We propose an epistemic logic for the applied pi calculus, which is a variant of the pi calculus with extensions for modeling cryptographic protocols. In such a calculus, the security guarantees are usually stated as equivalences. While process calculi provide a natural means to describe the protocols themselves, epistemic logics are often better suited for expressing certain security propertie...
The pi calculus has been applied to modelling biochemical networks. In these applications, the modelling is done without considerations to exceptions. The Ipi calculus, the Interference pi calculus, is introduced to describe the signal transduction with aberrance. The calculus is obtained by adding two aberrant actions into the pi calculus and a tag system to check existing aberrance. A model o...
In this paper we report on some recent work to formally specify and verify electronic voting protocols. In particular, we use the formalism of the applied pi calculus: the applied pi calculus is a formal language similar to the pi calculus but with useful extensions for modelling cryptographic protocols. We model several important properties, namely fairness, eligibility, privacy, receipt-freen...
We present a symbolic transition system and bisimulation equivalence for psi-calculi, and show that it is fully abstract with respect to bisimulation congruence in the non-symbolic semantics. A psi-calculus is an extension of the pi-calculus with nominal data types for data structures and for logical assertions representing facts about data. These can be transmitted between processes and their ...
We present in this technical report a non-uniform static analysis for detecting the term-substitution property in systems specified in the language of the applied pi calculus. The analysis implements a denotational framework that has previously introduced analyses for the pi calculus and the spi calculus. The main novelty of this analysis is its ability to deal with systems specified in languag...
We present the analysis of a protocol for private authentication in the applied pi calculus. We treat authenticity and secrecy properties of the protocol. Although such properties are fairly standard, their formulation in the applied pi calculus makes an original use of process equivalences. In addition, we treat identity-protection properties, which are a delicate concern in several recent pro...
Applied process calculi include advanced programming constructs such as type systems, communication with pattern matching, encryption primitives, concurrent constraints, nondeterminism, process creation, and dynamic connection topologies. Several such formalisms, e.g. the applied pi calculus, are extensions of the the pi-calculus; a growing number is geared towards particular applications or co...
We propose a symbolic semantics for the finite applied pi calculus, which is a variant of the pi calculus with extensions for modelling cryptgraphic protocols. By treating inputs symbolically, our semantics avoids potentially infinite branching of execution trees due to inputs from the environment. Correctness is maintained by associating with each process a set of constraints on symbolic terms...
