#124642 - RFID Door access control Responding to: ???'s previous message |
You are wasting your time if you want to try to reverse engineer this thing or interface with it because if its any good the protocol will be a challenge/response authentication type using strong encryption of nonces to verify that the device making the door open request is what it says it is and it will have replay attack protection, I would be very surprised if you are able to find any information as to the exact protocol used, and I would be amazed if you were able to crack it.
By the way nonces are words of psuedo random numbers,nonsense words or numbers used once or UK Prison slang for a sex offenders take your choice. |
