Always Encrypted

Always Encrypted is a feature designed to protect sensitive data, such as credit card numbers or national identification numbers (e.g. U.S. social security numbers), stored in Azure SQL Database or SQL Server databases. Always Encrypted allows clients to encrypt sensitive data inside client applications and never reveal the encryption keys to the Database Engine ( SQL Database or SQL Server). As a result, Always Encrypted provides a separation between those who own the data (and…

Trusted Cloud

Established: August 31, 2015

The Trusted Cloud project at Microsoft Research aims to provide customers of cloud computing complete control over their data: no one should be able to access the data without the customer’s permission. Even if there are malicious employees in the cloud service provider, or hackers break into the data center, they still should not be able to get access to customer data. Trust model: We use a non-hierarchical trust model. That is, we don’t want…

Always Encrypted/Cipherbase

One of the barriers to adoption cloud database technologies such as SQL Azure is data security and privacy. Data is a valuable asset to most organizations and storing the data in the cloud is often perceived as a security risk. This project investigates encryption as a mechanism to address such data security concerns. In particular, the goal of the project is to research, design, and build a comprehensive database system that supports encryption as a first class citizen. The desired functionality includes: (1) storing encrypted data, (2) issuing encrypted queries and getting back encrypted results. Our goal is to support all sophisticated features of a DBMS such as complex queries, indexes, transactions and stored procedures while maintaining strong security, (3) enabling automated migration of database applications to the cloud.
