摘要：
后量子密码学（PQC）生成的负载对个人区域网络的定时和能量预算造成压力。在后量子密钥交换（PQKE）中，这导致严重的碎片化、延长的无线电活动和低功耗设备的高传输开销。先前的工作优化了加密计算，但大多忽略了通信成本。本文通过蓝牙低能耗作为代表平台，将计算和通信成本分开，并在真实硬件上验证了它们。结果表明，通信往往主导PQKE的能量消耗，超过加密成本。因此，高效的抗量子配对需要协调的协议配置和底层优化。本文为开发者提供了一种实际的方法来考虑PQC的能量权衡，并影响个人区域网络标准向量子安全操作的演变。
英文摘要：
Post-Quantum Cryptography (PQC) creates payloads that strain the timing and energy budgets of Personal Area Networks. In post-quantum key exchange (PQKE), this causes severe fragmentation, prolonged radio activity, and high transmission overhead on low-power devices. Prior work optimizes cryptographic computation but largely ignores communication cost. This paper separates computation and communication costs using Bluetooth Low Energy as a representative platform and validates them on real hardware. Results show communication often dominates PQKE energy, exceeding cryptographic cost. Efficient quantum-resilient pairing therefore requires coordinated protocol configuration and lower-layer optimization. This work provides developers a practical way to reason about PQC energy trade-offs and informs the evolution of PAN standards toward quantum-safe operation.
