Web Service Choreography Verification Using Z Formal Specification

Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...

Verification of Interaction Overview Diagrams Using Colored Petrinets

The UML 2 Interaction Overview Diagram (IOD) provides a visual representation of system‟s overall interactions. The UML 2 IOD visualizes the behaviour of a system only for the interaction among the components and also a partial order between send and receive message events; however the semantics of communication among the interaction occurrences and process execution policy remains vague. It do...

automatic verification of authentication protocols using genetic programming

implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...

Open Interaction System Specification and Monitoring Using Semantic Web Technology

The design and development of open distributed interaction systems, where heterogeneous, autonomous, and self-interested agents can interact by entering and leaving dynamically the system, is widely recognized to be a crucial issue in the development of nowadays applications on the Internet: like e-commerce applications [1], collaborative social systems [2], or application to support the automa...

Specification and Verification using Temporal Logics

This chapter illustrates two aspects of automata theory related to lineartime temporal logic LTL used for the verification of computer systems. First, we present a translation from LTL formulae to Büchi automata. The aim is to design an elementary translation which is reasonably efficient and produces small automata so that it can be easily taught and used by hand on real examples. Our translat...
