Ph.D.-trained computer scientist with more than 25 years of experience in computer science and cryptography, this expert has provided technical consulting assistance in patent-related matters involving public-key cryptography, encryption algorithms, digital signatures, and secure key exchange protocols. Consulting work has included prior art investigations and infringement analysis concerning secure digital signature schemes and key exchange technologies. The expert’s technical work centers on the design and analysis of cryptographic protocols and algorithms, particularly in public-key cryptography, asymmetric encryption, chosen-ciphertext secure encryption schemes, key exchange, zero-knowledge protocols, and threshold cryptosystems. Research contributions include development and analysis of encryption schemes secure against adaptive chosen ciphertext attacks, hybrid encryption frameworks, signature schemes based on the Strong RSA assumption and bilinear maps, and foundational work in universal composability and cryptographic protocol design. The expert has authored numerous peer-reviewed publications in leading cryptography journals and conferences and has contributed extensively to computational number theory and algebra underlying modern cryptographic systems.

In addition to theoretical research, the expert has implemented high-performance cryptographic and number-theoretic software. The expert is the author and long-term maintainer of NTL, a widely used C++ library for number-theoretic computation, and a co-author of HElib, a software library implementing homomorphic encryption schemes. The expert has also served as an editor for an international standard related to asymmetric encryption, reflecting participation in the development of global cryptographic standards. Academic appointments have included Professor and Associate Professor of Computer Science, as well as research scientist positions in network security and security research groups within industry laboratories. The expert holds a Doctor of Philosophy and Master of Science in Computer Science and a Bachelor of Science in Mathematics and Computer Science.
