Abstract
A machine-implemented method for signing a JSON message begins by constructing a reference element for each data object in the JSON message. The data object is identified by a reference identifier that includes a pointer to a digest method, and a digest generated by applying the digest method to the data object. Then, a signature information element is constructed for reference elements corresponding to data objects in the message. The signature information element includes a pointer to a signature method, as well as one or more reference elements, or a canonical form of the one or more reference elements. Then, a signature element is constructed that includes the signature information element, and a signature value generated by applying the signature method to the signature information element. The signature enables a sending entity to generate a digest on a JSON message and to secure the digests using a signing key.
