TLDR
This paper tries to introduce a highly secure and flexible database encryption scheme allowing multiple users to perform more complex queries, including cross-table joins and still achieve acceptable performance by utilizing database's built-in indexing capabilities.Citations

Transparent Data Encryption for Data-in-Use and Data-at-Rest in a Cloud-Based Database-as-a-Service Solution
Vasily Sidorov,Wee Keong Ng +1 more
TL;DR: This paper proposes a different approach to TDE, which takes into account cloud-specific risks, extends encryption to cover data-in-use and partly data- in-motion, and is capable of executing large subsets of SQL including heavy relational operations, complex operations over attributes, and transactions.

Model of an Encrypted Cloud Relational Database Supporting Complex Predicates in WHERE Clause
Vasily Sidorov,Wee Keong Ng +1 more
TL;DR: A modular and extensible framework model of an encrypted database is introduced, which makes it possible to execute a wide range of queries, including those with complex arithmetic expressions, retaining data privacy even with an adversary gaining full access to the database server.

Practical techniques for searches on encrypted data
TL;DR: This work describes the cryptographic schemes for the problem of searching on encrypted data and provides proofs of security for the resulting crypto systems, and presents simple, fast, and practical algorithms that are practical to use today.

Executing SQL over encrypted data in the database-service-provider model
TL;DR: The paper explores an algebraic framework to split the query to minimize the computation at the client site, and explores techniques to execute SQL queries over encrypted data.
Journal ArticleDOI
Shared and searchable encrypted data for untrusted servers
TL;DR: This paper proposes an encryption scheme where each authorised user in the system has his own keys to encrypt and decrypt data and supports keyword search which enables the server to return only the encrypted data that satisfies an encrypted query without decrypting it.
Internet Security Glossary, Version 2
TL;DR: The 334 pages of entries offer recommendations to improve the comprehensibility of written material that is generated in the Internet Standards Process (RFC 2026) following the principles that such writing should use the same term or definition whenever the same concept is mentioned.

Private query on encrypted data in multi-user settings
TL;DR: The results include a set of security notions for multi-user searchable encryption as well as a construction which is provably secure under the newly introduced security notions.
