Security of Internet of things network is difficult to manage because Internet of things devices are heterogeneous and always deployed in remote places. Based on these features, attacks against Internet of things network like distributed denial-of-service and system intrusion are easier than traditional network. In order to enhance Internet of things network’s security, in this article we propose the concept of intrinsic security to establish a trusted and autonomy Internet of things network. Intrinsic security emphasizes that network itself must be trusted and security autonomous to address the security problems which are caused by remote and heterogeneous. Based on this thought, we designed the architecture of Trusted Autonomy Security System. Trusted Autonomy Security System maintains a LAN characterized by trusted and security autonomy, in which all Internet of things network gateways formed a decentralized autonomy system to evaluate if other gateways or Internet of things devices are secure. Compared to traditional Internet of things networks, this architecture uses trusted computing technique to build the basic of security, and makes Internet of things network available to manage security automatically. In addition, the decentralized architecture could reduce security risks caused by compromise of single node in Internet of things network. With these advantages, it can be expected that this novel idea will have more development in Internet of things scenarios with high security requirements.

以内在安全性构建：可信自治安全系统

由于物联网设备异构且总是部署在偏远地区，物联网网络的安全性难以管理。基于这些特性，分布式拒绝服务、系统入侵等对物联网网络的攻击比传统网络更容易。为了增强物联网网络的安全性，本文提出了内在安全的概念，以建立一个可信、自治的物联网网络。内在安全强调网络本身必须是可信的和安全的自治，以解决远程和异构带来的安全问题。基于这一思想，我们设计了可信自治安全系统的架构。可信自治安全系统维护一个以可信和安全自治为特征的局域网，其中所有物联网网关组成了一个去中心化的自治系统，以评估其他网关或物联网设备是否安全。与传统的物联网网络相比，该架构采用可信计算技术构建安全基础，使物联网网络可以自动管理安全。此外，去中心化的架构可以降低物联网网络中单个节点被攻陷所带来的安全风险。有了这些优势，可以预期这种新颖的思路在安全性要求较高的物联网场景中会有更多的发展。与传统的物联网网络相比，该架构采用可信计算技术构建安全基础，使物联网网络可以自动管理安全。此外，去中心化的架构可以降低物联网网络中单个节点被攻陷所带来的安全风险。有了这些优势，可以预期这种新颖的思路在安全性要求较高的物联网场景中会有更多的发展。与传统的物联网网络相比，该架构采用可信计算技术构建安全基础，使物联网网络可以自动管理安全。此外，去中心化架构可以降低物联网网络中单个节点被攻陷所带来的安全风险。有了这些优势，可以预期这种新颖的思路在安全性要求较高的物联网场景中会有更多的发展。
