The Qameleon team:

Roberto Avanzi

Roberto is a Security Architect at ARM and the company’s Resident Cryptographer. Previously, he was a Security Analyst at Qualcomm. Before that he has been a Junior Professor of Cryptology at the Ruhr-University of Bochum. Roberto holds a Ph.D. in Mathematics from the University of Essen, where his Doctorfather was Gerhard Frey. His interests are very broad and include elliptic and hyperelliptic curve cryptography, symmetric cryptography, protocols, side channel analysis and countermeasures, efficient implementation, information security, computer architectures and microarchitectures, design of secure memory subsystems. He wrote one of the very first papers showing that hyperelliptic curves over prime fields could have competitive performance to elliptic curves and the first paper on the side-channel security of hyperelliptic curves. With Preda Mihăilescu he developed the fastest and most practical variant of the AKS primality test yet. The result was independently discovered by D.J. Bernstein, and the result is credited in djb’s paper on the subject. This algorithm is often cited as the Avanzi-Mihăilescu-Bernstein algorithm. He worked in the team that designed ARM’s Pointer Authentication Code ISA extensions, and designed the block cipher QARMA used in it. But more importantly, his most valued achievement is his joint work (with Simonetta) "Leonardo", now 9 years old. Roberto is happy to acknowledge that most of the assembly work has been done by the mom.

Subhadeep Banik

Subhadeep completed his B.Tech in Electronics and Electrical Communication Engineering and M.Tech in Automation and Computer Vision from the Indian Institute of Technology at Kharagpur in 2006. He received my PhD in Computer Science from the Indian Statistical Institute, Kolkata in 2015. He was a Post Doctoral Researcher in DTU Compute at Lyngby and at Temasek Labs, NTU Singapore. Currently he is working as a Research Scientist in the LASEC group since June 2017.

Andrey Bogdanov

Andrey is the Founder and CEO of CYBERCRYPT - an expert company specializing in robust cryptographic solutions and security evaluations. Previously, he was Associate Professor in Cryptology at Technical University of Denmark. Before that, he was employed with Microsoft in the USA, Siemens in Germany, and KU Leuven in Belgium. Andrey holds a PhD in cryptology from Ruhr University Bochum in Germany. His research interests include symmetric cryptology, lightweight cryptography, whitebox cryptography, side-channel analysis, as well as efficient and secure implementations. Andrey has co-designed such primitives as block cipher PRESENT (ISO/IEC standard), hash function SPONGENT (ISO/IEC standard), and authenticated cipher COLM (CAESAR final portfolio).

Orr Dunkelman

Orr is an associate professor in the Computer Science department at the University of Haifa. His research focuses on cryptanalysis, cryptography, security, and privacy, especially in the context of biometric data. Orr's work in symmetric-key cryptanalysis includes analyzing many ciphers and the introduction of several new cryptanalytic techniques. Orr has worked on many of the most widely deployed ciphers such as the AES, KASUMI (used in 3G mobile networks), A5/1 (used in GSM networks), and IDEA. He has published over 80 publications in international venues, including the best paper awards from FSE 2012 and CRYTPO 2012. He has also served on more than 80 program committees, five times as a program chair, is the general chair of EUROCRYPT 2018, and has served on several boards and steering committees (e.g., the IACR board). Orr has obtained his Ph.D. in computer science in 2006 from the Technion and a B.A. in computer science in 2000 from the Technion.

Senyang Huang

Senyang is a post doctoral researcher at the University of Haifa. He has obtained his Ph.D. in mathematics in 2018 from Tsinghua University, Beijing, under the supervision of Prof. Xiaoyun Wang. His research interests include design and analysis of symmetric-key cryptographic primitives, lightweight cryptography, etc.

Francesco Regazzoni

Francesco is senior researcher at the Università della Svizzera italiana (Lugano, Switzerland). He received his Master of Science degree from Politecnico di Milano and his PhD degree at the ALaRI Institute of University of Lugano. He has been assistant researcher at the Université Catholique de Louvain and at Technical University of Delft, and visiting researcher at several institutions, including NEC Labs America, Ruhr University of Bochum, EPFL, and NTU Singapore. His research interests are mainly focused on embedded systems security, covering in particular side channel attacks, electronic design automation for security, hardware Trojans, and low energy cryptography. He has published more than 100 peer reviewed journal and conference papers in the area of security and design automation, and has been in the technical program committed of top conferences of the area.
