Abstract

INCREASED COMMUNICATION SECURITY Authentication data may be generated and included in a Constrained Application Protocol (CoAP) message communicated from a first computer system to a second computer system. The authentication data may allow the second computer system to 5 perform message validation for verifying the authenticity of the first computer system and/or the integrity of the CoAP message. And in one embodiment, where the CoAP message includes a nonce, security can be improved by allowing the second computer system to advantageously detect and/or act on a replay attack. (Fig. 1) 10
