Specifically, we first formally define the syntax of revocable ABS (RABS), followed with a corresponding security model that considers a realistic threat called signing key exposure. Then, built on the ideas of an ABS scheme and binary data ...

WebMar 26, 2024 · Abstract. Identity-based proxy re-signature (IDPRS) is a novel cryptographic primitive that allows a semi-trusted proxy to convert a signature under one identity into another signature under another identity on the same message by using a re-signature key. Due to this transformation function, IDPRS is very useful in constructing privacy ...
