Abstract: The administration of access control and the support of keyword search are some issues which are important in
secure cloud storage system. With the use of cloud computing, data owners outsource their tricky data management
systems from local sites to the commercial public cloud to achieve flexibility and economic savings. But to protect data
privacy, sensitive data has to be encrypted before outsourcing the data, which outdated the traditional data utilization
based on plaintext keyword search. Considering a number of data users and documents in the cloud, it is mandatory to
allow multiple keywords in the search request and return documents in the order of their relevance of these keywords.
This system design will provide an efficient traceable authorization search system for secure cloud storage, which
overcomes these entire limitations- inflexible authorized keyword search, abuse of attribute secret key, inefficient
decryption.
