Internet of Things as an extension of the Internet, known as the third wave of the world's information industry. Experts predict that 2017 will be the first year of commercial networking. Internet of Things industry driven by the government to market-oriented, a large number of emerging Internet of Things technology applications will come into our lives. With the expansion of the Internet of Things industry, IoT security issues have become increasingly prominent, becoming an important factor restricting the large-scale application of Internet of Things.
At present, some enterprises at home and abroad have realized the important role of security in the development of the Internet of Things. They have also conducted research on security technologies and products for various levels of the Internet of Things. Next, we will take inventory of the major IoT security companies and technologies at home and abroad from the perception layer, transport layer, application layer and overall solution of the Internet of Things.
Perception-level security: ARM and Symantec have their own way
The perception layer is likened to the "skin and facial features" of the Internet of Things to identify objects and gather information. Although the perception layer is located at the bottom of the three-tier structure of the Internet of Things, it is the core of the Internet of Things system. The most common form of the perception layer of IoT is terminal equipment. Currently, many Internet of Things terminal devices have very low security capabilities and can easily become "helpers" for hacker attacks. For example, in October 2016, a massive "disconnection" network attack in the United States was caused by a hacker who launched a denial of service attack by infringing on a large number of IoT devices such as cameras. Therefore, it is extremely important that the perceptual layer have lightweight security technologies .
Currently, ARM and Symantec are more powerful in this regard. It is reported that ARM recently introduced two low-cost 32-bit ARM Cortex-M23 and Cortex-M33 chips based on the ARMv8-M architecture, which will be market-recognized security technology to the most demanding IoT endpoint; In addition, Symantec intends to secure IoT devices by embedding a root certificate based on a semi-lightweight EC password into the IoT endpoint through a globally unique identifier and authentication technology for IoT end devices.
Transport Layer Security: LPWAN industry is growing rapidly
Transport layer is mainly responsible for data transmission and processing, and its security functions are generally deployed with the transport network infrastructure. Due to the flexibility of IoT devices, the network transport layer must have a network with long-distance transmission capability. The common Internet cable connection is not flexible enough, the high power consumption of mobile communication network and the number of users also make it unsuitable for the Internet of Things system. Therefore, a new network transport layer is needed for IoT service.
Judging from the market development in recent years, LPWAN has been favored by the market as a private network designed for IoT applications. Sigfox and Lora continue to lead the market in this area and are already deployed in several countries. Of course, low-power wide area network (LPWAN) emerging as a matter of security must be subject to industry questioned, it is understood, Sigfox and Lora companies have invested enormous financial and energy security, in particular, Lora to do in the form of an ecosystem of security Protection, promote their network security deployment. In China, Huawei uses different forms to promote the construction of network infrastructure. Its main purpose is to promote NB-IOT technology through 3GPP international organizations by cooperating with a number of large international enterprises. They can use the core infrastructure of mobile communications (such as base stations) and make them serve the Internet of Things data transmission service with a small modification and upgrading. Although the NB-IOT standard was released in June this year, the actual deployment and application of the NB-IOT network has been slow so far due to a number of regulatory and licensing restrictions.
Application layer security: a hundred schools of thought
The application layer is the top layer in the three-layer structure of the Internet of Things. It mainly performs calculation, processing and knowledge mining on the acquisition data of the perception layer so as to realize real-time control, precise management and scientific decision-making of the physical world. IoT processing application layer is mainly cloud computing platform and its services, including big data processing. So IoT processing application layer security is to deal with the security of the platform itself and the services it provides. In this regard, almost every IoT processing platform has its own characteristics.
IoT security overall solution: Kuang network in the country dominate
The Internet of Things is a complex and diverse system of large-scale systems that require systematic solutions in terms of security and protection. At present, many international security companies claim to provide their own services in this area. For example, Symantec claims to provide IoT security overall solution and also released some research reports; Amazon AWS-IoT solution cloud platform as a total solution for the Internet of Things, Intel's Wind River also provides IoT security solutions.
However, there are not many domestic enterprises that provide overall security solutions for the Internet of Things. In this regard, Kuhn network is at the forefront of technological innovation. It is understood that Kuang En network assembled a group of top talents in the field of information security and coffee, with its industry-leading security technology as the basis for the perception of IoT security, developed IoT security gateway, which can effectively solve the perception layer Security issues; for the transport layer security of the Internet of Things, developed a security switch to enhance the security of the network transport layer; for processing application layer, developed a large industrial data situation awareness platform. These products cooperate with each other to provide security services for the entire industrial chain of industrial IoT systems as a whole and gradually apply their solutions to other IoT industries.
In this serie, all the truck rear door locks are with security keys. The material is galvanized steel. With the security keys, it can keep the goods inside the trucks much safer. We have two kind keys, one is standard key, which one key only belongs to one door lock. The other is one same key can open many door locks.
