"Puncturable Signature: A Generic Construction and Instantiations" by Mei Jiang, Dung Hoang Duong et al.
Puncturable signature (PS), proposed by Bellare, Stepanovs and Waters at EUROCRYPT 2016, is a special kind of digital signature that supports a fine-grained revocation of signing capacity by updating the secret key with selective messages. Puncturable signature has many usages like asynchronous transaction data signing services and proof-of-stake blockchain protocols. Meanwhile, it is an essential building block in constructing disappearing signatures in the bounded storage model. In this paper,...
