基于格的密码体系是后量子密码时代的重要研究方向,构造格上的盲签名方案具有重要意义.本文结合NIST后量子密码标准化项目的优胜算法Falcon,设计了一个NTRU格上紧凑型的盲签名方案.消息盲化时,用户先将签名者产生的320 bit均匀分布的随机比特串和一个本地均匀生成的等长随机比特串进行异或运算,得到真实签名组合中的320 bit长的随机值,实现该部分签名的盲性.接着用户计算原始消息拼接上新生成的随机向量的哈希值,然后将一个任意选取的整数和两个离散高斯分布随机选择的向量作为盲因子对哈希值进行盲化,实现消息对签名者的盲性.将原始消息与上述生成的均匀随机比特串做拼接的操作可以使得一个消息拥有多个合法签名.在“先哈希再签名”范式下,签名者利用快速傅里叶陷门采样器从NTRU格上寻找离其陪集上一点最近的格点,计算出符合要求的盲签名.用户对盲签名去盲后可以得到消息的合法签名.在随机谕言机模型下,基于NTRU格上SIS问题的困难性假设,证明本文方案满足强不可伪造性.依据效率分析,本文方案产生的公钥和签名组合尺寸较小,可以有效节约带宽资源.

加强东北地区经济联系有助于提升东北区域一体化水平,形成推动东北全面振兴的整体合力。基于修正后的引力模型和社会网络分析法对东北地区经济联系空间格局的演变特征进行分析,结果表明,东北地区经济联系网络整体密度呈先升后降的趋势,经济联系网络受省级行政区划的制约较为明显,同一省份内的城市经济联系更为密切。经济联系强度较强的地区主要集中在以沈阳市、大连市为中心的辽中南城市群,长春市、沈阳市、哈尔滨市三个省会城市的中心地位突出,黑河市、伊春市等资源枯竭型城市的经济联系强度偏弱,整体形成“南高北低”的分布格局,且网络重心具有向辽中南城市群移动的态势。促进制造业转型升级、提升市场需求、增强基础设施建设、加大对外开放力度有助于加强东北地区经济联系。

After launching a jet,outflows of magnetar were used to account for the achromatic plateau of afterglow and the early X-ray flux plateau known as“internal plateau”.The lack of detecting magnetic dipole emission together with the energy injection feature in a single observation poses confusion until the long gamma-ray burst(GRB)210610B is *** 210610B is presented with an optical bump following an early X-ray plateau during the afterglow *** plateau followed by a steep decline flux overlays in the steadily decaying X-ray flux with indexα_(X,1)~2.06,indicating an internal origin and that can be fitted by the spin-down luminosity law with the initial plateau luminosity log_(10)L_(X)~48.29 erg s~(-1)and the characteristic spin-down timescale T~2818 s.A subsequent bump begins at~4000 s in the R band with a rising indexα_(R,1)~-0.30 and peaks at~14125 s,after which a decay indexα_(R,2)~0.87 and finally transiting to a steep decay withα_(R,3)~1.77 achieve the closure relation of the external shock for the normal decay phase as well as the magnetar spin-down energy injection phase,provided that the average value of the photon indexΓ_γ=1.80 derived from the spectral energy distributions(SEDs)between the X-ray and optical *** closure relation also works for the late X-ray *** to the traditional picture of GRB,the outflow powers the early X-ray plateau by dissipating energy internally and collides with the leading decelerating blast burst as time goes on,which could interpret the exotic feature of GRB *** carry out a Markov Chain Monte Carlo simulation and obtain a set of best parameters:■.The artificial light curve can fit the afterglow data *** that,we estimated the average Lorentz factor and the X-ray radiation efficiency of the later ejecta are 35%and 0.13%,respectively.

碳纳米管作为新一代热界面材料,在天然材料中具有最高的热导率,有望解决金刚石半导体超高热流密度的散热问题.因此,本文提出将金刚石和碳纳米管结合,可大幅度提高器件性能及稳定性,减小封装尺寸,实现器件小型化设计.采用非平衡分子动力学方法从微观层面探究了金刚石/碳纳米管异质结构界面热特性及影响因素.研究发现碳纳米管层数增加使声子态密度峰值增大并向低频波段移动,低频声子增多更有利于界面传热,同时声子重叠能提高,声子耦合振动增强提升了界面传热效率;同时,一定范围内体系温度的升高及碳纳米管长径比的增大可以提高近界面处金刚石和碳纳米管的态密度截止频率,提升低频波段的峰值,进一步增强两侧声子的耦合振动,提高了界面热导.最后,采用正交试验模拟获得了金刚石/碳纳米管界面热导的最优值,结果远优于目前一般半导体/金属的界面热导.该工作为优化金刚石/碳纳米管异质界面的热输运提供了思路,并将有利于器件热管理和芯片材料设计.
