摘要：Cloud computing is the long dreamed vision of computing as a utility, where users can remotely store their data into the cloud so as to enjoy the on -demand high quality applications and services from a shared pool of configurable computing resources. Trusted applications from untrusted components will be a major aspect of secure cloud computing. Today, many such applications require a proof of result correctness. It has been envisioned as the next generation architecture of IT Enterprise. As it becomes prevalent, more and more sensitive information are being centralized into the cloud. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, Cloud Computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. For the protection of data privacy, sensitive data usually have to be encrypted before outsourcing, which makes effective data utilization a very challenging task. With the advent of cloud computing, data owners are motivated to outsource their complex data management systems from local sites to commercial public cloud for great flexibility and economic savings. But for protecting data privacy, which obsoletes traditional data utilization based on plaintext keyword search. Multistep processing is common ly used for nearest neighbor (NN) and similarity search in applications involving high dimensional data and/or costly distance computations. Although traditional searchable encryption schemes allow a user to securely search over encrypted data through keywords and selectively retrieve files of interest, these techniques support only exact keyword search. This paper explores various secured searching algorithms such as Advanced Encryption Standard (AES), Secured Socket Layer (SSL), and Knowledge nearest Neighbor (k-NN).
