Communication security is one of the key component of Internet of Things. Now we can communicate with smart device, such as microwave oven, camera, and control it using App in our smart phone, but due to the poor computing power of smart device, it tends to be intractable to protect this communication from attack. By analyzing the security threats faced during the process of smart device and App authenticating each other’s identity, this paper proposed a lightweight transfer protocol for smart device, and introduced “Authentication Center” to help with authentication for smart device and App. In consideration of poor computing power of smart device, the lightweight protocol achieves effective reduction of network resource usage. Acting as a hub, the Authentication Center does the heavy certification and authorization work as well as the management of smart device. This protocol can protect data confidentiality, data integrity against replay attack, man-in-the-middle attack by ensuring the identities of device and App with the help of Authentication Center.
