Blockchain-Aided Searchable Encryption-Based Two-Way Attribute Access Control Research

In the Internet of Things (IoT), data sharing security is important to social security. It a huge challenge enable more accurate and secure access by authorized users. Blockchain control schemes are mostly one-way control, which cannot meet need for ciphertext search, two-way confirmation users data, transmission. Thus, this paper proposes blockchain-aided searchable encryption-based attribute scheme (STW-ABE). The combines key search. particular, meets requirement mutual between data. search avoids information leakage during transmission, thus improving overall efficiency sharing. Moreover, user keys generated coalition blockchain. Besides, pre-decryption outsourced cloud servers, reducing computing pressure on adapting needs lightweight in IoT. Security analysis proves that our under chosen-plaintext attack chosen keyword attack. Simulations show cost encryption decryption, token generation, preferable.
