AI Technical Summary
Existing technologies are insufficient to effectively prevent the reverse engineering of controller chips, leading to the infringement of intellectual property rights by competitors and harming the interests of developers.
A controller program protection system is adopted. By adding a unique verification key to each product, and using a combination of OTP chip and encryption chip, the verification key is dynamically calculated and stored to ensure that the data transmission is encrypted, prevent waveform analysis, and achieve one-to-one matching use.
Effectively control product quantity, prevent reverse engineering, protect developers' intellectual property rights, ensure the number of legitimate products on the market, and prevent illegal counterfeiting.
