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 ...
WebGenerally, signature schemes that are secure against key exposure attacks present a limited window of time within which the attacker can produce a valid forgery, e.g., the time period when key exposure occurs in the case of [13,14,20–22].
