  • Decide after the privacy amplification process, the key reduction amount is calculated by the system or decided by the user.
Note:If calculated by the system, the formula is:
paKeyLength_tmp = @ECKEY LEN BLOCK - eve_info_estimate - safe_factor
[safe_factor:Determined by @SECURE PARAMETER]
[eve_info_estimate = @ECKEY LEN BLOCK*binary_entropy_function(QBER)]
[binary_entropy_function(x):y=-x*log2(x)-(1-x)*log2(1-x)]
  • Is store as autoPaLength in the fortran code.

example

@AUTO_PALENGTH
.TRUE.

Which mean the key reduction amount will calculated by the system like the formula above.
