Abstract
The evolution of 5G and 6G networks has enhanced the ability of massive IoT devices to
provide real-time monitoring and interaction with the surrounding environment. Despite recent
advances, the necessary security services, such as immediate and continuous authentication, high
scalability, and cybersecurity handling of IoT cannot be achieved in a single broadcast authentication
protocol. This paper presents a new hybrid protocol called Hybrid Two-level µ-timed-efficient stream
loss-tolerant authentication (Hybrid TLI-µTESLA) protocol, which maximizes the benefits of the
previous TESLA protocol variants, including scalability support and immediate authentication of
Multilevel-µTESLA protocol and continuous authentication with minimal computation overhead of
enhanced Inf-TESLA protocol. The inclusion of three different keychains and checking criteria of the
packets in the Hybrid TLI-µTESLA protocol enabled resistance against Masquerading, Modification,
Man-in-the-Middle, Brute-force, and DoS attacks. A solution for the authentication problem in the
first and last packets of the high-level and low-level keychains of the Multilevel-µTESLA protocol
was also proposed. The simulation analysis was performed using Java, where we compared the
Hybrid TLI-µTESLA protocol with other variants for time complexity and computation overhead at
the sender and receiver sides. We also conducted a comparative analysis between two hash functions,
SHA-2 and SHA-3, and assessed the feasibility of the proposed protocol in the forthcoming 6G
technology. The results demonstrated the superiority of the proposed protocol over other variants
in terms of immediate and continuous authentication, scalability, cybersecurity, lifetime, network
performance, and compatibility with 5G and 6G IoT generations.
