Signing key exposure resistance
WebIn this paper, we aim to provide a scalable revocation mechanism for attribute-based signature (ABS). Specifically, we first formally define the syntax of revocable ABS (RABS), … 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

WebIn 2014, a new security definition of a revocable identity-based signature (RIBS) with signing key exposure resistance was introduced. Based on this new definition, many scalable … WebSep 10, 2024 · Furthermore, we demonstrate that Hung et al.’s RIBS scheme is vulnerable to signing key exposure attack. To solve these problems, we construct an improved RIBS scheme with strong unforgeability and signing key exposure resistance in the standard model. Compared with previous RIBS schemes without random oracles, ...
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 ... WebFeb 5, 2015 · Cloud storage auditing is viewed as an important service to verify the integrity of the data in public cloud. Current auditing protocols are all based on the assumption that the client's secret key for auditing is absolutely secure. However, such assumption may not always be held, due to the possibly weak sense of security and/or low security settings at …

Webalso note that key exposure against the transformation key is unnecessary when the key updated is sent through via a public channel since the transformation key can be derived by anyone. On the other hand, since the user decryption. 95 key is static, it obviously cannot resist the decryption key exposure attack we. 5
