Quick Verification and Security Integrity of Emergency Messages Communication over Wireless Network

Communication over wireless networks is increasingly vital for reliable, low-latency transmission of small messages by resource-constrained devices. These devices often struggle with the demands of implementing robust integrity security for emergency messages. Our solution, the BB-MAC (Bit by Bit Message Authentication Code) method, addresses this challenge with a quick, memory-efficient approach rooted in the Carter-Wegman structure. The key idea is to shift resource-intensive computations to idle periods, conserving critical time during latency-sensitive phases when new data must be processed. BB-MAC employs a universal hash function for Bit by Bit pre-computation of integrity security, minimizing XOR cycles during critical operations. Our research on embedded systems shows that BB-MAC outperforms recent methods in terms of delay and memory overhead, particularly for small payloads, making it a superior choice for safeguarding resource-limited devices under stringent security and latency requirements.
