    A review on Privacy and Anonymity in electronic communications
    (Conference Procedings, 2006-10-25) Benmeziane, Souad; Badache, Nadjib
    Current Internet networking protocols provide no support to ensure the privacy of communication endpoints. An adversary can determine which addresses have asked for which services. Anonymity is now increasingly important for networked applications. This paper overviews the concept of anonymity in electronic communications, vectors for a privacy invasion, and proposed solutions. Solutions are examined from the perspective of attacks which can be reasonably expected against these systems. Particular attention is paid to mobile agents systems and how to hide the itinerary of the agent.

    Anonymous Mobile Agents
    (IEEE, 2006-04-24) Benmeziane, Souad; Larab, Baghdad
    One of the most important issues of the agent security is to keep the agent anonymity, not only in regard of the outsider (eavesdropper) but from the visited hosts too. Indeed, the observer may access agent's data, like the agent's route information data, and thus collecting sensitive information about the agent's owner. In this paper, we present a solution based on mixes to hide the itinerary of the agent. We extend the existing agent based Ajanta platform by adding this functionality. It is then possible to create protected agents capable of roaming in the Internet without revealing their whereabouts information

    An Adaptive Anonymous Authentication for Cloud Environment
    (IEEE Xplore Digital labrary, 2015-06-02) Djellalbia, Amina; Benmeziane, Souad; Badache, Nadjib; Bensimessaoud, Sihem
    Preserving identity privacy is a significant challenge for the security in cloud services. Indeed, an important barrier to the adoption of cloud services is user fear of privacy loss in the cloud. One interesting issue from a privacy perspective is to hide user’s usage behavior or meta-information which includes access patterns and frequencies when accessing services. Users may not want the cloud provider to learn which resources they access and how often they use a service by making them anonymous. In this paper, we will propose an adaptive and flexible approach to protect the identity privacy through an anonymous authentication scheme.

    A clustering technique to analyse anonymous users.
    (CPS, 2014-08-09) Benmeziane, Souad; Badache, Nadjib
    Concerns about privacy and anonymity have gained more and more attention in conjunction with the rapid growth of the Internet as a means of communication and information dissemination. A number of anonymous communication systems have been developed to protect the identity of communication participants. Nevertheless, it is important to provide ways to evaluate and measure the level of anonymity provided. We introduce in this paper the use of hierarchical clustering technique to analyse anonymous systems. We propose a new measure to evaluate anonymous systems by introducing the concept of dominant cluster. We further show that using this measure will overcome the limitations of other existing measures.
