Abstract: Aimed at solving the problem that sensitive data was subjected to unauthorized access and illegal tampering during data processing in cloud computing environment, a new approach called blind data processing based on trusted computing mechanisms was proposed. First, the root of trust in cloud computing environment was established by using trusted platform module(TPM) to ensure that the sensitive data was bound to a particular state of a cloud computing system. Then, the blind data processing environment was constructed. The messages transmitted over the cloud were encrypted by using TPM. The system integrity was measured and the remote attestation was carried out. Data migration from the source to the target side was completed by using elliptic curve cryptographic algorithms. The analysis showed that the secure execution environment for data processing in cloud computing was provided by the proposed approach.

Key words: cloud computing, trusted computing, trusted platform module, integrity measurement, blind data processing
