Accountable Data Sharing Scheme Based on Blockchain and SGX

Nowadays, data has been more intensive and collaborative than in the past. In this paper, we propose a new accountable data sharing scheme based on blockchain and SGX, in which data subscription undeniable. By utilizing blockchain, the records of users data sharing acts are tamper-resistant, and our scheme no longer needs a trusted third party. SGX ensures the confidentiality of sharing data.
