Cryptography is a fundamental component for modern communication technologies and form the technical basis for trustworthy communication in the information age.

Internet banking, secure payment systems, digital signatures – all would be unthinkable without the use of modern encryption technologies. Designing next generation secure and intelligent communication systems raises many new challenges which also call for new approaches in cryptography. Therefore AIT offers new cryptographic methods and investigates how these can be used to make tomorrow's ICT systems safer. Methods, concepts and prototypes are developed to help protect user data and enhance privacy in the interaction with ICT in the context of cloud computing and the Internet of Things (IoT).
