ABSTRACT The Internet of Things (IoT) has witnessed an explosive growth, generating vast amounts of data with numerous applications. However, safeguarding this data's security and privacy is of paramount concern. In response, this paper introduces an innovative approach that combines proxy re-encryption techniques with blockchain technology to enhance the security of data sharing within IoT networks. In our proposed framework, data owners delegate access privileges to authorized entities, known as proxies, via a secure re-encryption process. This proxy reencryption mechanism ensures that only authorized entities can decrypt and access the shared data, thus preserving data confidentiality and integrity. The blockchain serves as a decentralized, immutable ledger to record and manage access control policies and cryptographic keys.
