Hardware encryption chip embedded with program code using smart card technology

At present, more and more Chinese companies are beginning to recognize the importance of enterprise informatization in order to maintain their competitive position in the fierce competition, and hope to make full use of their IT investment to save the total cost of ownership (TCO). At the same time, with the enhancement of corporate competition awareness, how to do a good job of confidentiality while doing information construction is becoming a problem faced by various enterprises.

Lingke Xinan Company is the first company in China to introduce smart card technology into the encryption chip industry. It fully utilizes the high security of the smart card chip itself, and is supplemented by LKCOS, the chip operating system of Lingke Core's independent copyright, to ensure the security of the underlying interface of the chip. The program inside the protection chip from the inside out is not pirated.

The LKT4100 anti-piracy chip developed by the company has attracted much attention from the market and has become a hot spot for various manufacturers.

Lingke Core's LKT4100 anti-piracy chip truly provides comprehensive and high-security protection for users' software code and important data. The encryption principle is a new and credible software protection model. Working principle: In this encryption protection scheme, the key code and data of the internal application software of the MCU are safely transplanted to the hardware of the LKT4100 anti-piracy chip. stand up. When needed, the application software can call the engine code to run the key code and data in the hardware and return the result, so that the entire function of the entire software can still be completed. Since these codes and data have no copy on the MCU side, the decryptor has no way to guess the algorithm or steal data, thus greatly ensuring the security of the entire software system.

With the increasing performance of embedded products, embedded systems are rapidly spreading in the consumer electronics, automotive, industrial control and communications industries; however, due to the high development cost of embedded systems and long development cycles, key technologies are encrypted and important data. The issue of confidentiality has become increasingly prominent. Only by mastering intellectual property rights through independent innovation can we occupy the forefront of information technology. In these embedded systems, using low-cost, high-efficiency methods to protect their research results from illegal imitation and plagiarism, while preserving some key code or data has become one of the problems that plague R&D engineers.

The LKT4100 series anti-piracy chip is the first hardware encryption chip in the global hardware copyright protection field that uses smart card technology to embed program code. Since the introduction of the hardware copyright protection industry by the LKT4100 series of encryption chips, more than a thousand hardware development and solution development providers have adopted this advanced technology, and the cumulative sales have exceeded 10 million.

The working principle is that software and hardware developers can download some of the algorithms and code in their own software to the chip to run. The user writes the operation code in standard C language. Compile and download to the smart chip. During the actual running of the software, the program segment in the smart chip is run by calling the function mode, and the running result is obtained, and the result is used as input data for further running by the user program. The LKT4100 series of anti-theft chips became part of the software product. Fundamentally, the possibility of the program being cracked is eliminated. LKT4100 series anti-piracy chip can effectively protect the intellectual property of its own software, safeguard its own economic interests, and effectively avoid software piracy.

As the first high-tech enterprise in China to introduce smart card technology into the encryption chip industry, Lingke Xinan has developed LKT4100 series anti-piracy chip through technological innovation and research and development. It has become a tool for information manufacturers to protect their legitimate rights and interests, and has gradually developed LKT4101. LKT4200 (32-bit smart card chip platform high-end encryption chip), LKT4300 (32-bit smart card chip platform multi-interface encryption chip) and other serial encryption products, opened up a new world for China's embedded encryption chip market.

Paper and cardboard packaging is limited by the weight .There are also issues with its performance in extreme weather conditions, as it is likely to suffer damage in humid, wet or very cold conditions. It is however very cheap and easily recyclable.

Whether you are sending out bottles by mail-order, selling your cans in a gift pack or transit packaging them to dispatch to a wholesaler, we can offer a variety of packaging solutions (including bespoke packaging design) to promote and protect  your product.
