WebJan 25, 2024 · In SEA-BREW, sensors, actuators, and users can exchange encrypted data via a cloud server, or directly via wireless if they belong to the same WSAN. We formally prove that our scheme is secure also in case of an untrusted cloud server that colludes with a set of users, under the generic bilinear group model. WebWe offer an exposition of Boneh, Boyen, and Goh’s “uber-assumption” family for analyzing the validity and strength of pairing assumptions in the generic-group model, and augment the original BBG framework with a few simple but useful extensions.

Webgeneric bilinear group model. We show by simulations that our scheme requires a constant computational overhead on the cloud server with re-spect to the complexity of the access control policies. This is in contrast to state-of-the-art solutions, which require instead a linear computational overhead. 1 Introduction Weban interactive assumption (justi ed in the generic bilinear group model), which again closely mirrors the underlying signature scheme itself. (This can be viewed as providing a proof of the scheme only in the generic group model.)
