Abstract
En 中文
Identity authentication is an essential element for industrial Internet of Things (IIoT), which guarantees secure access control for various devices. Existing authentication schemes face some security threats, including temporary secret leakage attack, key recovery attack, and forgery attack. In this article, we introduce a blockchain-based certificateless conditional anonymous authentication (BCCA) scheme specifically designed for IIoT. To optimize the authentication efficiency, BCCA employs elliptic curve design to avoid the relatively time-consuming bilinear pairing operation. Additionally, we introduce a precomputation strategy, allowing users to prepare essential materials in advance, and one-time verification support for batch signatures is applied, thus reducing authentication latency. To further enhance the security, random verification checksums are employed to counter key recovery attack, and a combination of long-term and short-term secrets is used to mitigate temporary secret leakage attack. Simulation results demonstrate that our scheme has advantages in both security and computational cost.
