Cyber security examines the methods, techniques and tools for securing computer systems that are accessible through a network, typically the Internet, which is often known as cyberspace.
Most networked computing systems can be considered socio-technical systems and the successful defence against cyber-attacks requires consideration of a broad range of human and technical factors, from the general security awareness among agents in an organisation to the proper enforcement of security policies through cryptography and access control mechanisms.
Cryptology or cryptography is about secrecy and authentication. There is an increasing need for ensuring secrecy and authentication in communications today. Numerous daily live actions have to be secured using modern cryptography, such as when you surf on the Internet, when you talk on your mobile phone and when you open your car.
Cyber Security section is a world leading research group in the field of symmetric cryptography, and we concentrate our research efforts on the disciplines: Symmetric encryption, Cryptographic hashing, Message authentication, Boolean functions.
