In the Ubiquitous Electric Internet of Things (UEIoT), the terminals are very easy to be accessed and attacked by attackers due to the lack of effective monitoring and safe isolation methods. Therefore, in the implementation of UEIoT, the security protection of terminals is particularly important. Therefore, this paper proposes a dual-system design scheme for terminal active immunity based on trusted computing. In this scheme, the terminal node in UEIoT is composed of two parts: computing part and trusted protection part. The computing component and the trusted protection component are logically independent of each other, forming a trusted computing active immune dual-system structure with both computing and protection functions. The Trusted Network Connection extends the trusted state of the terminal to the network, thus providing a solution for terminal secure access in the UEIoT.

With the rapid increasing IPv6 network traffic, some network process systems like DPI and firewall cannot meet the demand of high network bandwidth. Flow table based on hash is one of the bottlenecks. In this paper, we measure the characteristics of IPv6 address and propose an entropy based revision hash algorithm, which can produce a better distribution within acceptable time. Moreover, we use a hierarchical hash strategy to reduce hash table lookup times further more even in extreme cases.
