Numerical Security Framework for QKD with Bypass Channels

A numerical SDP-based framework for QKD key rates under physically restricted eavesdropping confirms SP-BB84 gains no benefit from bypass constraints, but finds improvements with detector efficiency mismatch and weak coherent pulse protocols in satellite QKD.
