You've probably heard that by 2020, there would be over 50 billion IoT devices connected to the internet. But how many of these IoT applications are actually in use today? Despite the hype, many IoT applications haven't taken off yet due to lingering security concerns. To address this issue, a domestic startup called AstralNet has introduced the SAGE (Secure Authentication Group Engine) algorithm, aiming to serve as the key to unlocking the full potential of future IoT applications.
According to Chen Jixian, co-founder and CEO of AstralNet, scenarios like hacked self-driving cars, remote-controlled nuclear power plants, or even factory explosions—common in Hollywood movies—are not far-fetched anymore. With the rise of the Internet of Things, such threats could become real. Chi Mingyang, the company's technical director, added that because IoT devices can’t run traditional antivirus software, it’s crucial to prevent cyberattacks at the source.
The team’s two-way authentication mechanism isn’t a new IP but rather an integration of existing technologies. They’ve packaged well-known encryption algorithms, such as elliptic curve cryptography, along with a key management system into a software development kit (SDK), which is then embedded into hardware encryption ICs.
Chen explained that the company offers both pure software encryption solutions and hardware-embedded options. While software alone can’t guarantee 100% protection, for customers who demand maximum security, the software is embedded into encryption chips, making it nearly impossible for hackers to steal firmware secrets. Additionally, the SDK allows for customizable permutations and combinations of encryption algorithms based on specific customer needs.
For instance, in a smart home application, the encryption device might be a small electronic key. In such cases, overly complex algorithms aren’t necessary due to power constraints. A simple and efficient solution is more suitable to match user expectations and battery life.
The two-way authentication mechanism developed by AstralNet enables true end-to-end mutual authentication without relying on the cloud. Imagine how current ATM systems work: the cash machine acts like a computer, and the bank side has a corresponding server (or cloud). When you withdraw money, the front-end device connects to the cloud to get a certificate, and then the back-end verifies the transaction before proceeding.
With AstralNet’s technology, these cloud-based steps can be eliminated, allowing direct two-way authentication between devices. Chen added that this mechanism automatically generates keys within the system and uses network transmission to enable secure communication between devices.
Chi Mingyang believes that the real Internet of Things can only be realized if all devices operate independently of the cloud. He argues that it’s impractical for every device to rely on cloud-based authentication in the future. The company’s goal is to ensure secure, mutual authentication between devices without any external dependencies.
It’s worth noting that AstralNet’s SDK can be embedded into low-power Cortex M0 microcontrollers, and the two-way authentication process takes just 60 milliseconds. This makes their solution both efficient and scalable for a wide range of IoT applications.
FUNCTION DESCRIPTION
Countdown socket has an AC outlet, the maximum can output 230 V16A of power, there are two control modes, that is, countdown off and countdown on. It is convenient to control the equipment which needs to switch off or turn on AC. improve the safety of the use of some equipment and save more energy.
SET Timer
1,Countdown plug in the socket, all indicator lights red flash three times, at this time the socket has no output, for the normal state, into the countdown state. Click the button, the first red light up, the socket output after an hour off, and then short press the button can set the socket timing of 2 H.4H.6H.8H.10H.OFF.
2,Long press button 3s, all indicator lights green flash three times, at this time the socket has output, for the regular open state, into the countdown on state. Click on the button, the first green light on, the socket is closed an hour later, and then press the button to set the socket countdown 2 H.4H.6H.8H.10H.OFF.
3,Press button 3 longer S, all indicator lights red light flash 3 times again into countdown mode.
4,Select the required countdown time mode, the corresponding mode countdown lights up, start countdown until the end of the countdown time. The outlet that controls the output will start or stop the output.
5,After the countdown starts, the time indicator will change automatically from high to low until the countdown is over.
NOTE:
1,Check that the power connection is good.
2,Use only indoors and in dry places.
3,This product does not convert AC voltage.
4,Maximum load not exceeding 16A 3680W.
5,Grounding is required for safety.
6,Any questions, please contact the electrician.
