Sensor networks are ad hoc mobile networks that include sensor nodes with limited computational and communication capabilities. They have become an economically viable monitoring solution for a wide variety of applications. Obviously, security threats need to be addressed and, taking into account its limited resources, the use of lightweight authentication is strongly recommended. In this paper, a lightweight authentication model for wireless sensor networks composed of a key management and an authentication protocol is presented. It is based on the use of trusted primitives with very low computational requirements, which obtains better results than other proposals in the literatures.
