Let’s talk about multi-party threshold schemes

Abstract: This talk will open the NIST workshop on multi-party threshold schemes (MPTS) 2020, presenting a viewpoint of the NIST Threshold Cryptography project on the potential for standardization of multi-party threshold schemes. In scope are threshold schemes for NIST-approved key-based cryptographic primitives, such as signing, encryption, decryption and key generation. As laid out in NISTIR 8214A, a necessary step moving forward is the definition of criteria for considering threshold schemes in a standardization effort. The talk will review the logic behind the workshop organization, describe its feedback-collection goal, and outline the program of ensuing talks.
