Today, with the proliferation of the Internet of Things (IoT), the use of sensors is widely extended to domains as diverse as health, support and automation of industrial processes under the paradigm of Industry 4.0, traffic control, smart cities, monitoring of transport fleets, among many other applications. A problem that emerges from these scenarios is that both the data that circulates through sensor ecosystems, as well as that which is temporarily stored by these sensors, may eventually be subject to intervention by malicious users, generating: (1) a negative impact on the privacy, integrity and confidentiality of user and system data; and (2) compromise the security of the sensor nodes to execute malicious actions on a physical or digital environment, impacting on the safety of people, and economically on companies and communities. In this article, we introduce a pattern for the architectural design of a secure sensor node that characterizes the problem and helps architects solve it using a reusable, adaptable, and extensible solution. This pattern describes a Secure Sensor Node, a Cyber-Physical System (CPS) whose purpose is to obtain, store and subsequently transmit data securely from a physical environment, to other nodes or Information Systems.
