BCC (Block Check Character) Knowledge
BCC (Block Check Character), also known as XOR Checksum, is a data verification method that performs XOR operations on all bytes in a data stream. BCC and XOR Checksum are essentially the same algorithm with different names.
Features
- Simple calculation: Only requires XOR operation
- Also known as XOR Checksum or Longitudinal Parity Check
- Good real-time performance: Can calculate while receiving data
- Low resource usage: Only needs one byte of storage
- Widely used in industrial communication protocols
Applications
- Industrial communication protocols (e.g., Modbus)
- Serial communication
- Data packet verification
- Simple error detection
- Embedded systems communication
Security Recommendations
- Not suitable for data security purposes
- Cannot detect even number of bit errors
- Consider using CRC for better error detection
- Combine with other verification methods for critical data
