Abstract.This paper describes the tool csp2B which provides a means of combining CSP-like descriptions with standard B specifications. The notation of CSP provides a convenient way of describing the order in which the operations of a B machine may occur. The function of the tool is to convert CSP-like specifications into standard machine-readable B specifications which means that they may be animated and appropriate proof obligations may be generated. Use of csp2B means that abstract specifications and refinements may be specified purely using CSP or using a combination of CSP and B. The translation is justified in terms of an operational semantics.

We propose in this paper a formal framework based on the B method, that supports the development of secured smart card applications. Accordingly to the Common Criteria methodology, we focus on the formal definition and modelling of access control policies by means of dedicated B models expressing, on one hand, the access control rules, and, on the other hand, the dynamics of the system. These models are then weaved to produce a security kernel. From there, we propose a conformance relationship that aims at establishing whether a concrete representation of the system complies, at the security level, with the security kernel. This embraces both a well-defined notion of security conformance as well as traceability allowing to relate basic events appearing at the level of applications with abstract security policies. This approach is put in practice on an industrial case study in the context of the POSÉ project, involving both academic and industrial partners.

Testing refinements of state-based formal specifications

A specification provides a concise description of a system, and can be used as both the benchmark against which any implementation is tested, and also as a means to generate tests. Formal specifications have potential advantages over informal descriptions because they offer the possibility of reducing the costs of testing by automating part of the testing process. This observation has led to considerable interest in developing test generation techniques from formal specifications, and a number of different methods have been derived for state‐based formalisms such as Z, B and VDM. However, after tests have been derived from a formal specification, the specification might be refined further before it is implemented, and therefore a mechanism is needed to relate the abstract tests to the refined implementation. The purpose of this paper is to provide such a method by exploring the relationship between testing and refinement. In this paper a model for test generation is used which constructs a finite state machine (FSM) from a Z specification by using a Disjunctive Normal Form (DNF) partition analysis of the state and operations. The finite state machine is then used to derive suitable test suites. The paper decribes a way of calculating an FSM for a refinement from an abstract FSM together with the information about the refinement embodied in the retrieve relation. This means that it is possible to test an implementation by generating a new concrete finite state machine from a set of abstract tests. Copyright © 1999 John Wiley & Sons, Ltd.
