Problems solved by technology

[0006] (1) There are very few cloud audits that support ownership transfer in existing research, and the common data audit scheme with transferable ownership needs to be studied urgently in practical applications
[0007] (2) Existing audit solutions that support cloud data ownership migration are only aimed at the scenario of a single data holder, and do not consider the migration and audit of shared data
[0008] (3) The existing audit schemes that support the migration of cloud data ownership do not consider the issue of traceability and accountability when data is damaged, and the efficiency of the migration method is poor

Abstract

The invention belongs to the technical field of cloud computing security, and discloses an accountable shared cloud data ownership migration and auditing method and system. The accountable shared cloud data ownership migration and auditing method comprises the steps of system establishment, migratable shared auditing label generation, shared cloud data integrity auditing and shared data ownership migration. After group division, group users cooperate with each other to generate respective member keys; a plurality of users in the group spontaneously form a set, and generate a migratable and audible data label for a common data file; data auditing is performed, and data integrity is probabilistically checked through a sampling method; and the ownership migration of the common data is completed through a proxy re-signature and outsourcing calculation method. According to the method, the integrity auditing and the shared ownership migration of the cloud data can be realized at the same time, and the accountability of auditing and migration is realized by recording the data creation and ownership migration processes on a blockchain and utilizing the non-tampering property and the traceability of the blockchain.

Description

technical field [0001] The invention belongs to the technical field of cloud computing security, and in particular relates to an accountable shared cloud data ownership transfer and audit method and system. Background technique [0002] At present, cloud computing is a brand-new computing model, which has almost endless, location-independent and elastically scalable computing and storage resources. Nowadays, more and more individuals and even enterprises have become cloud users, and they can obtain cloud services on demand through online electronic devices such as mobile phones and laptops. After enjoying the cloud storage service, the overhead for these users to manage and maintain local physical devices is significantly reduced. Nevertheless, since the cloud server is not completely trusted in the real environment, the integrity of the cloud data may suffer accidental damage or intentional damage, and its security is worthy of attention. Therefore, in order to monitor th...
