Abstract: Cloud computing is an budding information technology of data storage, of local networks as well as software and has its advantages of scalability, reliability, high performance and comparatively low cost feasible solution contrast to committed infrastructures. In this paper, an effective encryption algorithm is proposed with the employment of advanced encryption standard (AES) encryption. Here, we modify the shift operation which highly eliminates data privacy leakage. Here, initially the data owner encrypts the searchable index with enhanced AES encryption. The storage would in the form of vector space. Subsequently, the data user will decrypt the scores and select out the top-K highest scoring files identifiers to request to the cloud server. The technique is implemented using JAVA and evaluated using standard metrics.
Keywords: cloud computing; decryption; query retrieval; advanced encryption standard; AES; cryptography; multi-keyword top-K retrieval; cloud data; data privacy; cloud security.
