A Password-Based Access Control Framework for Time-Sequence Aware Media Cloudization

Haiyan Wang, Peng Cheng Laboratory
Abstract

The time sequence-based outsourcing makes new demands for related access control continue to grow increasingly in cloud computing. In this paper, we propose a practical password-based access control framework for such media cloudization relying on content control based on the time-sequence attribute, which is designed over prime-order groups. First, the scheme supports multi-keyword search simultaneously in any monotonic boolean formulas, and enables media owner to control content encryption key for different time-periods using an updatable password; Second, the scheme supports the key self-retrievability of content encryption key, which is more suitable for the cloud-based media applications with massive users. Then, we show that the proposed scheme is provably secure in the standard model. Finally, the detailed result of performance evaluation shows the proposed scheme is efficient and practical for cloud-based media applications.
