Chip reverse can not find work. According to the relevant public information, chip reverse engineering is an advanced technology that requires relevant theoretical knowledge and practical experience, so it requires certain professional skills and capabilities. If you do not have the relevant professional skills and experience, it is difficult to find a needleWork on chip reverse engineering. DARPA has unveiled two high-profile project teams that will join forces to develop a new ARM-based security chip equipped with a powerful "security engine" designed to defend against chip attacks and supply chain threats such as reverse engineering.
Recent article[1] gives a good description of how reverse engineering might be performed in a moderately well equipped academic microelectronics laboratory (there are three of these in the UK, and perhaps two hundred academic or industrial facilities worldwide that might perform such work). usThe start will be by summarizing it and giving some background.
1, the original chip decryption data line has a variety of uses. First, the original chip decryption data line can be used to study and analyze the internal structure and function of the original chip. By decrypting the data line, we can gain an in-depth understanding of the working principle and design concept of the original chip. First, for some customers, chip Decryption provides custom chip design and manufacturing services, which opens up new application areas and business opportunities for customers. secondlyThe technology and method of chip decryption can be applied in maintenance and after-sales service, so that customers can better understand and master the use of the chip.
3, this kind of chip industry can achieve the purpose of preventing the reproduction of electronic products. With the help of special equipment or homemade equipment, using the vulnerabilities or software defects on the design of the single-chip microcomputer chip, through a variety of technical means, you can extract key information from the chip and obtain the program in the single-chip microcomputer, which is called single-chip decryption.
1. Probe techniqueThe technology is to directly expose the internal connection of the chip, and then observe, manipulate, interfere with the MCU to achieve the purpose of attack. The first step in an invasive attack is to unpack the chip (referred to as "opening" sometimes called "opening", English "DECAP", decapsulation).
2, the first method needs to bind the chip to the test fixture, with the help of the binding table to operate. In addition to the knowledge and necessary skills of the attacker, the second method also requires personal wisdom and patience, but it is relatively convenient to operate, completely homeMedium operation.
3, single-chip decryption is a very loaded thing, first of all, you need to oxidize the packaging surface of the chip, with professional equipment for decryption. The first is to dissolve the chip package completely, exposing the metal wiring. The chip needs to be attached to the test fixture and operated with the help of a binding table. The second is to remove only the plastic packaging on top of the silicon core.
