The research expertise at UCL, strong of over 30 researchers, covers the various layers of cryptography and its application to information security, namely:

  • Design and analysis of strong security protocols: authentication, multiparty computation, voting, provable security, evaluations, ...;
  • Design and analysis of efficient and secure cryptographic primitives symmetric and asymmetric encryption, digital signatures, ... ;
  • Efficient implementations of cryptographic primitives under various environmental constraints, both in software and hardware smart card, RFID, FPGA, ASIC, sensor networks, ...;
  • Implementation-related attacks (fault injection, side-channel) and countermeasures (distance-bounding protocols, masking, ...);
  • Practical attacks against security applications: time-memory tradeoff, biometric passport, ...;
  • Security from the physical layer: information theoretic cryptography, cooperative communications, ...;
  • Algebra: number theory, algebraic geometry, quadratic forms, algebras over arbitrary fields, ...;
  • Privacy-related issues at all levels ;
  • Computer security: viruses, spam, distributed attacks, wireless networks, ...
