The latest hardware encryption principle
With the development of decryption technology, MCU dongle is gradually eliminated by the market because of its simple algorithm, small storage space and easy to be copied by hardware. The domestic dongle manufacturers led by Beijing deep thinking Locke Software Technology Co., Ltd. have developed the fourth generation of dongle with better stability, larger storage space (up to 64K) and effective prevention of hard cloning - "smart card" dongle. "Smart card" dongle has been used by large domestic commercial software developers such as Qingzhou Guangda Kingdee, UFIDA, CAXA, Guanglianda, Shenji miaozao, Luban.
Taking the world's first smart card encryption lock - Jingrui IV as an example, this paper briefly introduces the principle of "code transplantation".
The encryption principle of "code migration" is a new and reliable software protection model. Its working principle is that some codes in the software are compiled and "transplanted" into the encryption lock hardware, and there is no copy of this code in the software.
In this software protection scheme, the key codes and data of PC application software "disappear" and are safely transplanted to the hardware of elite type IV encryption lock for protection. When needed, the application software can instruct the elite IV to run the key codes and data in the hardware and return the results through the function call engine, so that all the functions of the whole software can still be completed. Because there is no copy of these codes and data on the PC side, the decryptor has no way to guess the algorithm or steal the data, which greatly ensures the security of the whole software system. In short, elite IV provides a set of trusted solutions to theoretically ensure the security of software encryption. 1. Qingzhou Guangda engineering pricing software
