After Prism event, off "IOE" became a popular slogan of the domestic IT industry. Therefore, the network equipment for PCB copy board and localization has become a trend. As foreign high technology high threshold to achieve localization of independent innovation is not so easy, but PCB copy board through reverse analysis of the original product, can quickly grasp the product PCB files, Bom list, schematics and other full technical information, thus breaking technical barriers, digestion and absorption as a basis for further development of domestic production. PCB copy board needs to include some on-board chip decryption .But an industry this there is another concern, he said only PCB copy board is not enough, "PCB copy board domestic server products, is still used in Intel's chips, the server is still foreign chip inside." So establish a comprehensive national information security mechanisms rely solely on a single PCB copy board is difficult to achieve, you must also include a circuit board chip decryption, we can not rely only on external chip purchases. Although China has the chip manufacturing country, but still awkward at the lowest end of the industrial chain, only engaged in OEM business, have failed to grasp the core technology, 80% to 90% of the chip is still monopolized international manufacturers, even at the high end uncompetitive. The main reason is lack of funding research and development of China's chip, a longer period, it is difficult to see short-term benefits, allowing companies to reduce the enthusiasm for chip development. The chip decryption only a small investment, quick, and can be carried out on the basis of the original chip reverse engineer, leak filled and functional modifications, so that the new chip technology upgraded with superior functionality, the encryption will be able to ensure the country again information security.
