At Simula UiB we study the details of how cryptographic algorithms work. We estimate how much resources the best attacks need in order to break the security of particular ciphers. This research gives assurance that the cryptography we all rely on really is secure, even when we consider new attack methods and the increase in computing power.
New types of cryptographic algorithms, like fully homomorphic encryption, has the potential to solve many of the trust and privacy issues in cloud computing today. The challenge these novel algorithms curently face is in terms of efficiency. Simuila UiB does research in this area also, trying to make new cryptographic techniques more practical and useful in the real world.
