Method and system are described for validating a digital signature. More
particularly, a signed message and a corresponding certificate are
received. The certificate is checked for validation. A validation
statement is generated, and the certificate validation and the signed
message provide a status. This status represents a request for
validation, and is provided along with a set of validations among which
such status is an element. A digest is generated using a Merkle
authentication tree corresponding to the set of validations, and this
digest is signed with a private key. Accordingly, a notary may provide
the signed digest, status and the set of validations for subsequent
confirmation of the digital signature.
