Punam Prabha, Kakali Chatterjee . Robust Data Authentication Code for IoT Device Data Authentication in a Layered E-Healthcare System. International Journal of Computer Applications. 187, 141 ( Sep 2026), 1-14. DOI=10.5120/ijca1ff3258bd0b2
Data authentication faces severe difficulties in the layered architecture of the e-healthcare system (EHS), with risks to integrity, security, and authenticity occurring at every layer. Conventional authentication techniques often fall short in ensuring comprehensive mes- sage integrity and authenticity. In this context, introducing a robust data authentication code (RDAC) offers a strategic solution for securing healthcare information as it traverses IoT devices. RDAC works in two phases: encapsulation and decapsulation. In the en- capsulation phase, encapsulation authentication code mac1 is generated which is again validated to decapsulation authentication code mac2 in the decapsulation phase. The implementation of RDAC at the internetwork layer promises significant enhancements in security and integrity, ensuring trustworthiness and immutability of data across IoT devices. RDAC exhibits significant gains in performance parameters when compared to current solutions, such as low compilation time, small output size, economical memory usage, efficient resource use, and remarkable operational speed.
