Abstract
The Internet of Things (IoT) serves as a crucial tool supporting smart lifestyles. As a significant application of IoT, the speed and security of transaction processing in a global cold chain logistics system have garnered considerable attention. Addressing these two issues, this paper introduces the self-management chameleon hash with double-auditability and revocability (SCHDR). Our redactable blockchain scheme is based on this chameleon hash function. We implement a self-management mechanism with a random value switching technique based on bilinear pairing and combine dual long-term trapdoor keys and label-binding technologies to achieve a double-auditability mechanism. We also effectively correct malicious rewriting behaviors and revoke the permissions for malicious modifications. The security of our scheme is based on the Bilinear Diffie-Hellman (BDH) assumption, and experiments demonstrate that our scheme possesses high efficiency. Furthermore, our proposal can also be applicable to other IoT applications with similar security requirements.
