摘要：Despitetaking into the consideration of benefits of cloud computing data, proprietors are developingmore priority to put their data in the cloud. Records in the cloud should be encrypted before outsourcing. Consideringthe large network traffic and size of the data it is necessary to allow multiple keywords in the search request to getappropriate results. Currently, the mechanism of search encryption is mainly focusing on the limited keywords. In thepresent paper, for the first time, we are introducing multi-keyword ranked search over encrypted data in the cloudcomputing (MRSE) by considering privacy. For multi-keyword search mechanism on the cloud, we choose the mostsimilar “Coordinate matching” i.e., the maximum similar results to capture the search query. Initially, the idea proposedfor the MRSE based on secure inner product computation, it gives couple of significantly improved MRSE schemes toachieve various stringent privacy requirements in two distinct threat models.
