Heimdahl and N.G. Leveson, 1995; 1996). We implemented the analysis procedures in a prototype tool and evaluated their effectiveness and efficiency on a large real world requirements specification expressed in an hierarchical state based language called RSML (Requirements State Machine Language). Although our approach has been largely successful, there are some drawbacks with the current implementation that must be addressed. Our prototype implementation uses Binary Decision Diagrams (BDDs) to perform the analysis. Unfortunately, since BDDs treat predicates and functions as uninterpreted and thus fail to capture their semantics, the use of BDDs can lead to large numbers of spurious (false) error reports. We are currently investigating how the Prototype Verification System (PVS) and its theorem proving component can help us increase the accuracy of our analysis. PVS is a verification system that provides an interactive environment for writing formal specifications and checking formal proofs. The paper discusses the problems with spurious error reports and describes our experiences using the Prototype Verification System to increase the accuracy of our analysis results.","PeriodicalId":129829,"journal":{"name":"Proceedings.

Since design of diverse programs may use hardware parts in the same way, the hardware fault coverage obtained is insufficient. To improve hardware fault coverage, a method is presented that systematically transforms every instruction of a given program into a modified instruction (sequence), keeping the algorithm fixed. This transformation is based on a diverse data representation and accompanying modified instruction sequences, that calculate the original results in the diverse data representation. If original and systematically modified variants of a program are executed sequentially, the results can be compared online to detect hardware faults. For this method, different diverse data representation have been examined. For the most suitable representation, the accompanying modified instruction sequences have been generated at assembler level and at high language level. The theoretically estimated improvement of the fault coverage of design diversity by additionally using systematically generated diversity have been confirmed by practical examinations.","PeriodicalId":129829,"journal":{"name":"Proceedings.

We propose an architectural framework that speeds up the process of introducing new technologies to MLS users. We examine the drawbacks of traditional MLS approaches and take a fresh look at the requirements of MLS users. We then introduce security critical components that can enable MLS solutions and an MLS architectural framework that can accommodate not only legacy systems but also new technologies including DOC, without jeopardizing system security. Our framework separates security critical components/functions from the rest of the system because these components must go through rigorous evaluation/certification processes. This approach enables the secure use of new technologies for MLS users.","PeriodicalId":129829,"journal":{"name":"Proceedings. IEEE High-Assurance Systems Engineering Workshop (Cat.
