Definition ∞ Searchable symmetric encryption is a cryptographic primitive that permits users to search over encrypted data without decrypting it, using a symmetric key. The data owner encrypts their information and generates an index, which is then stored on a server. Queries are also encrypted, allowing the server to perform the search without learning the content of the data or the query.
Context ∞ SSE is a fundamental technology for privacy-preserving data storage and retrieval, particularly relevant for cloud-based services and decentralized data solutions. Its application in blockchain contexts enables confidential queries on encrypted ledger data, enhancing user privacy while maintaining data utility. Research focuses on optimizing SSE schemes for efficiency and security against various leakage attacks.
