Authenticating Ranked Keyword Search and Supporting Score Dynamics
Subscribe/Renew Journal
Cloud computing enables the user to remotely store their data over cloud. It economically enables the paradigm of data service outsourcing. For protecting data privacy sensitive cloud data have to be encrypted before outsourced into cloud. Traditionally, Boolean search technique is used for file retrieval. But it is not sufficient to meet effective data utilization. The problem of efficient ranked keyword search over encrypted cloud solved. The ranked search is done by Ranked searchable symmetric encryption scheme (RSSE). We explore the relevance score approach to build a searchable index which is used for easily identifying user interested keyword. We investigate, score dynamics when the content of the file be changed.
