As IoT is broadly used in many fields, the security of IoT is becoming especially important and critical
issues. Security and privacy are the key issues for IoT applications, and still faced with some enormous
challenges. Sensor has limited resources such as computing power, memory, battery. By means of deeply
analyzing the security architecture and features in security framework. While a number of researchers have
explored such security challenges and open problems in IoT, there is an unfortunate lack of a systematic
study of the security challenges in the IoT landscape. This special issue features recent and emerging
advances IoT architecture, protocols, services and applications. The alternative method is IoT security
gateway. In this paper, we surveyed the demands and requirements. By means of deeply analyzing the
security architecture and features, we analyzed the demands and requirements for security based on gateway
application.
