A privacy protection solution for the balance of performance and security in cloud computing

Abstract

In order to strengthen users’ confidence to upload the private data to cloud platform, existing ways stressed too much on the security. However, cloud computing was an open and distributed environment, and it should provide highly robust, security and quality service to users. So it was necessary to balance the performance and security in cloud platforms, and one hybrid privacy protection solution was proposed with KP-ABE and CP-ABE. This way chosen different way to encrypt the privacy information based on user attributions according to cloud service business type. Finally, this hybrid solution was verified by the case of campus cloud environment.
