Abstract
An anti-counterfeiting electronic device includes a function component assigned with an identification code ID and a processor. The processor generates a random code K1 and transmits the random code K1 to the function component; the function component encrypts the random code K1 and the identification code ID to generate a key ID1. The processor further obtains the key ID1 from the function component and decrypts the key ID1 to generate an identification code ID2, and determines whether the identification code ID2 is the same as the ID and executes the system login command if the identification code ID2 is the same as the identification code ID. An anti-counterfeiting method is also provided.
