英文摘要
Due to the increasing volume of medical data, storing medical data in the cloud has become a trend of the times. With the popularity of cloud computing, how to ensure the integrity of medical data in the cloud is an urgent problem to be solved. Also, how to realize the following functions such as supporting for dynamic operation, multiuser modification, and user revocation are also further challenges for data integrity verification after fully consider the particularity of the medical scenario. In this paper, a new primitive of bi-auditing is put forward given the particularity of the medical scene. According to the different configurations and requirements of medical personnel and patients, two auditing schemes are designed to support different users along with various functions. On the one hand, a novel hash forest structure is designed to provide medical personnel with dynamic operations on data. Besides, the proposed structure supports medical personnel to perform multiuser modification operations on relevant data and supports the revocation of illegal users. On the other hand, considering the weak security awareness and low device configuration on the patient side, the key update is provided for the patient to deal with the key exposure problem. Both theoretical and experimental analyses demonstrate that the proposed scheme is secure and has a decent performance in computational overhead.
