WE ARE RECRUITING: Postdoc/PhD candidates interested to work on cryptography/automated solvers/machine learning, contact Prof. Peyrin for more info on available positions

Welcome to the SYmmetric cryptography and machine Learning Lab (SyLLab) page.

We are part of the School of Physical and Mathematical Sciences / School of Computer Science and Engineering of Nanyang Technological University, Singapore. The lab is led by Prof. Thomas Peyrin and its research scope is cryptography in general, with a special focus on the analysis, design and implementation of symmetric-key primitives (hash functions, block and stream ciphers, MACs, etc), lightweight cryptography; as well as machine learning in general, with a special focus on possible links between machine learning and security.
