NTT Research CIS Lab to Showcase Research Breakthroughs at Crypto 2021NTT Research, Inc., a division of NTT (TYO:9432), today announced that members of its Cryptography & Information Security (CIS) Lab authored or co-authored 18 papers that are being delivered at Crypto 2021, one of the leading international conferences on cryptologic research. Organized by the International Association for Cryptologic Research (IACR), this year's event will take place virtually August 16-20 and feature 2 invited talks, 26 sessions and more than 100 papers. The proceedings of Crypto 2021, the 41st Annual International Cryptology Conference, will be published by Springer in its Lecture Notes in Computer Science (LNCS) series. NTT (News - Alert) Research is one of two gold-level sponsors of this year's event. The IACR this year called for papers on "any cryptographic topic, including but not limited to foundational theory and mathematics; the design, proposal and analysis of cryptographic primitives and protocols; secure implementation and optimization in hardware or software; and applied aspects of cryptography." A program committee consisting of more than 50 academics evaluated the submissions and grouped the accepted papers into 15 general topics. The accepted papers associated with CIS Lab scientists fell into the following categories: signatures, multi-party computation (MPC), quantum cryptography, codes and extractors, secret sharing, zero-knowledge proofs, encryption++, lattice cryptanalysis, foundations and protocols. The largest number of papers at this year's event address MPC, which provides ways of performing computing on encrypted data. "We are very pleased to support this scientific organization and trust that Crypto 2021 will be a fruitful exchange of new insights into current and enduring cryptologic challenges," said Kazuhiro Gomi (News - Alert), NTT Research President and CEO. "Very best wishes to all presenters at this year's event." Directed by NTT Fellow, Tatsuaki Okamoto, the CIS Lab has assembled a team of world-class cryptographers over the past two years. The papers authored and co-authored by CIS Lab computer scientists (names noted with an asterisk and links to any related CIS Lab blog posts or press releases), along with their category and time slot Eastern U.S.) on the Crypto 2021 schedule, include the following:
"On the Round Complexity of Secure Quantum Computation"
"One-Way Functions Imply Secure Computation in a Quantum World"
"Compact Ring Signatures from Learning With Errors"
"Counterexamples to New Circular Security Assumptions Underlying iO"
"Unconditional Communication-Efficient MPC via Hall's Marriage Theorem"
"ATLAS: Efficient and Scalable MPC in the Honest Majority Setting"
"New Approaches for Quantum Copy-Protection"
"Hidden Cosets and Applications to Unclonable Cryptography"
"Non-Malleable Codes for Bounded Parallel-Time Tampering"
"Traceable Secret Sharing and Applications"
"Time- and Space-Efficient Arguments from Groups of Unknown Order"
"Limits on the Adaptive Security of Yao's Garbling"
"Broadcast Encryption with Size N^{1/3} and More from k-Lin"
"White Box (News - Alert) Traitor Tracing"
"Does Fiat-Shamir Require a Cryptographic Hash Function?"
"Targeted Lossy Functions and Applications"
"A Logarithmic Lower Bound for Oblivious RAM (News - Alert) (for all parameters)"
"Oblivious RAM with Worst-Case Logarithmic Overhead"
The invited talks this year include one by Vanessa Teague on "Which e-voting problems do we need to solve?" and another by Jens Groth on "A World of SNARKS." (A SNARK is a succinct, non-interactive argument of knowledge.) A session on the Award Papers will take place on Tuesday, Aug 17. Last year's event featured two NTT-related Best Paper awards. Six affiliated pre-conference events held August 14-15 focus on the topics of Failed Approaches and Insightful Losses, Mentoring, Reduction Proofs in Pseudocode, Mathematical Cryptography, Privacy-Preserving Machine Learning, and Attacks in Cryptography. In addition to the two gold-level sponsors, Crypto 2021 is supported by another sponsor at the silver level and six at the bronze level. About NTT Research NTT Research opened its offices in July 2019 as a new Silicon Valley startup to conduct basic research and advance technologies that promote positive change for humankind. Currently, three labs are housed at NTT Research facilities in Sunnyvale: the Physics and Informatics (News - Alert) (PHI) Lab, the Cryptography and Information Security (CIS) Lab, and the Medical and Health Informatics (MEI) Lab. The organization aims to upgrade reality in three areas: 1) quantum information, neuroscience and photonics; 2) cryptographic and information security; and 3) medical and health informatics. NTT Research is part of NTT, a global technology and business solutions provider with an annual R&D budget of $3.6 billion.
