In terms of the characteristics of the smart home itself, in addition to the security of the network layer, there are many special security issues besides the network layer. In addition to relying on the security mechanism of the network layer, the usual smart devices will have more security protection mechanisms.
Security under new skills
Smart homes are not the same as mobile phones and computers. Users will not continue to operate the system. Many devices are even deployed in unsupervised scenes, especially with the gradual sophistication of big data usage, smart home resolution plans for smart homes. Can replace people to complete some operations.
Although in this case the device itself is not so simple to be free to install the virus software, but because no user is looking after it every day, the invaders can suggest some information tampering, the security of the device itself is simply broken, and it is very Simply found.
Smart home products touch the development of hardware, software and cloud channels, but subject to the lack of a good skills development team in most companies, and a well-established professional operation and maintenance team, the company usually chooses to rely on existing engineers to develop products independently. There may be some security risks in commodities, and the invaders use security loopholes that are not considered by various factors. Some professional skills can be used to monitor or receive the operation of such devices, steal user information, and even Infecting malicious programs, etc., brings confusion and loss to consumers and manufacturers.
Six smart home security issues
Regarding the security issues of smart homes, different professional companies with different security arrangements have different requirements. There are six aspects to think about: network security. That is, the security of the cloud pipeline on the local network and data, such as Cisco, Huawei hardware manufacturers compare the network security; security certification.
According to the risk assessment of the commodity and operating environment, the identity and authority of the user and the device are handled. This is a comparison of Internet companies like Yunmin Cloud; data encryption algorithm.
The smart home needs to do data encryption algorithms together with the cloud and the cloud. It can integrate the common algorithm and encryption and decryption mechanism according to the level of security requirements of the goods, and integrate it reasonably on the device side and the cloud KI public key infrastructure.
It has not been widely used in smart homes. How to identify the sender identity of the sensor and the reliability of data in the network transmission will be the issues that need to be considered in the next phase of the Internet of Things; the analysis of the continued security data.
This can be very demanding on big data, and can be analyzed through data analysis to prevent unsuccessful intrusions; the security maintenance of cloud interfaces.
The cloud is more secure than the local area network
In the meantime, the cloud is very important for smart home products. Most of the hardware itself is affected by factors such as cost and volume. The skills and talents in accounting and storage are limited. The intelligence is more complicated to carry the hardware itself. The algorithms, richer features, and intelligent resolution plans can be done with cloud channels, and the results are transferred to the hardware, making the hardware smarter and more responsive, while the hardware itself only needs to write the underlying transaction logic.
Another reason why the cloud is very important is that most device authorization, binding, data storage, computing, and resolution plans are handled by the cloud channel. LAN data transmission and WAN data transmission coexist. In the local area network, the device is connected to a gateway (router) to complete a small range of network communication, and the WAN transmission is connected to the World Wide Web via a light cat, and can access an external server. In the smart home scenario, the device is primarily connected to the router, then to the Internet, to the cloud channel, and then to the user's mobile phone.
The security problem of smart home, security layout is a general situation. It should be bundled together, communicate and cooperate with each other, promote each other, and then create a complete smart home security system.
