Event-B is a formal method for system-level modelling and analysis. Key features of Event-B
are the use of set theory as a modelling notation, the use of refinement to represent systems …

Security protocols are one of the most critical elements in enabling the secure
communication and processing of information, ensuring its confidentiality, integrity …

In B, the expression of dynamic constraints is notoriously missing. In this paper, we make
various proposals for introducing them. They all express, in different complementary ways …

We present a refinement strategy for Circus, which is the combination of Z, CSP, and the
refinement calculus in the setting of Hoare and He's unifying theories of programming. The …

B is a method for specifying, designing and coding software systems. It is based on Zermelo-
Fraenkel set theory with the axiom of choice, the concept of generalized substitution and on …

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 …

The construction of specifications is often a combination of smaller sub-components.
Composition and decomposition are techniques supporting reuse and allowing formal …

This roadmap describes ways that researchers in four areas---specification languages,
program generation, correctness by construction, and programming languages---might help …

Classical B is a state-based method developed by Abrial for specifying, designing and
coding software systems. It is based on Zermelo—Fraenkel set theory with the axiom of …

Event-B is the name of a mathematical (set-theoretic) approach used to develop complex
discrete systems, be they computerized or not. The Rodin platform is an open tool set …
