Outline
To meet the demand for efficient, low-power, and secure authentication mechanisms in the safety monitoring and maintenance of rail transit equipment, this study systematically investigates the implementation of cross-domain identity authentication. First, a system architecture is designed using a super SIM card as the identity carrier, combined with Bluetooth Low Energy (BLE) technology for rapid data exchange between devices. Second, a high-efficiency anonymous identity authentication scheme integrating a blinded ECDSA algorithm is proposed. Finally, the proposed scheme is compared with supervised anonymous authentication schemes and other traditional authentication algorithms regarding computation and communication overheads. The results indicate that, compared to NIST-standard-based ECDSA and traditional ECC algorithms, the proposed scheme demonstrates superior performance in signature generation with the shortest overall runtime. Additionally, authentication efficiency is improved by 43.8% compared to supervised anonymous authentication schemes, verifying the effectiveness and feasibility of the proposed approach. These findings provide a valuable reference for intelligent security monitoring and maintenance of equipment in low-altitude economic sectors and the rail transit field.
