Semantic Searchable Encryption Scheme based on Lattice in Quantum-era
"... Abstract. When data is outsourced to a remote storage server, search-able encryption plays an important role to protect data privacy while allowing users to retrieve data in the massive ciphertext. As far as we know, most of the existing searchable encryption schemes work based on the bilinear map. ..."

Searchable Encryption for Outsourced Data
"... Abstract. Two sets of privacy requirements need to be fulfilled when a company’s accounting data is audited by an external party: the company needs to safeguard its data, while the auditors do not want to reveal their investigation methods. This problem is usually addressed by physically isolating d ..."

data and auditors during the course of an audit. This approach however no longer works when auditing is performed remotely. In this paper we present an efficient construction for a searchable encryption scheme for outsourcing data analytics. In this scheme the data owner needs to encrypt his data only
Non-Malleable Cryptography
- SIAM Journal on Computing
, 2000
"... The notion of non-malleable cryptography, an extension of semantically secure cryptography, is defined. Informally, in the context of encryption the additional requirement is that given the ciphertext it is impossible to generate a different ciphertext so that the respective plaintexts are related. ..."

Searchable Encryption with Secure and Efficient Updates
- in CCS’14. ACM
"... Searchable (symmetric) encryption allows encryption while still enabling search for keywords. Its immediate applica-tion is cloud storage where a client outsources its files while the (cloud) service provider should search and selectively retrieve those. Searchable encryption is an active area of re ..."

Either they deteriorate from semantic security to the security of deter-ministic encryption under updates, they require to store in-formation on the client and for deleted files and keywords or they have very large
Optimal Asymmetric Encryption
, 1994
"... Given an arbitrary k-bit to k-bit trapdoor permutation f and a hash function, we exhibit an encryption scheme for which (i) any string z of length slightly less than k bits can be encrypted as where r= is a simple probabilistic encoding of z depending on the hash function; and (ii) the scheme ca ..."

Multi-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. 1 ..."

Searchable encryption revisited: Consistency properties, relation to anonymous IBE, and extensions
, 2005
"... We identify and fill some gaps with regard to consistency (the extent to which false positives are produced) for public-key encryption with keyword search (PEKS). We define computational and statistical relaxations of the existing notion of perfect consistency, show that the scheme of [7] is compu ..."

Given an arbitrary k-bit to k-bit trapdoor permutation f and a hash function, we exhibit an encryption scheme for which (i) any string x of length slightly less than k bits can be encrypted as f(rx), where rx is a simple probabilistic encoding of x depending on the hash function; and (ii) the scheme ..."

Searchable symmetric encryption (SSE) enables a client to outsource a collection of encrypted documents in the cloud and retain the ability to perform keyword searches without revealing information about the contents of the documents and queries.

Searchable Keyword-Based Encryption
