Searchable Keyword-Based Encryption
To solve the problem of searching on encrypted data, many keyword search schemes have been proposed in recent years. The goal of such schemes is to enable a user to give an untrusted storage server the ability only to test whether an encrypted document contains a few keywords without learning anything else about the document. In this paper, we are concerned with decrypting the searched results ...
متن کاملA multi-user searchable encryption scheme with keyword authorization in a cloud storage
Multi-user searchable encryption (MSE) allows a user to encrypt its files in such a way that these files can be searched by other users that have been authorized by the user. The most immediate application of MSE is to cloud storage, where it enables a user to securely outsource its files to an untrusted cloud storage provider without sacrificing the ability to share and search over it. Any pra...
متن کاملSearchable Encryption with Keyword-Recoverability
Searchable encryption has many applications including email systems and storage systems. The usefulness of searchable encryption derives from its support of keyword-testability. Keyword-testability means that a receiver of a ciphertext can test whether the ciphertext contains a specific keyword. Recently, Bellare et al. suggested an efficientlysearchable encryption scheme with keyword-recoverab...
متن کاملMulti-user Searchable Encryption in the Cloud
While Searchable Encryption (SE) has been widely studied, adapting it to the multi-user setting whereby many users can upload secret files or documents and delegate search operations to multiple other users still remains an interesting problem. In this paper we show that the adversarial models used in existing multi-user searchable encryption solutions are not realistic as they implicitly requi...
متن کاملSearchable Encryption and Fuzzy Keyword Search in Cloud Computing Technology
Cloud computing is a technology that uses the internet and central remote servers to keep up data and applications. As becomes more mature, many organizations and individuals are attracted in storing more accessible data e.g. personal data files, company related information in the cloud. This technology allows for much more efficient computing by centralizing storage, memory, processing and ban...
