 Infrastructure&description=Internet of Things (IoT) is a promising technology which has been widely used in different application fields such as warehouses, Smart Grids, public security, intelligent buildings and so on, following the progress in sensors, wireless communication and embedded systems. IOT gateway plays a significant responsibility in IoT as it can be considered as the bridge between sensor network and traditional communication network with their Internet applications. This paper gives an insight view to the design and realization challenges to localize an embedded security center into the IoT gateway nodes which connects Wireless Sensor Networks (WSN) to the Internet. The main goal is to protect the data of IoT gateway (needed for its operation) as well as its functionality and accessibility. The suggested embedded security center must responds to many objectives, it should ensure that the administrative information exchanged is correct and undiscoverable, the source is who he claims to and the system is robust and available. The proposed gateway security center consists of two ciphering methods (Advanced Encryption Standards (AES) & Rivest Cipher 4 (RC4)) to provide data encryption to the whole path from the WSN nodes to the server, a Hashed Message Authentication Code (HMAC) function to provide message integrity and authentication between the gateway and the server, a keys generation module, bidirectional entity authentication and an embedded Intrusion Detection System (IDS) to defend against internet attacks. The proposed defense strategies took into account the embedded nature of a IoT gateway and hence the recommended solutions make a compromise between highly secured and good performed system.&picture=http://www.aascit.org/aascit/decorators/img/journal/915.jpg)
