Verifying Cross-layer Interactions through Formal Model-based Assertion Generation

Asieh Salehi Fathabadi, Mohammadsadegh Dalvandi, Michael Butler, Bashir M. Al-Hashimi
2019 IEEE Embedded Systems Letters  
Our approach involves a formal model of the APIs, developed using the Event-B formal method which is automatically translated to a set of assertions and embedded in the existing implementation of APIs.  ...  In this paper, we propose a formal approach to integration testing through automatic generation of runtime assertions in order to test the implementation of the APIs.  ...  Our integration testing approach consists of three stages: 1) formal modelling of the framework APIs in Event-B language, 2) formal verification of consistency properties (including order of API calls  ...

Towards Runtime Verification via Event Stream Processing in Cloud Computing Infrastructures [article]

Domenico Cotroneo, Luigi De Simone, Pietro Liguori, Roberto Natella, Angela Scibelli
2020 arXiv   pre-print
To face these issues, we propose a lightweight approach to runtime verification, for monitoring and failure detection of cloud computing systems.  ...  We performed a preliminary evaluation of the proposed approach in the OpenStack cloud management platform, an "off-the-shelf" distributed system, showing that the approach can be applied with high failure  ...  A={all distinct events of type "A" happened in [t, t+∆]} B ={all distinct events of type "B" happened in [t, t+∆]} (2) with |A|=|B|=n.  ...

Towards a Process Calculus for Rest: Current State of the Art

Dariusz Dwornikowski, Andrzej Stroiński, Jerzy Brzeziński
2015 Foundations of Computing and Decision Sciences  
In order to address problems of modeling and verification of Web services, several process calculi have been proposed for SOAP-based Web services but none for the RESTful Web services based systems.  ...  The aim of the article is to see how process calculi for SOAP-based systems deal with different aspects of their modeling domain, and whether their approaches can be used to model RESTful and ROA systems  ...  The aim for the Authors was to formalize REST and ROA behavior in order to provide an automated verification of a behavior of a RESTful service.  ...

Formal verification of the YubiKey and YubiHSM APIs in Maude-NPA [article]

Antonio González-Burgueño, Damián Aparicio, Santiago Escobar, Catherine Meadows, José Meseguer
2018 arXiv   pre-print
This is not surprising, because both YubiKey and YubiHSM, which make use of cryptographic APIs, involve a number of complex features: (i) discrete time in the form of Lamport clocks, (ii) a mutable memory  ...  for storing previously seen keys or nonces, (iii) event-based properties that require an analysis of sequences of actions, and (iv) reasoning modulo exclusive-or.  ...  Figure 1 [18] is a simple example of a YubiKey API execution, where the three roles are as follows: the user (Browser), the service (YubiCloud), and the verification server running the YubiKey API.  ...

From Requirements Engineering to Safety Assurance: Refinement Approach [chapter]

Linas Laibinis, Elena Troubitsyna, Yuliya Prokhorova, Alexei Iliasov, Alexander Romanovsky
2015 Lecture Notes in Computer Science  
Formal modelling and verification are widely used in the development of safety-critical systems. They aim at providing a mathematically-grounded argument about system safety.  ...  Our approach establishes a link between safety requirements, Event-B models and corresponding fragments of a safety case.  ...  In terms of Event-B, the particular system states we are interested in are usually associated with some desired post-states of specific model events.  ...

The main goal of the tool is to provide an easy-to-use environment for the verification of requirements in Cyber-Physical Systems (CPS).  ...  On the other hand, automated consistency checking most often requires overburdening formalizations. In this paper we introduce REQV, a tool for formal consistency checking of requirements.  ...  server application that provides services as REST APIs.  ...
