TY - EJOU AU - Elamparithi, Gokulakannan TI - Resilient Service Authentication for Smart City Application Using IoT T2 - Intelligent Automation \& Soft Computing PY - 2023 VL - 36 IS - 1 SN - 2326-005X AB - Internet of Things (IoT) support for smart city systems improves service scales by ignoring various user congestion. People are looking for different security features for reliable and robust applications. Here, the Permanent Denial of Service (PDoS) problem arises from improper user identification. This article introduces the Service-Reliant Application Authentication (SRAA) to prevent PDoS attacks in a smart area of the city. In this authentication method, the security of the application is ensured through the distribution of guarded access. The supervised access distribution uses user interface features and sync with the user device. Abnormality in linking user device, application, and authentication is seen in Back Propagation (BP) readings. BP learning reduces given weights based on abnormalities trained during the access distribution process. The oddity is reflected in the sequence from previous training sessions to ensure consistent synchronization of distributed services. From PDoS, the web device displays a few unattended loads on the service, which reduces service failure. The effectiveness of the proposed verification method is verified using delays to verify metric accuracy, false standard, sync failure, and bit rate.
