Abstract
Parties are enabled to exchange data without knowing the other party's encryption key. Cells in one party's database each form an object which is encrypted at the object level. Authentications and authorizations are incorporated into each object. An encryption management engine produces different keys for each objects. A security server database stores a key registered by one party. The in a later request by the party is compared to its registered key. A protocol and key management method allow identification and access to an appropriate key using only publicly available information. A set of data is added with a secured session key. A selected set of data is used to create a cryptographically secure Header-Tx with a secured session key and an Access Control List with an embedded security policy. Data is sent to a receiver only when authorized by the customer authentication security server.
