Privacy-Preserving Keyword Search Over Encrypted Data in Cloud Computing
Search over encrypted data is a technique of great interest in the cloud computing era, because many believe that sensitive data has to be encrypted before outsourcing to the cloud servers in order to ensure user data privacy. Devising an efficient and secure search scheme over encrypted data involves techniques from multiple domains – information retrieval for index representation, algorithms ...
متن کاملPrivacy Preserving Ranked Keyword Search over Encrypted Cloud Data
We present a scheme that discusses secure rank based keyword search over an encrypted cloud data. The data that has to be outsourced is encrypted using symmetric encryption algorithm for data confidentiality. The index file of the keyword set that has to be searched is outsourced to the local trusted server where the keyword set that is generated from the data files is also stored. This is done...
متن کاملPrivacy Preserving Keyword Search over Encrypted Cloud Data
Cloud computing enables the organizations to outsource their data by providing a service model called infrastructure as a service (IaaS). In a public cloud the infrastructure is owned and managed by a cloud service provider and is located in the provider’s control. To protect the privacy of sensitive data, documents have to be encrypted before outsourcing. When the number of encrypted documents...

Cloud Computing, the long term goal of utility computing has transformed the IT industry a lot. Data constantly contain sensitive information should be secured by policies and regulation defined by various organizations. However, information on cloud always causes privacy problems. Data encryption protects privacy and confidentiality but efficiency is not ensured. Symmetric Searchable Encryptio...
متن کاملPrivacy- Preserving Keyword-based Semantic Search over Encrypted Cloud Data
To protect the privacy, sensitive information has to be encrypted before outsourcing to the cloud. Thus the effective data utilization becomes a significant challenge. Searchable encryption scheme has been developed to conduct retrieval over encrypted data. However, these schemes only support exact keyword search. Recent fuzzy search schemes mainly evaluate the similarity of keywords from the s...
