|Thomas PEYRIN received his engineer M.S. in 2004 from CPE Lyon and specialized in theoretical computer science at the Ecole Polytechnique in France. He completed in 2008 a doctorate in cryptography at Orange Labs, formerly known as France Telecom, during which he was awarded the Japan Society for the Promotion of Science (JSPS) grant. He previously worked as a Cryptography Expert at Ingenico (the world leader in payment solutions) and as a Research Fellow at the School of Physical and Mathematical Sciences of Nanyang Technological University in Singapore under the Singapore Lee Kuan Yew Postdoctoral Fellowship. He is now a Nanyang Assistant Professor in NTU under the Singapore NRF fellowship.|
|His favorite research topic is symmetric-key cryptography, in particular hash functions, block ciphers and cryptanalysis. He also recently got interested in lightweight cryptography, aimed for very constrained environments. Notably, he is one of the designers of LED and PHOTON, currently the smallest known block cipher and hash function. He was involved in the NIST SHA-3 competition as one of the main designers of the candidate ECHO, which has been selected for the second round of the process. He also proposed BPS, a format-preserving encryption scheme, which is currently being standardized by the American National Standards Institute.|
