Cloud storage service permits data owners to store their encrypted content in the cloud storage servers and provide multiple users the authority to get access to the content. In this paper, we have proposed and evaluated a Secure lightweight Multi-User Searchable Encryption Scheme (SLMSES) for cloud storage. SLMSES achieves the requirement of small search time, concise index, and efficient user authorization. The scheme introduces a third party Manager which allows the users to subscribe tp data owners and get access to their files. The other job is to reduce the workload in the cloud by delegating their task of keyword searching. SLMSES employs the concept of bucketization for storing the files in the cloud. This allows the fast search for Manager as well as the cloud by narrowing the search space. Implementation and performance evaluation is conducted, which indicates that SLMSES is efficient and ready to be deployed, where subscriber base is large an stable.
