:Over inadvertent data leaks in the cloud there may greatly ease security concerns with different users viapublic cloud storage by the capability of selectively encrypted data sharing. In the efficient encryption keysmanagement, to designing such encryption schemes lies is a key challenge. For different documents, with any groupof users their demands different encryption keys, any group of selected documents to be used the desired flexibility ofsharing. However, for both encryption and search, to users a large number of keys the necessity of distributingsecurely and to securely store the received keys also implies those users will have and to perform search over theshared data submit to the cloud in order an equally large number of keyword trapdoors. The approach impractical forthe implied need for secure storage, complexity and communication clearly renders. In this paper, by conceptinstantiating through the scheme of a concrete KASE and proposing the concept of key-aggregate searchableencryption (KASE), we address this practical problem. In the literature this problem was largely neglected, in which alarge number of documents sharing to a user, there needs only to distribute a single key a data owner, and the useronly needs for querying the shared documents for submitting a single trapdoor to the cloud.
