摘要
A method and system for access-controlled decryption in big data stores is provided. In an implementation, a system provides a method for encryption that stores meta-information about sensitive data elements being encrypted in a big data store, such as a Hadoop system, in which the bulk of the data may remain unencrypted. In an implementation, the system reads the stored meta-information at decryption time to determine where the encrypted data is within a large and unencrypted file system, and to determine whether or not an individual user has access rights to decrypt a given element of sensitive data. The system allows fine-grain control over access rights to sensitive data during decryption.
