Get Authorized Private Keyword Search Algorithm Form

Searchable encryption (SE) is an encryption mechanism that allows search operations over encrypted data. There are two types of SE schemes: Symmetric Searchable Encryption (SSE) and Public-Key Searchable Encryption (PKSE).

Homomorphic encryption is for doing calculations on encrypted data (like adding up ballots in an online voting system), while Searchable Encryption is used, as the name suggest, to search for some key term in an encrypted record (like a medical record).

In a PEKS-IBE scheme, a sender encrypted text to a cloud server and then the receiver identifies himself to PKG. He generates a trapdoor with his private key and then sends trapdoor to cloud server. Finally, the cloud server performs the keyword search operation.

Searchable encryption enables you to search encrypted records without decrypting the entire database. This is accomplished using beacons, which create a map between the plaintext value written to a field and the encrypted value that is actually stored in your database.

There are two types of encryption in widespread use today: symmetric and asymmetric encryption.

Searchable encryption is a technique that allows authorized users to search encrypted data without decrypting it. This is done by indexing the data in such a way that it can be searched without compromising the security of the data.

3 Searchable encryption (SE) schemes. SE schemes, considered as a server-side privacy enhancing technique, enable users to delegate keyword search capabilities over encrypted data contents to remote storage servers without disclosing any plaintext keyword (Song et al., 2000; Curtmola et al., 2006).
