Regarding the important place occupied by the new information technologies in modern societies, information security is nowadays present in the areas of systems, contents and services in order to prevent, identify and reduce malicious attacks. The information security task is to ensure the integrity, the confidentiality, the availability and the traceability of data and their process. Security is an essential element in all Computer systems.

The Division of computer security is mainly aiming to acquire expertise and to suggest solutions to ensure a smooth operating of computer systems and to protect those systems from intruders.

The division seeks to participate in the development of the national network of scientific and technical information by leading research and development projects, and training.

The computer security division teams works include all of the following areas: systems,networks, data and applications.

Research areas:

• Network Security
• Cyber physical systems Security
• Data security and privacy

The Scientific and Technical Information (STI) is the basic building block of society knowledge and thus, it becomes a digital content that must be made intelligible to everyone according to their specific needs while controlling the legal and the socio-economic environment related to digital technology.

With its multidisciplinary components and researchers specialized in computer science, mathematics and humanities, the Division of Research and Development in Information Science is striving to offer large corpus analysis tools including Arabic language, using techniques of Automatic Language Processing and Artificial Intelligence. The division also proposes mathematic models for the evaluation of information and modeling digital uses, along with a national approach of STI strategic intelligence, conducting reflections on open access, new business models and the legal framework of STI and ICT.

Research areas

• Natural Languages Processing.
• Knowledge representation, standards and metadata.
• Digital Humanities.
• Mathematics of Information.
• Semantic Web.
• Open access and new modes of information production.
• ICT law and socio-economics.

The activities of the Division of Networks and Distributed Systems target to study, master and introduce technologies associated with e-infrastructures.

These e-infrastructures induce mastering of communication technologies and developing new application architectures such as CLOUD and GRID technologies wich aim to share resources in terms of computing power and storage.

These activities aim to establish e-infrastructures such as the Algerian Research Network (ARN) and the National Computing Grid “ DZ e-Science GRID” and to consolidate the skills and technological know-how.

Research areas 

• Collaborative and Integrated Systems;
• Network infrastructure and grid computing technologies;
• Web Services and Content Management Technologies;
• Distributed applications on computing grids and cloud applications;
• Security of communication networks and network services
