Post – For (BAS), that is really an important thing that needs to be talked about. Let's first talk about this Post – what it is. In fact, this is cryptography technology in the post-quantum era! You have to listen to why it is called the post-quantum era – it means that once quantum computers become super powerful and practical, many popular encryption methods will become less secure and unreliable. This Post-, that is, the cryptographic technology introduced to deal with future quantum threats and ensure the security of information and data.
Let’s break it down and explain why it is important to BAS. BAS, as we all know, is responsible for various automation tasks in buildings – such as adjusting temperature, controlling lighting, and supervising security systems. The data transmitted and stored here are all related to the normal operation of the building and the safety of the people inside.
On the one hand , once quantum computers rise, what harm will it do to traditional encryption? These traditional encryption algorithms rely on the computational difficulties of number theory, such as the RSA algorithm and elliptic curve cryptography, which require a lot of time to solve specific problems mathematically to find the answer. But quantum computers are powerful in using quantum theory principles, which can exponentially increase computing speed. Once quantum computers reach practical standards, the above algorithms may be quickly cracked. So in BAS, bad guys can easily intercept the control signals in transmission, or tamper with various adjustment building equipment setting instructions, etc., and ultimately destroy the normal operation of the building.
On the other hand , how effective are the advantages of Post – in ensuring BAS security. First of all, post-quantum cryptographic algorithms are basically based on more complex mathematical difficulties. For example, lattice-based cryptography, coding-based cryptography, and Hash-based digital signatures are basically the operation structure and core principles to avoid being effectively cracked by quantum computers in common ways. This can ensure that the instructions in the BAS are transmitted without error and data privacy can be guaranteed.
Now that I understand its importance. Then we will continue to talk in detail through Q&A.
Question 1: How is Post – applied and integrated into the specific BAS process?
In fact, the first step is to make a selection of system components and select compatible products. Then we choose those devices and sensors that come with post-quantum algorithm functions and install them… In addition, the operating system must be updated; then it is necessary to reset the network and cloud connection protocols, ensure security keys and passwords… In terms of communication, encryption is also done to ensure that all exchanged data can be safely protected from interference and destruction.
Question 2: What is the approximate cost budget for applying a Post-BAS?
The application of BAS Post- will involve a certain cost. Adding and updating new equipment is the first part. It is difficult to say whether the price meets the standard, and the price is different. If the hardware equipment is older and needs to be completely replaced, the cost will be even higher! Moreover, the software licensing, updating and computing processes also cost money – additional hardware resources must ensure operating efficiency without affecting BAS computing capabilities and operation. Provide global procurement services for weak current intelligent products!
Question 3: Will it have a big change or bad impact on the original performance of BAS? How to control
After using the new encryption program, the computational load is very large, which may affect the BAS response time and result in a slightly slower speed. Therefore, it is very important for us to take some optimization measures to control this consequence, eh! Upgrading the core components can reduce the delay to ensure that the key processing is fast enough, adopt a distributed structure, and reduce the computing pressure in each partition. In addition, the code itself has parallelism on the system and can design multiple processes to reduce the running delay! It can perfectly solve the problem and ensure that the original performance rarely changes.
It is necessary to talk about post-quantum cryptography. We should take appropriate and effective steps as much as possible to integrate it into the BAS system in advance to ensure that BAS can still provide safe, stable, reliable and good services to building users as we get closer and closer to the quantum era in the future! Absolutely don’t be slow to follow this global industry trend! You should plan ahead and take a proactive approach. Let safety always be ahead of threats and risks… This can better protect the smart buildings we build and build, which is stable!
