INFORMATION SECURITY & CRYPTOGRAPHY

Information security (also cyber security) in general refers to the protection of information and information systems. Technologies providing such protection are becoming increasingly ubiquitous, that it is now used in almost all of our daily routines involving digital communications. These include credit/debit cards transactions, online shopping, pay-TV systems, key fob for cars, up to highly secure military systems.

The main underpinning mechanisms are provided by cryptography, which can generally be described as the science of securing information from unauthorized entities in such a way that only legitimate users are able to retrieve and use this information. It provides four main security services: Confidentiality, Integrity, Authentication and Non-repudiation.

The information security & cryptography group aims to investigate into cryptographic algorithms, schemes and protocols, as well as broader topics such as computer security, network security and secure information systems involving social, economy and usability aspects of security.
