Contents

Chris Peikert is a researcher and entrepreneur noted for foundational work in lattice-based cryptography, the learning with errors problem, and contributions to post-quantum cryptographic standards. He has held academic positions at Duke University and University of California, San Diego, worked in industrial research at Microsoft Research and IBM, and co-founded companies in the cryptographic and blockchain sectors. His research intersects with efforts by organizations such as the National Institute of Standards and Technology, the Internet Engineering Task Force, and consortia including the Cloud Security Alliance and the Cryptography Research Group.

Early life and education

Peikert completed undergraduate studies at University of California, Davis and earned a Ph.D. at University of Wisconsin–Madison under advisors connected to the Institute for Mathematics and its Applications, with doctoral work that engaged topics related to Ajtai–Dwork, Regev, and lattice problems prominent in the research communities around MIT, Harvard University, Princeton University, Stanford University, and University of California, Berkeley. During his graduate training he collaborated with scholars affiliated with institutions like IBM Research, Microsoft Research, Bell Labs, AT&T Labs, and research groups tied to the Simons Foundation and the National Science Foundation. His formative education overlapped with contemporaneous developments at centers such as the International Association for Cryptologic Research, the Cryptology ePrint Archive, and workshops hosted by IEEE and ACM.

Peikert's work advanced lattice cryptography by formalizing reductions and constructing primitives based on worst-case hardness of lattice problems, connecting to the Shortest Vector Problem, the Learning with Errors problem introduced by Oded Regev, and reductions related to the GapSVP problem studied at universities like Columbia University and Cornell University. He published influential results on trapdoor functions and homomorphic constructions that influenced projects at MIT Lincoln Laboratory, SRI International, Los Alamos National Laboratory, and collaborations with researchers at École Normale Supérieure, École Polytechnique, and ENS Lyon. His theoretical contributions informed standardization efforts led by NIST and academic workshops at CRYPTO, EUROCRYPT, ASIACRYPT, TCC, and symposiums organized by the Royal Society and IMS. Peikert also explored lattice-based digital signatures, identity-based encryption, and key-exchange mechanisms relevant to protocols designed by teams at IETF and implementers at OpenSSL, Mozilla, and Google.

In industry, Peikert held research positions at IBM and Microsoft Research, where he engaged with applied teams working on post-quantum readiness alongside engineers from Google, Amazon Web Services, Cloudflare, Cisco, and Qualcomm. He co-founded and advised startups in the blockchain and secure computation sectors that interacted with consortia such as Hyperledger, Ethereum Foundation, Algorand Foundation, and Dfinity Foundation. His entrepreneurial work connected to firms in secure multiparty computation and homomorphic encryption that collaborated with Duality Technologies, Zama, Enveil, and Certara. He has served on advisory boards and contributed to initiatives involving DARPA, NSA, European Commission, European Telecommunications Standards Institute, and industrial research labs including Fujitsu Laboratories and Hitachi Research.

Peikert's research has been recognized by peers across academic and industrial venues including best-paper distinctions at conferences such as CRYPTO, EUROCRYPT, and TCC, invitations to speak at forums hosted by the Simons Institute, the Mathematical Sciences Research Institute, and panels organized by NIST and the IETF. His work has been cited in technical reports by NSA, policy analyses by the National Academies of Sciences, Engineering, and Medicine, and surveys from the IEEE Information Theory Society and the ACM Special Interest Group on Security, Audit and Control. He has been listed among leading contributors in reviews by the Cryptology ePrint Archive and referenced in textbooks from publishers like Springer, Cambridge University Press, and Oxford University Press.

Representative publications include peer-reviewed articles appearing in proceedings of CRYPTO, EUROCRYPT, TCC, and journals such as the Journal of Cryptology, SIAM Journal on Computing, and IEEE Transactions on Information Theory. His papers have worked alongside contributions from researchers at MIT, Harvard University, Princeton University, Stanford University, University of Toronto, McGill University, ETH Zurich, EPFL, Max Planck Institute for Informatics, and Weizmann Institute of Science. He is listed as inventor or co-inventor on patents filed with offices including the United States Patent and Trademark Office and patent authorities in the European Patent Office, covering trapdoor functions, lattice-based key-exchange mechanisms, and cryptographic primitives applicable to blockchain and secure multiparty computation. Selected works have been incorporated into standards discussions at NIST and implementation references at projects such as OpenSSL, libsodium, and prototype stacks developed by teams at Cloudflare, Google Chrome, and Mozilla Firefox.
