在稳增长与碳减排双重压力下,识别用能权交易制度对城市低碳转型发展的影响具有重要的理论和实践意义。基于2006—2021年中国282个地级及以上城市面板数据,利用超效率SBM模型测度碳排放效率,使用双重差分模型考察用能权交易制度对碳排放效率的影响效应、内在机制及异质性表现,并对其空间溢出效应、政策协同效应和环境红利进行探析。结果表明:2006—2021年,中国城市碳排放效率总体呈现波动上升态势,用能权交易制度可以显著提升碳排放效率,且这一结论经过稳健性检验后依然成立。用能权交易制度通过绿色技术创新、产业结构升级提升了城市碳排放效率,用能权交易制度的碳排放效率提升效应在东部城市、大规模城市和资源型城市中表现得较为明显。用能权交易制度对城市碳排放效率的影响具有正向空间溢出效应,且碳规制双试点政策对城市碳排放效率的提升效应较为明显。因此,用能权交易制度能够发挥减污降碳协同治理效应。研究结论可为稳步推广用能权交易制度与促进城市低碳转型发展提供一定的政策启示。

目前已有文献给出了uBlock分组密码算法的侧信道防护方案,但是这些方案不仅延迟较高,难以适用于低延迟高吞吐场景,而且在毛刺探测模型下缺乏可证明安全性.针对这一问题,本文给出了在毛刺探测模型下具有可证明安全性的uBlock算法的低延迟门限实现方案.此外,我们引入了Changing of the Guards技术来避免防护方案在执行过程中需要额外随机数.对于防护方案的安全性,我们用自动化评估工具SILVER验证了S盒的毛刺探测安全性,并用泄露评估技术TVLA(Test Vector Leakage Assessment)验证了防护方案的整个电路的安全性.最后,我们用Design Compiler工具对防护方案的性能消耗情况进行了评估.评估结果显示,与序列化实现方式的uBlock防护方案相比,我们的防护方案的延迟能够减少约95%.
