Abstract: An apparatus may include a communication interface configured to receive a first message including a first data portion and a second data portion, wherein the first data portion is associated with a security token, wherein the first data portion includes a first instance of a session key, and wherein the second data portion includes a second instance of the session key. The apparatus may also include a security component configured to perform message validation associated with the first message.

Abstract: A method of increasing communication security may include receiving, from a first computer system at a second computer system, a Constrained Application Protocol (CoAP) message, wherein the CoAP message may include authentication data. Message validation may be performed based on the authentication data, wherein the performing message validation may include determining that the CoAP message is invalid if at least one condition is not met. The method may also include performing, if the CoAP message is valid, at least one operation associated with the CoAP message.

Abstract: 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 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.
