The ISO/IEC/IEEE 21451 standards provide the communication and information models to facilitate access of smart sensor to a network.ISO/IEC/IEEE 21451-1-4 standard aims to propose a solution using Extensible Messaging and Presence Protocol (XMPP) to transport message over sensor networks.Ensuring security of communications over XMPP is one of the most important issues in ISO/IEC/IEEE21451-1-4 sensor networks.In this paper, we propose a security mechanism that deals with the requirements of authentication, integrity, confidentiality, nonrepudiation and access control.The XMPP based communications in ISO/IEC/IEEE 21451 sensor networks utilize the username/password security token as well as integrated publish/subscribe(pub/sub) and role based access control (RBAC) technologies.Based on the proposed mechanism, ISO/IEC/IEEE 21451 messages are exchanged based on publish/subscribe model using extended security Simple Object Access Protocol (SOAP) over XMPP until released.To begin with, the application associates with sensor via authentication towards both sides using One-Time Password (OTP).Operation access control grants nodes roles with proper permission as publisher or subscriber in the communication.Messages based on extended SOAP over XMPP with security design ensure the communication security.After content is exchanged, communication release needs node authentication again.An instance is the model based on I SO/IEC/IEEE 21451-1-4 to secure the XMPP-based communication in sensor network.The result supports the feasibility of the security mechanism for XMPP based ISO/IEC/IEEE 21451 sensor networks.
