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
