Patent ID: 7644266

Claim:
A method to perform operations to facilitate message security, the operations comprising: identifying a predetermined message class of an internode message, the predetermined message class identified by a message class indicator, each message class indicator mapped to a particular message security level by a security level map; an application layer of a first node mapping the particular message security level to an encryption indicator and a digital signature indicator in accordance with a security level definition; applying security to the internode message at the application layer in accordance with the encryption indicator; applying a digital signature to the internode message at the application layer in accordance with the digital signature indicator; wherein the application layer comprises an application programmed to selectively apply the particular message security level to the entire internode message as defined in the security level map; communicating the message between the first node and a second node, wherein the security of the internode message is preserved between the first node and the second node, wherein a second application operating on the second node mares the message class indicator to the particular message security level, the second application comprising the same security level map for mapping the message class indicator to the particular message security level and wherein an application layer of the second node applies the particular message security level to the internode message to implement the particular message security level; wherein a digital processing apparatus performs the operations by way of one or more of logic hardware comprising at least a processor and hardware memory.
