Algorithms and Security

Overview

The primary objective of the group is to bring together expertise in education, research and practice in the field of information security and algorithms. Our group members conduct research in areas spanning from the theoretical foundations of cryptography to the design and implementation of leading edge efficient and secure communication protocols.

The key areas of our technological expertise include Design and development of practical cryptographic mechanisms and protocols that can be employed by resource-limited devices such as sensor nodes and RFIDs.

 

  • Design of specific middleware security services that can be easily integrated in larger applications of wireless sensor networks. Implementation and deployment of realistic sensor networks with applications in environmental monitoring, health care, energy management of buildings, etc.
  • Design of protocols that focus on providing security and enhancing user privacy in ubiquitous environments that use RFID and other similar technologies. Securing transactions in peer-to-peer networks.
  • Design of security protocols and intrusion detection techniques for Ad-Hoc networks, such as authentication and key agreement protocols based on challenge-response and zero-knowledge techniques.
  • Design of security architectures for wireless and telecommunication networks (UMTS). Smart card security for e-voting and passport control.
  • Design and development low-level cryptographic primitives that can be used in securing the communications in critical applications.

Students' Views

"Innovative projects that would really sell in the actual business world, business plans with real chances to succeed and marketing plans picturing actual market situations are some of the attributes that you don’t find in an average institution that doesn’t provide up-to-date real-world education and hasn’t a drive for research and excellence. The environment in AIT is not the one you expect to find in a traditional Greek education establishment! In my opinion, it is closer to the work environment and it is designed to prepare someone for the things to come, rather than being a mere theoretic round of lectures."
