Patent attributes
A first party uses a secret key to encrypt information, which is then sent through an untrusted connection to a second party. The second party, however, cannot decrypt the information on its own, and it relays the encrypted information through a secure network. The secure network includes one or more nodes linking the first and second parties through one or more trusted connections (“hops”); each hop features uses of a shared secret key unique to that hop. The first party's connection to the network (domain) receives the information relayed through the secure network by the second party, it decrypts that information according to the secret key of the first party, and it then retransmits the decrypted information to the second party using the secure hops. Techniques are provided for sharing a private session key, federated credentials, and private information.
