"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, we propose the first generic construction of puncturable signature from identity-based signature by...
