The confidentiality of JavaScript Object Notation (JSON) message data is secured using an encryption scheme. The encryption scheme implements a JSON encryption syntax, together with a set of processing rules for creating encrypting arbitrary data in JSON messages in a platform/language independent manner. A method for encrypting a data item in a JSON message begins by applying an encryption method and a key to the data item to generate a cipher value. A data object is then constructed that represents an encryption of the data item. The data item in the JSON message is then replaced with the data object, and the resulting modified JSON message is then output from a sending entity. At a receiving entity, information in the data object is used to re-generate the data item, which is then placed back in the original message.

Method and system for encrypting JavaScript object notation (JSON) messages

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.
