The Cryptography Group

The Cryptography Group is led by Prof. Kaisa Nyberg. The core competence area of the group is development and application of different statistical cryptanalytic methods for symmetric-key cryptographic primitives. The main focus is on variants of differential and linear cryptanalysis, where the group has achieved significant improvements in the theory of using multiple linear approximations and applied them in practice for cryptanalysis of stream ciphers and block ciphers. The second major direction of the group's work is efficient and secure implementation of symmetric-key and asymmetric-key cryptographic primitives, such as elliptic curve based algorithms.
