Secure Group Communication Implementation and Analysis of Various Routing Techniques

This paper intricately examines the in-area overhead efficiency of Network-on-Chip (NoC) architecture, specifically employing the reconfigurable swapping router technique. Additionally, it explores the performance of the First In First Out (FIFO) routing technique within a secure group communication framework, introducing a one-round dynamic Identity-Based Authenticated Group Key Agreement (IBAAGKA) protocol. The Hardware NoC (H-NoC) design at the Register-Transfer Level (RTL) is analyzed for simulated area performance, revealing superior metrics in terms of area utilization, delay, and global request handling. The proposed H-NoC technique ensures a high level of basic execution, while the IBAAGKA protocol, implemented using the FIFO approach, guarantees secure communication without the key escrow issue. The introduced security protocols, characterized by independent key establishment, demonstrate efficiency with fewer rounds, offering robust protection against unauthorized decryption.
