Block chain based Privacy-Preserving Authentication and Key Verification using PBDS Framework

The blockchain based Industrial Internet of Things (IIoT)
system enables secure data sharing by preserving user privacy through
decentralization and cryptographic methods. It provides privacy by
protecting data during transmission and by allowing only authorized
entities to communicate with IIoT networks. However, ensuring security
and privacy in IIoT remains challenging. Traditional methods typically
address only authentication and privacy, while static block chain
consensus mechanisms introduce significant overhead and lack adaptive
access control in dynamic environments. To overcome these challenges,
this research proposes Password Based Key Derivation Function2
(PBKDF2) integrated with Blowfish Encryption (BE) and Hash Message
along with Digital Signature named as PBDS. This method is associated
with block chain, Zero Knowledge Proof (ZKP) are employed to prevent
unauthorized access and ensure secure data sharing. PBDS provides
adaptive and fine-grained access control, enabling various untrusted
entities to flexibly and securely manage resources based on contextual
information and policy rules. Experimental results show that the proposed
PBDS achieves lower Encryption Time (ET) and Decryption Time (DT)
of 6.4513s and 5.9836s respectively.
