查询词典 key

This paper has obtained following three results about the new scheme:(1) The hardness of recovering the private key from the public key is based on the hardness of the shortest vector problems of several lattices;(2) The hardness of forging a signature is equivalent to the hardness of the closest vector problem of some lattice;(3) Each signature will leak information on the private key,but the final shape of the unlimited leakage is just a group of complicated non-linear equations.

文中给出新方案的3个结果：(1)由公钥恢复出私钥的困难性基于若干格上的最小向量问题；(2)由公钥伪造签名的困难性等价于某个格上的最近向量问题；(3)每个签名值仍然会泄露私钥的一些信息，但无限制泄露的最终形式只是关于私钥的一组复杂的非线性方程。

Started from D-tyrosine, we obtained the tetramic acid 96 using Jouin reaction. The assembly of the second fragment 109 was stared from 1,4-butandiol,using asymmetric alkylation reaction developed by Oppolzer as a key step. Coupling of the tetramic acid 96 with 109 provided the key intermediate 110 according to Yoshii\'s procedure. After remove protective group and Sharpless epoxidation, we obtained the key intermediate 113. Its macrocyclization to form the final product is in progress.

本论文的第二章主要对Macrocidin A开展了合成工作，我们从D构型的酪氨酸出发，经过官能团转换；利用Jouin反应生成Tetramic acid 96，另外一个片断从1，4-丁二醇开始经过多步反应生成碘化物104，利用Oppolzer发展的手性樟脑磺酰胺为辅基参与的不对称烷基化反应，引入手性甲基，生成关键中间体109，接着通过Yoshii发展的方法连接96和109生成110，经过Sharpless不对称环氧化反应建立环氧化合物，然后脱去保护基得到关环前体113，分子内的Mitsunobu反应进行关大环反应正在进行之中。

We strengthened energy conservation in key industries, enterprises and projects, and conducted pilot projects to develop the circular economy. We worked hard to prevent and control water pollution in key river valleys and regions, such as the Three Gorges Reservoir area, the Songhua River, the sources and routes of the South-to-North Water Diversion Project, and the Bohai Sea. We carried out key environmental protection projects to desulphurize emissions from coal-fired power plants, treat urban sewage and dispose of waste safely.
