5/21/2023 0 Comments Autocrypt key ivBecause the encryption key never leaves the hardware, and without having the correct encryption key, the information cannot be decrypted. The encryption engine is the most powerful unit of the CRYPTO-BOX, take advantage of it. Some examples how to avoid that: Do not only expect fixed responses, instead use the encryption capabilities to generate dynamic responses from the CRYPTO-BOX. Recording the communication with the dongle and trying to emulate it (replay attack) This can be done by replacing either the functions library of the CRYPTO-BOX or the CRYPTO-BOX driver with a faked version which returns certain values at certain inquiries. Attempts to defeat software protection might comprise of these attacks 2.1. removing protection are based on the following approaches: 2. The Case Customers may ask: "Is there a way to remove the possibility to be emulated? We suspect that some of our end users have done it already." Websites offering such illegal 'services' exist since many years, but this is no proof that the CRYPTO-BOX was cracked in general! And it is even no proof that your particular application was or can be cracked by them. The Case Attempts to defeat software protection might comprise of these attacks Recording the communication with the dongle and trying to emulate it (replay attack) In case of AutoCrypt: Dumping the application Analyzing the source code and use debugging/disassembling techniques to remove the protection Seeing the challenge from the hacker's point of view, and what makes hacker's life difficult.4 How to deal with hackers, cracking or memory dumps 1.
