Multi-Party Threshold Cryptography MPTC

The multiparty paradigm of threshold cryptography enables a secure distribution of trust in the operation of cryptographic primitives. This can apply, for example, to the operations of key generation, signing, encryption and decryption. This project focuses on threshold schemes for cryptographic primitives: using a “secret sharing” mechanism, the secret key is split across multiple "parties", such that, even if some (up to a threshold f out of n) of these parties are corrupted, the key secrecy...

Post-Quantum Cryptography PQC

The Candidates to be Standardized and Round 4 Submissions were announced July 5, 2022. NISTIR 8413, Status Report on the Third Round of the NIST Post-Quantum Cryptography Standardization Process is now available. NIST has developed Guidelines for Submitting Tweaks for Fourth Round Candidates. NIST has initiated a process to solicit, evaluate, and standardize one or more quantum-resistant public-key cryptographic algorithms. Full details can be found in the Post-Quantum Cryptography...

Stateful Hash-Based Signatures HBS

In Special Publication 800-208, Recommendation for Stateful Hash-Based Signature Schemes NIST approves two schemes for stateful hash-based signatures (HBS) as part of the post-quantum cryptography development effort. The two schemes were developed through the Internet Engineering Task Force: 1) XMSS, specified in Request for Comments (RFC) 8391 in May 2018, and 2) LMS, in RFC 8554 in April 2019. Background HBS schemes were the topic for a session of talks during the first public workshop on...
