Identity-Based Key Derivation Method for Low Delay Inter-domain Handover Re-authentication Service

Abstract

Several statistics on the factors of attacks’ proliferation revealed the scarce deployment of entity authentication mechanisms being one of the most important. Particularly, providing seamless mobile re-authentication service for real-time inter-domain handover procedures is still an open issue. This paper is focused on the re-authentication architecture and mechanisms design, aiming to low latency re-authentication services for roaming WLAN or WiMAX terminals. Authentication architecture is specified to integrate the proposed mechanisms and a novel generic key material concept is defined in addition to the current state-of-the-art. An identity-based key material derivation method is developed, relying on the multiplicative group associativity property and the intractable underlying RSA problem. Then, the required cryptographic properties are evaluated. A simple generic key material pre-distribution mechanism is proposed and the related local re-authentication protocol. Eventually, the validation of the security properties of the re-authentication protocol, as well as the functional correctness validation of the re-authentication service is performed.
