Methods and systems for flattened electronic signatures

Abstract

Systems, methods, and computer products for flattening electronic signatures, such as the signatures used for DNS zone signing keys. Associated operation may include: obtaining a first electronic signature on a mid-level public key and information associated therewith, wherein the first electronic signature is validatable by a high-level public key; obtaining a low-level public key and information associated therewith; generating a second electronic signature on the low-level public key and the information associated therewith, wherein the second electronic signature is validatable by the mid-level public key; and constructing a third electronic signature comprising the mid-level public key, the information associated therewith, the first electronic signature and the second electronic signature, wherein the third electronic signature is validatable by the high-level public key. Also included are systems, methods, and computer products and media for validating an electronic signature, such as a flattened electronic signature.
