  • Accelerating embedded Java for mobile devices 
    Debbabi, Mourad; Mourad, Azzam; Talhi, Chamseddine; Yahyaoui, Hamdi (2015-09-15)
    With the proliferation of wireless devices, networks, and systems, the deployment of efficient embedded Java virtual machines is becoming a challenging and important research area. Accordingly, a plethora of acceleration ...
  • Analyzing social web services' capabilities 
    Maamar, Zakaria; Yahyaoui, Hamdi; Mourad, Azzam; Sellami, Mohamed (IEEE, 2017-03-10)
    This paper looks into ways of supporting social Web services react to the behaviors that their peers expose at run time. Examples of behaviors include selfishness and unfairness. These reactions are associated with actions ...
  • From model-driven specification to design-level set-based analysis of XACML policies 
    Mourad, Azzam; Tout, Hanine; Talhi, Chamseddine; Otrok, Hadi; Yahyaoui, Hamdi (2017-02-06)
    With lot of hype surrounding policy-based computing, XACML (eXtensible Access Control Markup Language) has become the widely used de facto standard for managing access to open and distributed service-based environments ...
  • Model-Driven Specification and Design-Level Analysis of XACML Policies 
    Tout, Hanine; Mourad, Azzam; Talhi, Chamseddine; Otrok, Hadi; Yahyaoui, Hamdi (2020-09-08)
    Throughout the recent years, Web services security has been the target of many researchers. Particularly, by integrating policies and rules to govern the Web services behaviors at runtime, researchers have been able to ...
  • New approach for the dynamic enforcement of Web services security 
    Mourad, Azzam; Ayoubi, Sara; Yahyaoui, Hamdi; Otrok, Hadi (IEEE, 2017-03-08)
    We propose in this paper a new approach for the dynamic enforcement of Web services security, which is based on a synergy between Aspect-Oriented Programming (AOP) and composition of Web services. Security policies are ...
  • A novel aspect-oriented BPEL framework for the dynamic enforcement of web services security 
    Mourad, Azzam; Ayoubi, Sara; Yahyaoui, Hamdi; Otrok, Hadi (2015-11-25)
    In this paper, we propose a new framework for the dynamic enforcement of composite Web services security, which is based on a synergy between Aspect-Oriented Programming (AOP) and BPEL (Business Process Execution Language). ...
  • A selective dynamic compiler for embedded Java virtual machines targeting ARM processors 
    Mourad, Azzam; Debbabi, Mourad; Gherbi, Abdelouahed; Yahyaoui, Hamdi (2017-07-17)
    This paper presents a new selective dynamic compilation technique targeting ARM 16/32-bit embedded system processors. This compiler is built inside the J2ME/CLDC (Java 2 Micro Edition for Connected Limited Device Configuration) ...
  • Toward an abstract language on top of XACML for web services security 
    Mourad, Azzam; Otrok, Hadi; Yahyaoui, Hamdi; Baajour, Lama (IEEE, 2017-03-10)
    We introduce in this paper an abstract language on top of XACML (eXtensible Access Control Markup Language) for web services security. It is based on the automatic generation of XACML security policies from abstract XACML ...
  • Towards a BPEL model-driven approach for web services security 
    Tout, Hanine; Mourad, Azzam; Yahyaoui, Hamdi; Talhi, Chamseddine; Otrok, Hadi (IEEE, 2017-03-10)
    By handling the orchestration, composition and interaction of Web services, the Business Process Execution Language (BPEL) has gained tremendous interest. However, such process-based language does not assure a secure ...
