Manfred Reuternt paper shows a devastating attack against the scheme, forging a signature in ≃ 2. operations. The scheme can be rescued in a rather straightforward way by significantly raising the parameters, but this degrades its performances which do not compare anymore favorably to . In place, we suggest t最高峰 发表于 2025-3-29 10:44:53

As a result, we prove under the DDH assumption, that a straightforward variant of , which is more simple and efficient than , is secure for users. This proof relies on the subsequent result of Handschuh, Tsiounis and Yung showing equisyncope 发表于 2025-3-29 12:17:27

We also provide measures for auditability, fairness, and trustworthiness of the process. Besides cryptography, we incorporate security mechanisms that eliminPeak-Bone-Mass 发表于 2025-3-29 18:49:13

Such control can anticipate dynamic changes of the business entity. We demonstrate how to manage group entities which ar叙述 发表于 2025-3-30 06:16:59
