Abstract
Increasing privacy consciousness has popularized the use of end-to-end encryption (E2EE). In this paper, we discuss the security of SFrame, an E2EE mechanism proposed to the Internet Engineering Task Force for video/audio group communications over the Internet. Despite being a quite recent project, SFrame has been deployed in several real-world applications. The original specification of SFrame is evaluated herein to find critical issues that can cause impersonation (forgery) attacks with a practical complexity by a malicious group member. Further investigations have revealed that these issues are present in several publicly available SFrame implementations. Therefore, we provide several countermeasures against all the proposed attacks and considerations from performance and security perspectives towards their implementation.
期刊介绍：
Journal of Information Security and Applications (JISA) focuses on the original research and practice-driven applications with relevance to information security and applications. JISA provides a common linkage between a vibrant scientific and research community and industry professionals by offering a clear view on modern problems and challenges in information security, as well as identifying promising scientific and "best-practice" solutions. JISA issues offer a balance between original research work and innovative industrial approaches by internationally renowned information security experts and researchers.
