We apply static analysis and symbolic interpretation techniques to reverse engineer the semantics of legacy assembler code. We examine the case of IBM-1800 programs in detail. Fro...
A symbolic semantics for Full LOTOS in terms of symbolic transition systems is de ned, following the approach taken for message passing CCS in HL95a], altered to take account of th...
Abstract. We propose a framework for reasoning about program security building on language-theoretic and coalgebraic concepts. The behaviour of a system is viewed as a mapping from...
Bialgebraic semantics, invented a decade ago by Turi and Plotkin, is an approach to formal reasoning about well-behaved structural operational specifications. An extension of alg...
A previously introduced combination of the bialgebraic approach to structural operational semantics with aic modal logic is re-examined and improved in some aspects. Firstly, a mo...
