This process allows you to analyze and replay the key fob’s signal for unauthorized access.

1. Set Up the Flow Graph: Open GNURadio Companion and create a new flow graph.
2. Add Options Block: Set the ID to “top_block” and the Generate Options to “QT GUI” for a graphical interface.
3. Add Osmocom Source Block:
   • This block communicates with the HackRF device.
   • Set the sample rate (e.g., 2M Hz).
   • Specify the channel frequency of the car key (e.g., 433.9M Hz).
   • Set RF Gains to 0 to avoid errors during the demo.
4. Add QT GUI Waterfall Sink Block:
   • This block displays the captured frequencies graphically.
   • Set the Center Frequency to 0 by default.
   • Set the Bandwidth to match the sample rate (e.g., 2M Hz).
5. Connect the Blocks: Connect the Osmocom Source block to the QT GUI Waterfall Sink block.
6. Run the Flow Graph: Execute the flow graph to start capturing frequencies.
7. Capture the Key Frequency: Press the button on the car key fob to emit the frequency. Observe the peak on the QT GUI Waterfall Sink, which denotes the captured frequency.

How do rolling codes enhance the security of keyless entry systems? Rolling codes enhance the security of keyless entry systems by generating a new, unpredictable code for each use, preventing attackers from replaying captured signals to gain unauthorized access. This method ensures that each transmission is unique and valid only once.

4.1.1 How Rolling Codes Work

Rolling codes, also known as hopping codes, are a mechanism used in keyless smart cars to prevent replay and relay attacks. The system works by generating a new, unpredictable code for each use.

3. Code Comparison: The receiver compares the received code to its calculated next number code.
4. Tolerance for Missed Codes: A typical implementation compares within the next 256 codes in case the receiver missed some transmitted keys.

4.2 KeeLoq Encryption

What role does KeeLoq encryption play in securing keyless entry systems? KeeLoq encryption secures keyless entry systems by encrypting the data transmitted between the key fob and the vehicle, making it difficult for attackers to intercept and replicate the signal. This encryption method adds a layer of security against replay and relay attacks.

4.2.1 Understanding KeeLoq Encryption

KeeLoq is a proprietary block cipher used in keyless entry systems to encrypt the communication between the key fob and the vehicle.

1. Encryption Process: KeeLoq encoders encrypt a 0-filled 32-bit block with the KeeLoq cipher to produce a 32-bit “hopping code.”
2. Initialization Vector: A 32-bit initialization vector is linearly added (XORed) to the 32 least significant bits of the key prior to encryption and after decryption.
3. Counter Mechanism: The Counter shields the frequency numeric code from being captured. When the encoder detects the press of a button, it reads the input and increments the Sync Counter value.
4. Random Code Generation: The counter and keys are input to the encryption algorithm, and the output is a 32-bit data that changes with every press of the button, making the code randomly hopping and generated.
5. Data Combination: This 32-bit code is combined with a fixed 34-bit portion containing information about the serial number from which the code is transmitted to the receiver.
