- 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
- [I(Eve_shannon_info) <= 2^(-s)ln(2) ; s = safe_factor]
- [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.
