Accelerated Verification of an ID-based Signature Scheme for Broadcast Authentication in Wireless Sensor Networks

摘要: Broadcast authentication is a fundamental security service in wireless sensor networks (WSNs). Although symmetric-key-based µTESLA-like schemes were employed due to their energy efficiency, they all suffer from DoS attacks resulting the nature of delayed message authentication. Recently, several public-key-based have been proposed achieve immediate broadcast with significantly improved strength. While obviate vulnerability inherent schemes, signature verification time-consuming. Thus, speeding up problem considerable practical importance, especially resource-constrained environments. This paper presents an accelerated vBNN-IBS, pairing-free identity-based reduced size. A quantitative analysis demonstrates that vBNN-IBS reduces 38.62% consumption 4×4 grid-based WSN and runs 66% faster than traditional method. It also allows total be by 23.25% 25.14% compared to, respectively, IMBAS [1] EIBAS [13] ID-based schemes.
