檢視 @SECURE PARAMETER 的原始碼

*Determine the rigor of privacy amplification. When QBER<0.2, the '''safe_factor''' use the first value, otherwise use the second value.
:safe_factor = s ; I(Eve_shannon_info) <= 2^(-s)ln(2)
*Is store as '''secure_parameter''' in the fortran code.

example
 @SECURE_PARAMETER
 30, 50

Which mean when [[@AUTO_PALENGTH]] is .true., the system will calculate key reduction rate with safe_factor=30 (if QBER<0.2) safe_factor=50 (if QBER>0.2).
