Information Security Group


The Telematic Services research group focuses its activity on the development and proposal of telematic services in telecommunication networks, stressing the security services.  Audiovisual services, distributed media systems and corporative services within intranet environments and Internet are the the group’s main research topics.

Regarding security services, the main areas of interest are authentication, privacy, copyright protection in multimedia content, wireless communication security and group communication security.

Moreover, the group deals with QoS management for hybrid networks, modeling and evaluation of the performance of multimedia services and the design of self-configuring network architectures for providing efficient multimedia content.

The group is involved in several national and international projects, and its research has been extensively published in numerous magazines and international congresses.

The main topics in which the research group ISG/SISCOM is currently interested include:

  • Information security in telecommunication networks

  • P2P applications and services

  • QoS in distributed multimedia services

  • Audiovisual services
  • Multimedia service modeling

  • QoS and cross-layer in network architecture design
