• World-leaders in Cryptography: Amit Sahai

  Amit is a professor of computer science at UCLA and is the director of the Center for Encrypted Functionalities. Amit has been cited in his research work over 63,000 times and has an h-index of 91.  In 2000, he graduated with a PhD from MIT and then moved to Princeton. In 2004, he then moved to UCLA. Over the years, he has made so many great advancements,  including being the co-inventor of many areas of cryptography, including indistinguishability obfuscation schemes, functional encryption, attribute-based encryption, Zero-Knowledge Proofs and Multiparty Computation. In 2018, he was elected as an ACM Fellow for his work for the "contributions to cryptography and to the development of indistinguishability obfuscation", and elected as a Fellow of the International Association for Cryptologic Research for "fundamental contributions, including to secure computation, zero knowledge, and functional encryption, and for service to the IACR". In 2023, Amit received the Test of Time Award from the International Association for Cryptologic Research for his 2008 paper "Efficient Non-interactive Proof Systems for Bilinear Groups". Then, in 2022, he received the Michael and Sheila Held Prize from the National Academy of Sciences and which credits outstanding, innovative, creative, and influential research in the areas of combinatorial and discrete optimisation. And, in teaching, in 2016, he won the UCLA Samueli’s Lockheed Martin Excellence in Teaching Award.

• World-leaders in Cryptography: Bart Preneel

  Bart is a Professor in the Electrical Engineering department at KU Leuven in Belgium. He co-invented the Miyaguchi (Meya-Goochy)–Preneel scheme and which converts a block cipher into a hash function. Bart is also one of the co-inventors of the RIPEMD-160 hashing method, and which is used in Bitcoin addresses. He also co-designed the stream ciphers MUGI and Trivium, the MAC Algorithms Chaskey and MDxMAC and the authenticated encryption algorithm AEGIS that is used to encryption of data at rest ion Google cloud. Bart was the President of the International Association for Cryptologic Research (IACR) from 2008 to 2013 and one of his hobbies is conducting the University of Leuven Bigband and playing saxophone in a Dixieland band.Bart consults for industry and government on cybersecurity and privacy.   He founded the mobile authentication startup nextAuth and holds roles in Approach Belgium, Tioga Capital Partners, and Nym Technologies. During the pandemic he co-designed the DP-3T scheme for privacy-friendly contact tracing and managed the Belgian Coronalert app.  Actively engaged in cybersecurity policy, he contributes to ENISA as an Advisory Group member for the EU.

• World-leaders in Cryptography: Ivan Damgard

  Ivan Damgard is a professor in the Department of Computer Science at Aarhus University in Denmark.  He is the co-inventor of the Merkle-Damgard construction, and which was used in MD5, SHA-1 and SHA-2. In 2020, he received the Test of Time Award for a paper entitled "A Generalisation, a Simplification and Some Applications of Paillier's Probabilistic Public-Key System", and in 2021 he received an ACM award for the Test of Time for a paper entitled "Multiparty unconditionally secure protocols. In 2010, he was elected as a Fellow of the International Association for Cryptologic Research.  Ivan has also co-founded two cryptography companies: Cryptomathic and Partisia. Web: here.

• World-leaders in Cryptography: Chris Peikert

  Chris is a Professor in the Computer Science and Engineering department at the University of Michigan. He completed his PhD in 2006 at the MIT Computer Science and AI Laboratory under the mentorship of Silvio Micali.  He received a Test of Time award at Crypto 2008 for a paper entitled "A Framework for Efficient and Composable Oblivious Transfer" and also a TCC Test of Time award for his paper on “Efficient Collision-Resistant Hashing from Worst-Case Assumptions on Cyclic Lattices,” in 2006.  In 2024, Chris was elected as a Fellow of the International Association for Cryptologic Research and is seen as one of the world leaders in lattice-based methods.

• World-leaders in Cryptography: Clifford Cocks

   Clifford Cocks  is a British mathematician and cryptographer. While working at GCHQ, he invented public key encryption, and which predates the work of the RSA and Diffie-Hellman methods. He studied mathematics as an undergraduate at Kings College, Cambridge, and then joined the Communications-Electronics Security Group (CESG) at GCHQ in 1973. After his discovery of a usable public key encryption method, he went on to create one of the first Identity-Based Encryption methods and which is based on quadratic residues rather than bilinear pairings. In 2008, he was made a Companion of the Order of the Bath (CB).  Then, in 2010, he and James Ellis and Malcolm Williamson were honoured by the IEEE for their part in the development of public key encryption. In 2015, he was elected as a Fellow of the Royal Society, and, in the same year, he received an honorary PhD from the University of Birmingham. Then, in 2021, Clifford was inducted into the Cryptologic Hall of Honour.   Read more: https://medium.com/asecuritysite-when-bob-met-alice/so-who-invented-public-key-encryption-213ceef7759
