身份认证是网络安全的一道重要防线,口令长期以来一直是身份认证的主流方式,口令攻击是口令安全研究的重要手段.基于概率上下文无关文法(Probabilistic Context-Free Grammar,PCFG)和基于Markov链的模型是目前效果最为显著的两类口令攻击方法,它们分别从子结构组成层面和字符前后依赖层面对口令进行有效地建模刻画.该文中,作者在综合上述两类模型优点的基础上提出了一种基于结构划分及字符串重组的口令攻击方法,记为SPSR模型:首先将口令划分成抽象的子结构,然后利用改进的Markov链模型生成子结构中字符、数字和符号等构成的子串,以同时兼顾模型的准确性和泛化能力.此外,作者在结构划分阶段还额外引入了常用字符段,并加入了索引位对特殊字符在口令中的位置进行了明确地刻画;在字符串重组阶段,通过递归的思想减少子串概率计算中的重复计算,给出了一个改进的OMEN算法——Recursive-OMEN算法.为了验证SPSR模型的有效性,分别在6个真实的中英文口令集上进行了实验测试.结果表明,按概率递减顺序生成相同规模的猜测口令集时,新提出的Recursive-OMEN算法比OMEN算法用时缩短了10倍左右;在相同的猜测次数下考察攻击效果时,SPSR模型比基于Markov链的模型能多破解出40%～50%的口令,比基于PCFG的模型能多破解出20%左右的口令.

Biosensors are a focus of research on terahertz metasurfaces. However, reports of ultra-sensitive biosensors based on Dirac points are rare. Here, a new terahertz metasurface is proposed that consists of patterned graphene and perovskites. This serves as an ultra-sensitive Dirac-point-based biosensor for qualitative detection of ***, sericin may make graphene n-doped and drive the Fermi level to shift from the valence band to the Dirac point, causing a dramatic decrease in conductivity. Correspondingly, the dielectric environment on the metasurface undergoes significant change, which is suited for ultra-sensitive biosensing. In addition, metal halide perovskites, which are up-to-date optoelectronic materials, have a positive effect on the phase during terahertz wave transmission. Thus, this sensor was used to successfully detect sericin with a detection limit of 780 pg/m L, achieved by changing the amplitude and phase. The detection limit of this sensor is as much as one order of magnitude lower than that of sensors in published works. These results show that the Dirac-pointbased biosensor is a promising platform for a wide range of ultra-sensitive and qualitative detection in biosensing and biological sciences.

目的为了拓宽聚环氧琥珀酸(PESA)的应用范围,合成了衣康酸改性聚环氧琥珀酸衍生物(IA-PESA),拟提高PESA的阻垢缓蚀性能。方法用顺酐合成环氧琥珀酸(ESA)和聚环氧琥珀酸(PESA),再利用ESA与衣康酸(IA)聚合制得IA-PESA,研究了IA-PESA的阻垢和缓蚀等综合性能。用FT-IR对PESA和IA-PESA进行表征。用黏度法测定了PESA和IA-PESA的分子量。结果在静态阻垢实验中,对CaCO_3.垢率达到90%以上,对CaSO_4阻垢率高达95%,甚至100%。IA-PESA分散Fe(Ⅲ)和稳定Zn^(2+)性能明显好于PESA。在静态失重实验中,当IA-PESA与PESA的用量均为150 mg/L时,加IA-PESA的腐蚀速率明显小于加PESA的腐蚀速率。对钙垢和腐蚀试片的SEM研究表明,IA-PESA使致密度较高、晶格结构规整的CaCO_3.CaSO_4钙垢改变为致密度较低、疏松、形状不规整的晶型结构。IA-PESA使试片未发生均匀腐蚀和点蚀,表面光滑。结论在相同测试条件下,IA-PESA的阻垢、缓蚀、分散Fe(Ⅲ)和稳定锌性能都好于PESA,改变了设备表面钙垢的晶型结构,减少了垢下腐蚀,缓蚀作用明显。

The fifth generation(5G) wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability,and guaranteed low latency. However, 5G will not meet all requirements of the future in 203. and beyond, and sixth generation(6G) wireless communication networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, better intelligence level and security, etc. To meet these requirements, 6G networks will rely on new enabling technologies, i.e., air interface and transmission technologies and novel network architecture, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing. Our vision on 6G is that it will have four new paradigm shifts. First, to satisfy the requirement of global coverage, 6G will not be limited to terrestrial communication networks, which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV) communication networks, thus achieving a space-airground-sea integrated communication network. Second, all spectra will be fully explored to further increase data rates and connection density, including the sub-6GHz, millimeter wave(mmWave), terahertz(THz),and optical frequency bands. Third, facing the big datasets generated by the use of extremely heterogeneous networks, diverse communication scenarios, large numbers of antennas, wide bandwidths, and new service requirements, 6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI) and big data technologies. Fourth, network security will have to be strengthened when developing 6G networks. This article provides a comprehensive survey of recent advances and future trends in these four aspects. Clearly, 6G with additional technical requirements beyond those of 5G will enable f
