Access Control Security Becomes Focus on Vendors

In recent years, the scale of China's security products market has continued to expand and rapid growth, of which, access control products have emerged the expansion of the development. The integration of access control system and video surveillance system has become a hot spot for many access control manufacturers. In the development of technology, the security of access control systems has become a hot topic. This article simply lists the access control security technologies and discusses the importance of access control systems in the application of security technology.

Internet of Things technology emerges

After the 2010 Internet of Things was formally included in the national development strategy, in 2011, the state increased its support for the next generation of information technology such as the Internet of Things. New technologies such as the Internet of things and cloud computing were applied to building automation, security, and intelligence in succession. Home and other fields have become the most popular keywords in the intelligent construction industry. Many companies use the opportunity of the country to vigorously develop the Internet of Things and introduce this technology into the access control system to upgrade the access control technology.

The access control and lift protection supervision information platform construction system is just a typical example of the application of the Internet of Things in access control systems. Industry experts believe that with the continuous advancement of technology, Internet of Things, cloud computing and other technologies will be combined with access control technology more and more closely to better protect the safety of users.

Widely used NFC technology

With the increasing mobility of users, NFC technology is being widely used in multiple fields including mobile payment and transaction, transportation payment, customer loyalty program, and network information access. More and more mobile device manufacturers such as Nokia, Samsung (Google), Research in Motion (RIM), LG and ZTE are launching NFC-enabled mobile phones one after another. This will further promote the application and development of NFC technology in mobile access control.

At present, the application of NFC technology at home and abroad is still to be developed. To make the technology popular, it must pass the extensive cooperation of the industry. HIDGlobal has actively cooperated with NFC device manufacturers, such as the joint launch of NFC-enabled contactless smart card reader platform with Sony of Japan, specifically for notebook computers and mobile devices, and stores keys through the security components of the platform. Protects the reliability and integrity of identity information storage by embedding access control functions and Near Field Communication (NFC) capabilities into laptops and other mobile devices, enabling mobile device-based access control, computer security login, and travel expenses Payments, point-of-sale fees, and loyalty programs.

Bluetooth technology is safe and reliable

With the advent of the information society, the continuous development of science and technology, and the improvement of people's awareness of safety precautions, the use of access control systems in modern offices and people's daily lives has become more widespread. Bluetooth technology has also been successfully applied to access control systems. The transmission distance of devices using Bluetooth technology is not very long. In order to solve such problems, it is often equipped with certain relay devices during actual use. In this case, the entire connection can effectively achieve interoperability and improve the reliability of the system. In addition, the use of repeaters can provide a good opportunity for future product upgrades. By adopting Bluetooth technology, the installation cost of products will be significantly reduced, mainly in terms of labor costs and resource costs. The reduction in costs can also in turn promote the sales of products, which in turn will reduce other related costs.

In the access control industry, the vast majority of systems use RS-232 and RS-485 hardware interface standards to connect various readers and monitoring devices to each other. If the facilities that need to be monitored are not equipped with the necessary lines in advance, we have to create holes in the buildings so that suitable monitoring equipment can be installed. Now that we have Bluetooth technology, we can avoid this phenomenon. Not only that, Bluetooth technology also provides us with more secure communications security. Access control devices using Bluetooth technology can be used in many areas. Here are some examples of these: Gating areas: As mentioned above, products using Bluetooth technology can greatly ease the wiring work in smart card systems, making the replacement of products become very easy.

As an emerging technology, compared with other similar technologies, Bluetooth technology considers many factors in the design process, and has the following main features: high operating frequency, strong anti-interference, easy use, voice support, and no need for base stations. ; Small size, low power consumption; can be multi-way multi-directional link; strong confidentiality.

Access control encryption technology or the main trend

The use of home-grown algorithms for access control encryption technology will be the main trend for future development. Access security needs to be resolved from three aspects: application security, device security, and algorithm security. Application security mainly refers to the design of the key management system. The key system is the basis for the entire system to operate safely. The key task of the key management system is to generate, issue, and update the key, which is directly related to the security of the entire system. Customers use this software to generate and manage all types of application keys, complete the initialization of the cards themselves, and ensure that the customers have the initiative in key management and card issuance. Device security mainly refers to the access control card reader, which requires the built-in PSAM card slot and the SAM module in the access card reader. The PSAM card or SAM authentication module is used to store various types of keys, and passes the internal/external authentication method to the transaction. The mutual authentication of the card and terminal equipment ensures the legality of the transaction medium, which can greatly improve the security level of the access control system. The algorithm security is based on the domestic algorithm assigned by the National Cryptography Administration and approved by the State Cryptography Administration.

There are also views in the industry that access control encryption technology is likely to take a customizable algorithm and two-way decryption technology. As far as the current market is concerned, access control, as a specific application of RFID, will be more in combination with other security measures to solve application security problems in the application of security. For example, combined with video surveillance image comparison, multiple recognition modes combined with biometrics, dynamic password protection, etc., will be an important guarantee for the application of access control in high security areas.

Enlightenment from access control security crisis

At present, the gap between access control systems at home and abroad has been getting smaller and smaller. The advantages of foreign manufacturers' products lie in brands, popularity, and other aspects. The advantages of domestic manufacturers are flexible customization of functions and changes in pricing. If domestic manufacturers want to stand out from the competition, they cannot rely on price wars alone. Instead, they must increase R&D investment in hardware and software, and quickly make changes according to the individual features of different users to meet the needs of users; while the foreign brands do not have access to functions. Modifications, even if modified, have long periods and are expensive.

Domestic access companies can use the opportunity to resolve the issue of M1 card security vulnerabilities, give full play to the leading and directing role of technology support, strengthen the construction of information security support technology system and integrated application technology system, carry out integrated innovation, and enhance the basic security capabilities of information security. Through the development and application of key technologies, the use of domestic products with independent intellectual property rights and safe and controllable is promoted.

At the same time, we must also admit that the current electronic access control domestic products do have a big gap with foreign giants in high-end applications. However, China has its own characteristics in China. We have occupied an international leading position in the application of single cards. China is a market with strong assimilation capabilities. Access control companies must position their products according to their own markets, and based on domestic ones, they must unswervingly follow the one-card approach. If one looks at the world, they must follow the access control of foreign giants.
