Achieving Scalability with Data Owner Anonymity in Cloud Access Control
Journal Title: Transactions on Networks and Communications - Year 2017, Vol 5, Issue 2
Abstract
Cloud computing is a trending technology that enables subscribing organizations to outsource computations and storage, and eliminates the need of purchasing and maintaining the equipment by the organizations themselves. However, it is very challenging to maintain the privacy and security of data especially when the number of users grows dramatically. This paper focuses on achieving a high level of scalability to the cloud, allowing fine-grained access control, preserving the anonymity of the data owner and enabling the end user to verify the integrity of the data uploaded to the cloud. In order to achieve this, this paper proposes an effective scheme that uses Ciphertext Policy Attribute Based Encryption (CPABE) combined with identity-based encryption (IBE), and introduces a security mediator which signs files on behalf of the data owner to preserve the data owner’s anonymity from the cloud. This scheme allows the end user to check the integrity of the data on the cloud.
