GF(3n)椭圆曲线密码体制中标量乘快速算法研究
Research on Fast Algorithms for Scalar Multiplication of Elliptic Curve Cryptography over GF (3n)
 [PDF]

Abstract: 本文研究了特征为3的椭圆曲线密码体制中标量乘的快速算法,并针对底层运算和上层运算分别进行改进。在底层运算中,采用递推归纳、乘法代替求逆、立方代替乘法的思想提出在仿射坐标下直接计算3kP的算法,将求逆运算降至1次;在上层运算中,采用滑动窗口标量乘的方法,既有效减少了非零窗口的长度又减少了算法中3倍点总的运算量。
In this paper we investigate the fast algorithm of scalar multiplication based on Elliptic Curve Cryptography (ECC) over fields of characteristic three, and make improvements both in underlying operations and upper operations respectively. In the underlying operations, we deduce a formula of calculating 3kP directly under the affine coordinates based upon the idea of recursion, trading inversion for multiplication and trading multiplication for cube, which reduces the inversion to once; in the upper operations, we adopt the sliding window scalar multiplication method, which reduces the length of the non-zero windows and the total computations of 3P effectively.





传感器技术在汽车上的应用

现代物理知识 , 2006,
Abstract: 不同用途的传感器装置在汽车的相关部位上,可有效监测车辆各个部位的工作状况。它们能够发现车辆的异常情况,以电信号方式向计算机报告,以便及时排除车辆故障,确保行车安全。目前传感器在汽车上的应用主要在以下几个方面。一、空气温度传感器(ACT)空气温度传感器(ACT)感测进入发动机进气歧管的空气温度。这种装置有一个热感电阻的触头,装置在空气滤清器或汽缸进气歧管的进气口。其电阻值随周围空气温度的变化而变化,从而发出不同电流值信号。如果进入发动机的空气温度低(或高)时,空气密度,即重量,会相应变大(或变小),传感器的这个信号将…
HPLC测定黄柏胶囊中盐酸小檗碱的含量

中国中药杂志 , 2003,
Abstract: 黄柏胶囊收载于中华人民共和国卫生部药品标准《中药成方制剂》第五册,系由中药材黄柏加工而成的单方制剂。具有清热燥湿,泻火除蒸,解毒疗疮之功效。用于湿热泻痢,黄疸、带下、热淋、脚气、盗汗、遗精、骨蒸痨热、疮疡肿毒,湿疹瘙痒等症[1,2]。由于原部颁标准制订时间较早,无含量测定项目,不利于该品种的质量控制。文献报道测定盐酸小檗碱含量的方法很多[14]。本文采用HPLC法测定黄柏胶囊中盐酸小檗碱分离效果好,灵敏、快

基于Bayesian理论的压缩视频超分辨率重构
,
南京师范大学学报(工程技术版) , 2005,
Abstract: 针对传统算法不能很好解决压缩视频的超分辨率图像重构问题,提出了一种基于Bayesian估计的压缩视频超分辨率重构算法.首先建立起一个从原始图像到压缩视频的成像模型,然后在此模型基础上运用Bayesian估计理论,在最大后验概率准则下表述该问题.通过综合使用CCD(CyclicCoordinateDecent)和SA(SuccessiveApproximations)等方法,从理论上给出了压缩视频超分辨率重构问题的一般解决方法.实验结果表明,此方法不仅在峰值信噪比(PSNR)和重构效果对压缩视频有较大提高和明显改善,而且算法易于扩展,具有广泛的应用范围.

Pure Mathematics (PM) , 2016, DOI: 10.12677/PM.2016.63024
Abstract:
G是有限π-可分群,HG的任意Hall π-子群,KG的子群。Alexandre Turull利用Hall π-子群的计算公式得到GHall π-子群H的个数可以被其子群KHall π-子群的个数整除这一关系。本文用初等方法证明了该结论。
Let G be a π-separable finite group, K and H respectively a subgroup and any Hall πsubgroup of G. Alexandre Turull gets the divisibility relation between the number of Hall π-subgroups of G and that of K by using the calculation formula about the number of Hall π-subgroup. It is obtained the form of certificate by using the elementary method.
我国判决说理激励机制适用问题之探讨
李拥军
- , 2018,
Abstract: 建立和完善我国判决说理的激励机制是《人民法院第四个五年改革纲要(2014―2018)》的重要内容。实践中,法官由于缺少解释权的正当性依据等原因而无法充分说理,很难依靠法律专业权威建立起内在动因式的激励机制。于是,以政治组织权威为动力的绩效考核成为判决说理激励机制的主要内容。但绩效考核是以外在动因为主的激励,其与判决说理规律存在逻辑悖论,存在欠缺普遍化和常态化的说理刚性机制、裁判文书评价标准模糊、评价主体单一、不能助力法官提高薪资与晋升等问题,激励效果与预期相差甚远。可见,政治组织性激励无法代替专业性激励。新一轮司法改革提出裁判文书上网和案例指导制度,取消了裁判文书签发制度,案件繁简分流制度以及智慧法庭建设为判决说理的专业性激励转型提供了良好的改革契机,逐渐成为法官说理的内在动因。
The establishment and improvement of the incentive mechanism of China??s judgment is an important part of “The 4th Five-Year Outline of the Program for Reform of People??s Courts (2014-2018)”. In practice, judges cannot fully reason due to reasons such as lack of justification for the right to interpret, and it is difficult to rely on the authority of legal profession to establish internal incentive mechanisms. Therefore, the performance appraisal based on the authority of political organization is the main content of the incentive mechanism of judgement reasoning. However, performance appraisal is an external motivation, so there is a logical paradox between it and law of reasoning, expressed as lack of the generalized and normalized rigid reasoning, vague evaluation criteria of judgment documents, and a single evaluation body, which do not help judges to increase salaries and promotions. Thus the incentive effect is far from expected. It can be seen that political incentives cannot replace professional incentives. The new round of judicial reforms put forward the system of referee??s Internet access and guiding case. The cancellation of the referee??s bookmarking system, the streamlining and shuffling of cases, and the construction of smart courts have provided a good opportunity for reforms in the professional reasoning of judgments and gradually become internal motivationto the judge??s reasoning.
