You must have heard that by 2020, there will be more than 50 billion IoT devices connected to the Internet, but to this day, how many actual IoT applications have been used? At this stage, there are many Internet applications that have not yet taken off, because the security concerns have not been removed. To this end, the domestic startup AstralNet launched the SAGE (Secure Authenric TIon Group Engine) algorithm, hope to use this mechanism as the key to the future IoT application takeoff.
AstralNet co-founder and CEO Chen Jixian said that whether the connected vehicles are hacked, there are action bombs, or hackers remotely control nuclear power plants, and then detonate factory and other Hollywood movie scenes, after the rise of the concept of Internet of Things, there is May happen. AstralNet co-founder and technical director Chi Mingyang further explained that because IoT devices cannot install anti-virus software, it is necessary to prevent hackers and viruses from being solved from the source.
The team's two-way authentication mechanism algorithm is not a new IP, but the existing encryption algorithm, elliptic curve password, and key management system are packaged into a software development kit (SDK), and then the customer The software is then embedded in the hardware encryption IC.
Chen Jixian explained that the company can provide pure software encryption technology services, and can also be embedded in hardware; the reason is that software encryption technology can not achieve 100% intrusion prevention, if the customer wants to resist 100% hacking, The company will embed the software into the encryption chip for software and hardware integration, so that hackers can not steal firmware secrets; in addition, the encryption algorithms contained in the SDK can also provide different permutations and combinations according to different needs and applications of customers.
For example, in a smart home application, the encryption device may only be a small electronic key. This type of application does not need to carry too complicated encryption algorithms. Because it is too power-consuming, the battery life may not match. User needs.
The mechanism of AstralNet two-way authentication algorithm will achieve true end-to-end mutual authentication without having to go through the cloud. Imagine how the current ATM encryption calculus works. You can think of the cash machine as a computer, and there will be a corresponding host on the bank side, which is a server (cloud) connected at both ends; when the withdrawal is made, the front end computer is connected to the cloud to obtain the certificate. Then the back-end host then authenticates whether the front-end computer operator is the person and can confirm the correct transaction before starting the subsequent transaction.
After importing the company's technology, you can eliminate the steps in the cloud to achieve the ability to make two-way authentication between devices; Chen Jixian added that this mechanism allows the key to be automatically generated in the system, and then through the network transmission technology Make two-way authentication between devices.
Chi Mingyang believes that the real Internet of Things can only be achieved by exempting all devices from the cloud, because it is impossible for all devices to be connected to the cloud for authentication in the future. The company wants to achieve mutual authentication and security between devices. .
It is understood that the SDK provided by AstralNet can be embedded in the low-power Cortex M0, and the two-way authentication operation time only takes 60 milliseconds.
