Design of SPI to I2C Protocol Converter and Implementation of Low Power Techniques

Abstract: Wireless Sensor Network (WSN) is an area of research that has various applications both for mass public and military. A wireless sensor network is composed of many sensors which can be used to monitor physical or environmental conditions, such as temperature, sound, pressure. After collecting these data they should pass this data through the network to a main location. A Sensor Node in Wireless Sensor Network lacks resources such as processing capability, memory capacity, battery power, and communication capability. Because of the limited resources on sensor nodes, the use of conventional key management techniques in wireless sensor networks is limited. Key establishment is the most important cryptographic primitive in all kinds of applications where security is a concern. Authentication and pair wise key establishment are critical in sensor networks. In this paper, we provide a survey of key management schemes in wireless sensor networks.
