Cryptography Based Dynamic Multi-Keyword Ranked Search Using ECC/B+TRE
International Journal of Security and Its Applications, 2015Today, Cloud computing is becoming a household technology. In cloud, a shared pool of computing resources can be accessed on demand through internet and web applications. Since outsourced data is in third party premises i.e. cloud, accountability of user data is paramount.

Hierarchical Semantic Approximate Multi-keyword Ranked Search over Encrypted Data
2018With the rapid development of Cloud Computing, how to improve users search experience over encrypted data just like plaintext search has become a challenging task. In this paper, we propose a hierarchical semantic approximate multi-keyword ranked search (HSAMS) scheme over encrypted data. Performance analysis is demonstrated that our proposed scheme is

Two-Step-Ranking Secure Multi-Keyword Search over Encrypted Cloud Data
2012 International Conference on Cloud and Service Computing, 2012To protect privacy of users, sensitive data need to be encrypted before outsourcing to cloud, which makes effective data retrieval a very tough task. In this paper, we proposed a novel order-preserving encryption(OPE) based ranked search scheme over encrypted cloud data, which uses the encrypted keyword frequency to rank the results and provide ...

Secure and Efficient Multi-keyword Ranked Search over Encrypted Cloud Data
Advanced Science and Technology Letters, 2014With the development of cloud computing, the sensitive information of outsourced data is at risk of unauthorized accesses. To protect data privacy, the sensitive data should be encrypted by the data owner before outsourcing, which makes the traditional and efficient plaintext keyword search technique useless.

An Improved Multi-Keyword Ranked Search over Encrypted Cloud Data
2017 4th International Conference on Information Science and Control Engineering (ICISCE), 2017Documents encrypted on the cloud servers can improve security, it also brings about a challenging question for secure query. We use the vector space model (VSM) to obtain the similarity of the documents. In this paper, we use a secure method to support multi-keyword parallel query, which the improved multi-tree [1] can storage the vector value and ...

Semantic-aware multi-keyword ranked search scheme over encrypted cloud data
Journal of Network and Computer Applications, 2019Abstract Traditional searchable encryption schemes mostly adopt the TF-IDF (term frequency - inverse document frequency) model which ignores the semantic association between keywords and documents. It is a challenge to design an effective and secure semantic-aware search scheme.
