Enabling Efficient Threshold Signature Computation via Java Card API
Antonín Dufka, Petr Švenda · 2023
Threshold signatures are becoming an increasingly popular method of signing key protection, primarily due to their ability to produce signatures that require the cooperation of multiple parties yet appear indistinguishable from a regular signature. This unique feature allows for their easy integration with existing systems, making them highly desirable in applications like national identity systems and transaction authorization, where they are being gradually deployed; their growing importance is further attested by NIST’s recently initiated efforts to standardize threshold schemes [19].
