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 … WebMay 1, 2024 · Definition 4 Forward Security(Key-Exposure Resilience) under Continual Leakage. An auditing protocol is l-Forward Secure(Key-Exposure Resilient) under Continual Leakage if for any probabilistic polynomial-time adversary A, the advantage of the adversary to win the above game is a negligible function in λ. 4.2.

Revocable identity-based proxy re-signature against signing key exposure

WebWe reviewed existing lattice-based RIBS schemes and found that all these schemes are vulnerable to signing key exposure. Hence, in this paper, we propose the first lattice … WebMar 26, 2024 · 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 unde signs of bipolar schizophrenia

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 … 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 ...
