The second level is network layer. Network layer is responsible for the reliable transmission of information from perceptual layer, initial processing of information and classification. In this layer the information transmission is relied on several basic networks, which are the internet, mobile communication network, satellite nets, wireless network, network infrastructure and communication protocols.
The third level is support layer. Support layer sets up a reliable support platform for the application layer. On this support platform all kind of intelligent computing powersare organized through network grid and cloud computing. It plays the role of combining application layer upward and network layer downward.
The application layer is the topmost and terminal level. Application layer provides the personalized services according to the needs of the users. Users can access the internet of thing through the application layer interface using television,personal computer or mobile equipments. Network security and management play an important role in above each level.

VI. SECURITY FEATURES

a) Perceptual Layer:

Usually perceptual nodes are short ofcomputer power and storage capacity because they are simple and have less power. Therefore it is not possible to apply frequency hopping communication and public key encryption algorithm to security …show more content…
The level of security within the device will vary depending upon the nature of the protected content and the kind of application. The architecture should provide physical protection to secret keys by keeping the components like secure ROM, which is handling the secret keys inside the secure SoC. The Secure Bootloader should ensure that the device boots up with the genuine OS. Secure ROM, secure runtime environment, secure memory management are the prime focus for inbuilt
