Abstract
A data encryption service is provided over the Internet. Users specifying only authorized users' identity information can share encrypted information without sharing passwords or accessing public key certificates. A user sends data to be encrypted to a trusted EWS, along with authorization information. An encrypted data envelope including signed encrypted data blocks, authorization information, and a digital signature is returned to the user. When a second user attempts to access the data inside the encrypted data envelope, it is transmitted to the EWS. If the EWS authenticates the second user, determines that tampering has not occurred, and verifies the second user's identity against the authorization information in the data envelope, then the data are returned. The encrypted data envelope can be expressed as a raw byte stream or encoded within an HTML file to enable browser-based data envelope submission and retrieval.
