Experts point out that PCB copy board before derivative, has experienced a long journey "core" road. Without this important chip electronic components, circuit board without this support. In the same way, there is no chip decryption, cannot be fully for PCB copy board. Decryption, as it were, is the most important step to PCB copy board, will determine the quality of electronic products.
So, how to do the chip decryption?
Single chip microcomputer (MCU) general block have internal EEPROM/FLASH for users to store procedures and work data. In order to prevent unauthorized access to or copies of single chip machine program, with most of the single chip microcomputer can locate or encrypt bytes, in order to protect the on chip program. In order to read on chip program, microcontroller attacker with the aid of special equipment or homemade equipment, the use of loopholes in the design of the microcontroller chip or software defect, through a variety of technical means, can extract key information from chip, this process is called chip decryption.
Companies usually do decryption must have the international leading technology equipment, special algorithm parse software, and skilled professional r&d team. Single-chip decryption market in China and only a single chip microcomputer with such strength, not only in the decryption IC software fault attack, electronic detection attack, probe technology, produce technology and have rich practical experience, and has been focused on the function of encryption chip design research and the realization of algorithm and software algorithm, such as: des encryption, symmetric encryption and md5 encryption and decryption algorithm research, and the realization of the function of hardware, system software development and the design of the chip, the underlying driver of nested, such as in CPLD/DSP/PLD decryption has many classic case.
PCB copy board "core" is the best policy
Chip is the core of the electronic products, almost determines the function of the PCB board, thus affect the entire electronic product performance. So PCB copy board to be secondary development or hardware and software development can, from the perspective of the chip decryption link, add or delete procedures can be customized by IC reverse design function of chip, realize the function prototype of secondary development, the secondary development of prototype software, hardware function of secondary development, etc. Can also be based on chip technology principle, design, manufacture process, structure, mechanism and so on the deep insight into, make new breakthroughs, help the realization of the new chip design or product design scheme.
A dishonest way to obtain commercial secrets of the other businesses, is a common ACTS of unfair competition. 17, China's supreme people's court announced "application about the trial of civil cases of unfair competition law" the explanation of some issues, first make clear a regulation, through their own development or reverse engineering methods such as trade secrets, not as the anti-unfair competition law provisions of the commercial secret infringement.
