A Secure Collaborative Network Protocol
Hugo Lima, Roberto Samarone Araujo, Raimundo Viégas, Denis Lima do Rosário · 2016
Cloud storage services allow a simple collaborative environment in which users share their files. To perform this, users state which files they want to share and who is able to access them. Recently, Silva et al. introduced an idea that does not require users to explicitly state who is able to access their files. It allows users to share their files based on common interests. As a result, users do not need to know any information (e.g., email addresses) about each other before sharing files. Unfortunately, security is not a concern in the first scheme that implements this idea. In this paper, we proposed an improved protocol that takes security into account.
