the safety and relative logical consistency of the tool. Unfortunately, in order to be ....
....program succeeds in our application in all cases in our non trivial application language. Although a more precise characterization of success is impossible here due to the generality of the framework, we believe that the approach will be applicable for language embeddings for SML, Haskell or Z [16] with similar success since the underlying semantic combinators are the same; also our implementation of LIFT E will be reusable; the same holds for many basic generic theorems over semantical combinators from the embedding adaption layer, the functional adaption layer and to a lesser extent ....
