One-Pass Anonymous Key Distribution in Batch for Secure Real-Time Mobile Services

Key distribution is important to provide security guarantee for mobile services of Internet of Things (IoT). Traditional key distribution methods hardly provide single data server the promise to build multiple high-level secure real-time service channels simultaneously with high efficiency. In this paper we consider real-time data collecting or monitoring scenarios, which is commonly happened in health-care. In these scenarios, traditional key distribution approaches in public-key setting have difficulties on considering both security and efficiency during interactions. Besides, anonymity also shows importance during key distribution processes to keep personal privacy. In this paper we propose a secure real-time mobile service system and the corresponding security model, and novelly apply an Identity-Based Key Encapsulation Mechanism (IBKEM) in the proposed system as an instantiation that achieves one-pass anonymous key distribution in batch for mobile clients. The instantiated system shows both high-level security and efficiency in practice.
