PhD Seminar • Cryptography, Security, and Privacy (CrySP) • On the Adaptive Security of Key-Unique Threshold Signatures

Please note: This PhD seminar will take place online.

In this talk, we will review the security assumptions required to prove the adaptive security of threshold signatures. Adaptive security is a strong notion of security that allows an adversary to corrupt parties at any time, and is of practical interest due to recent threshold standardization efforts. We will discuss design decisions across a range of adaptively secure threshold signature schemes in the literature, and the resulting impact on the security assumptions required to prove unforgeability when considering an adaptive adversary.
