Abstract
A method and computer architecture for securely sharing information with an arbitrary set of users in end-to-end fashion. A secure data sharing system includes clients and servers. Client programs running on specific client computers encrypt plaintext data and cryptographically bind the decryption of the encryption key to policy information that contains rules about a permitted decryption operation access. Other clients decrypt the encrypted data shared by the original client by proving to the server their identity and in return receiving cryptographic material.
