Review on Key-Aggregate Searchable Encryption (KASE) for Group Data Sharing
An efficient cryptographic approach for data sharing where data is shared among a group of users as Data sharing is an important functionality in cloud storage. How to securely and efficiently share a collection of data related to any subject areas with others in cloud storage. Development of new novel concept of KeyAggregate Searchable Encryption (KASE). This concept is implemented through dev...
متن کاملMulti-Key Searchable Encryption
We construct a searchable encryption scheme that enables keyword search over data encrypted with different keys. The scheme is practical and was designed to be included in a new system for protecting data confidentiality in client-server applications against attacks on the server.
متن کاملPublic Key Searchable Encryption without Random Oracle ⋆
This article is described a new Public Key Encryption with Keyword Search (PEKS) scheme, which is semantically secure against chosen keyword attack, without assuming random oracle. The security of our scheme depends on the complexity assumption of Strong Diffie-Hellman (SDH). The computation operation for constructing cipher text and trapdoor of keyword is simpler than the most schemes introduc...
متن کاملKey Aggregate Searchable Encryption for Group Data Sharing Via Cloud Data Storage
the ability of preferentially sharing encrypted data with unlike users through public cloud storage might really ease security distress, by possibility data disclose in the cloud. A key test to design such encryption idea lies in the well-organized management encryption keys. The preferred flexibility of allocating any group documents with any group of users by attaining weightage different enc...
متن کاملSearchable encryption
We built a system supporting encrypted substring search of a text document. The user can encrypt and upload files to a server. The client can also query the server to ask whether an encrypted file contains a particular string of characters. The query, like the file, is not sent in plaintext but is encrypted or hashed. The server should be able to respond correctly to queries without learning th...
