Key agreement protocols are essential for secure communications. In this paper, to solve the inherent key escrow problem of identity-based cryptography, an escrow-free certificate-based authenticated key agreement （CB-AK） protocol with perfect forward secrecy is proposed. Our protocol makes use of pairings on elliptic curves. The protocol is described and its properties are discussed though comparison with Smart＇s protocol.

The majority of existing escrowable identity-based key agreement protocols only provide partial forward secrecy. Such protocols are, arguably, not suitable for many real-word applications, as the latter tends to require a stronger sense of forward secrecy--perfect forward secrecy. In this paper, we propose an efficient perfect forward-secure identity-based key agreement protocol in the escrow mode. We prove the security of our protocol in the random oracle model, assuming the intractability of the Gap Bilinear Diffie-Hellman （GBDH） problem.

In the area of secure Web information system, mutual authentication and key agreement are essential between Web clients and servers. An efficient certificateless authenticated key agreement protocol for Web client/server setting is proposed, which uses pairings on certain elliptic curves. We show that the newly proposed key agreement protocol is practical and of great efficiency, meanwhile, it satisfies every desired security require ments for key agreement protocols.

目的探讨清热健脾法治疗Hp初治失败患者的临床疗效与安全性。方法回顾性分析2021年1月-2022年12月本院155例Hp初治失败患者的临床资料,根据治疗方案分为中药组66例和西药组89例。采用Python 3.70进行倾向性评分匹配(PSM),按1∶1比例均衡治疗前易混杂因素,最终2组各有66例配对成功。中药组予以一清胶囊+健脾丸,4周为1个疗程;西药组予四联抗Hp补救方案,2周为1个疗程。2组均治疗1个疗程。采用14 C呼气试验检测Hp并计算其清除率;从餐后饱胀不适、早饱感、中上腹痛、中上腹烧灼感4个方面进行功能性消化不良(FD)总体症状评分;观察治疗期间的不良反应,评价临床疗效。结果治疗后,中药组Hp清除率为75.76%(50/66)、西药组为83.33%(55/66),2组均较同组治疗前明显好转,但组间比较差异无统计学意义(χ^(2)=1.16,P=0.281)。中药组治疗后餐后饱胀不适[1(0,2)分比4(2,4)分,Z=-6.85]、早饱感[2(0,2)分比4(4,6)分,Z=-8.02]、中上腹痛[2(2,4)分比4(4,6)分,Z=-4.48]积分低于西药组(P<0.01)。中药组总有效率为75.76%(50/66)、西药组为69.70%(46/66),2组比较差异无统计学意义(χ^(2)=2.00,P=0.573)。2组治疗期间未发生不良反应。结论清热健脾法治疗Hp初治失败患者,其Hp清除率与临床总有效率与西药相当,可有效改善Hp初治失败患者的临床症状。

The certificateless authenticated key agreement protocol proposed by Mandt et al does not haVE the property of key-compromise impersonation （K-CI） resilience. An improved protocol with a simple modification of their protocol is proposed in this paper. In particular, our improved protocol is proved to be immune to the K-CI attack and at the same time possess other security properties.

Software Defined Network (SDN) makes network management more flexible by separating control plane and data plane, centralized control and being programmable. Although, network measurement still remains in primary stage in SDN, it has become an essential research field in SDN management. In this context, this paper presents a low-cost high-accuracy measurement framework to support various network measurement tasks, such as throughput, delay and packet loss rate. In this framework, we only measure per-flow edge switches (the first and the last switches). In addition, a new adaptive sampling algorithm is proposed to significantly improve measurement accuracy and decrease network overhead. Meanwhile, we consider a low-cost topology discovery approach into our framework instead of topology discovery currently implemented by SDN controller frameworks. In order to improve the accuracy of delay, we also join a time threshold value to adjust the time delay. Furthermore, we consider and analyze the balance between measurement overhead and accuracy in several aspects. Last, we utilize POX controller to implement the proposed measurement framework. The effectiveness of our solution is demonstrated through simulations in Mininet and Matlab.

天麻萌发菌和蜜环菌是在天麻种子萌发和生长时为其提供营养来源的共生菌和伴生菌,两者配比不同直接影响到天麻零代种的产量。本试验通过不同蒴果密度及萌发菌和蜜环菌配比,探究对零代种的产量、零代种分级产量占比的影响,结果表明萌发菌与蜜环菌配比比例为1∶3,且天麻蒴果用量为18~24个/m^(2)时,天麻零代种产量最高。
