Cloud computing allows the users geographically located to access data and application from a cloud which follows the pay-as-you-go financial model. This technology provides a method to enhance the capabilities dynamically without having to spend in new infrastructure or training personnel. Cloud computing promises to offer reliable services to the customer through the construction of next-generation data centers and storage technology. With its wide advantages, cloud computing has emerged as fast emergent segments of the IT. Hence data security is a major concern for cloud users. One solution to this is that user can apply encryption techniques on data before sending it to the cloud server. But encrypted data limits the server’s capability to make plaintext keyword search. Keyword search functionality that can function over the encrypted data is desirable but no information about the searched keyword or the retrieved document should not compromise in this process. Our implementation of searchable symmetric encryption proves that it is not vulnerable to such things and preserves privacy of user data and query.
