Signing key exposure resistance
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 … 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]. Moreover, the requirement to update keys/algorithms may alert an attacker to an unsuccessful key exposure ...

Then, we employ Agrawal’s left–right lattices and delegation … Weber a signing key exposure attack and cannot withstand this attack. Furthermore, we propose an improved RIBS scheme that provides strong unforgeability and signing key exposure resistance in the standard mod-el. In addition, the analysis results indicate that our scheme has higher computational performance and security. 2. Preliminaries
