China's LED lighting industry has been supported by government policies and has grown rapidly in just a few years. LED companies have sprung up. The seemingly prosperous LED lighting industry is not as infinite as we imagined. In fact, there are huge hidden dangers behind it. At present, the domestic LED enterprises are small in scale, mostly in small and medium-sized enterprises. This year, 1/5 LED companies in China will face a bankruptcy crisis. Why is this?
Chinese LED companies now rely heavily on foreign chips, just as children rely on their parents, and more than half of their core technology is occupied by a few large foreign companies. The cost of chip introduction is high, and with the decline in the price of LED lights, small and medium-sized enterprises can only obtain meager profits, and it is extremely difficult to survive.
Domestic LED companies have long introduced foreign chips, so it is better to introduce chip technology directly. Chip decryption means that a single-chip attacker can use the special equipment or self-made equipment to exploit the loopholes or software defects in the design of the single-chip chip. Through various technical means, key information can be extracted from the chip and the program in the single-chip microcomputer can be obtained. Decryption technology is dedicated to the reverse research of high-tech chips, learning and mastering the essence of the technology. Direct introduction of chip technology can help reduce costs and reduce the economic burden of small and medium-sized enterprises.
In order to get rid of this embarrassing situation, Chinese LED companies must strengthen their independent research and development capabilities and master core technologies. Enterprises can strengthen the imitation and innovation by deciphering technology, digesting and absorbing foreign advanced technology, and improving their core technologies to achieve micro-innovation or comprehensive innovation and create their own core technologies. In the process of decryption, the original chip can be reverse engineered according to the requirements of the customer, and the existing problems of the original chip can be solved and improved, and a new chip can be designed. The SCM Decryption Studio has become the reverse research laboratory for IC and software decryption with the most professional strength and influence in China. 
Chip decryption technology or help the LED industry get rid of "dependency"
The times have continued to develop and develop, and various emerging industries have emerged. The emergence of every emerging industry must attract many investors, and the LED lighting industry is no exception. Although the LED lighting industry has not developed for a long time, it has been a boom in recent years. Many investors have entered the industry, and the industry has expanded. The future development of the LED lighting industry also requires the use of chip decryption technology.
