dc.description.abstract Public-key based certificates provide a standard way to prove one's identity, as certified by some certificate authority (CA). But standard certificates provide a binary identification: either the whole identity of the subject is known, or nothing is known. By using a Merkle hash tree structure, it is possible for a single certificate to certify many separate claims or attributes, each of which may be proved independently, without revealing the others. Additionally, trees from multiple sources can be combined together by modifying the tree structure slightly. This allows claims by different authorities, such as an employer or professional organization, to be combined under a single tree, without the CA needing to know (let alone verify) all of the claims. en
