Abstract: A data set shared by multiple nodes is encrypted. The data set can be split into independent records. The records can be encrypted and shared independently, without the need to modify and transmit the full data set. Although the records are encrypted with their own encryption key, they are all accessible by a single authentication method.

Abstract: A trust relationship can be established between two or more identities without the need of a certificate authority. Trust relationships between identities can be maintained in a distributed ring of trust between two or more identities. The distributed ring of trust can be on a signed identity list. A node desiring to add an identity to the ring of trust sends a request to a member of the ring of trust. The receiving member can determine whether or not to approve the request. In some aspects, approval can be based on a previously shared key or a two-party verification. Upon approval, the requested identity is added to a trusted identity list indicating identities associated with current members of the ring of trust. The updated trusted identity list can then be distributed to the members of the ring of trust.
