BigSecret: A Secure Data Management Framework for Key-Value Stores
Data storage is one of the most popular cloud services, and is therefore offered by most service providers. Among the various cloud based data storage services, keyvalue stores has emerged as a popular option for storing and retrieving billions of key-value pairs. Although using such cloud based key-value store services could generate many benefits, companies are reluctant to utilize such services due to security concerns. For example, if keys are used to represent social security numbers of health insurance customers, and values are their medical claim details, then outsourcing such keyvalue pairs to a public cloud could create significant privacy and security risks.
