Abstract

The concept of algebraic state machine has been introduced in [3] as a state transition system the states of which are each defined as an algebra, and that communicate through channels.

To make efficient use of this concept, one needs a formal semantics, as well as notions of composition and refinement, which are provided in the present work. To demonstrate their usefulness for an application area of major interest, we show how to extend algebraic state machines with data types modelling cryptographic operations and with an adversary model to reason about security-critical systems. As an example we consider a cryptographic protocol proposed in the literature.
