Professor Zhao Mang from the School of Cyber Science and Engineering at Wuhan University has had his latest research on real-time group communication protocols selected for presentation at Crypto 2026, set to be held from Aug 17 to 20 in Santa Barbara, United States.

His paper, On the State-Compromise Security of End-to-End Real-Time Group Communication, addresses critical security challenges faced by popular platforms such as Zoom, Microsoft Teams, and Cisco Webex.

The research introduces the world’s first comprehensive end-to-end security framework for real-time group communication, tackling dual threats from malicious servers and state compromise.

Key security properties outlined include perfect forward secrecy within sessions, self-healing security after state compromise, and authorization security resilient to such compromises.

The team also introduces a novel cryptographic primitive, the Multi-Recipient Authenticated Key Encapsulation Mechanism (maKEM), which supports the design of communication protocols and serves as a foundational tool for secure multiparty communication and various types of group encryption.

The researchers have established their confidentiality and authenticity security standards, providing secure implementations in the random oracle model and the standard model.

It lays the theoretical and technical groundwork for the next generation of high-security audio and video communication systems, with significant implications for remote collaboration, critical infrastructure communication, and privacy protection applications.
