In some schemes, quantum blind signatures require the use of difficult-to-prepare multiparticle entangled states. By considering the communication overhead, quantum operation complexity, verification efficiency and other relevant factors in practical situations, this article proposes a non-entangled quantum blind signature scheme based on dense encoding. The information owner utilizes dense encoding and hash functions to blind the information while reducing the use of quantum resources. After receiving particles, the signer encrypts the message using a one-way function and performs a Hadamard gate operation on the selected single photon to generate the signature. Then the verifier performs a Hadamard gate inverse operation on the signature and combines it with the encoding rules to restore the message and complete the *** with some typical quantum blind signature protocols, this protocol has strong blindness in privacy protection,and higher flexibility in scalability and application. The signer can adjust the signature operation according to the actual situation, which greatly simplifies the complexity of the signature. By simultaneously utilizing the secondary distribution and rearrangement of non-entangled quantum states, a non-entangled quantum state representation of three bits of classical information is achieved, reducing the use of a large amount of quantum resources and lowering implementation costs. This improves both signature verification efficiency and communication efficiency while, at the same time, this scheme meets the requirements of unforgeability, non-repudiation, and prevention of information leakage.

随着虚拟空间和数据交互技术的深入发展,人格数据的属性变化引发了在数据确权理论上的“权益论”和“权利论”的分歧,并由此导致当前数据跃迁、信息膨胀和数据价值失衡等现实问题。透过对前述两种理论的比较研究,人格数据权益相较于权利而言,存在权利归属限制和核心法益缺失等问题;而鉴于数据人格权符合主体性差异、立法例比较和独立性权利证成三要素之基本要求,亦可从“权利-行为”的规制模式中探索数据人格权与隐私权、个人信息权之边界,并在当前技术发展阶段内从主体规制与场域突破两方面协调数据人格权与传统人格权之间的关系,以数据人格权作为具体人格权规范的有益补充,在未来虚拟空间技术发展到人格拟态阶段和局域空间自制时,于虚拟空间内逐步取代隐私权、个人信息权等部分具体权利。同时,在数据人格权的法律关系上又以积极权能和消极权能的划分为视角,结合数据场景化应用流通图示的方式,构建其基本权利和系统性义务的内容,而后围绕着构建人格数据产业系统,逐步探索和建立人格数据分类分级制度、人格数据库制度和以人格数据业务为代表的数据银行制度,实现人格数据规范、安全和享益的价值理念,以期构建多元虚拟空间数据信息交互平台背景下的人格数据保护规制体系。

本研究旨在探究不同温度下添加不同浓度苯乳酸(Phenyl lactic acid,PLA)对玉米(Zea mays L.)秸秆青贮饲料发酵品质、抗生素抗性基因(Antibiotic resistance genes,ARGs)和可移动遗传元件(Mobile genetic genes,MGEs)丰度变化的影响。采用双因素(苯乳酸×温度)完全随机设计,温度设定20℃和30℃,苯乳酸设置添加组(0.2%PLA和0.4%PLA)和对照组(CK),30 d后取样分析青贮品质。结果显示,与对照组相比,随着PLA浓度增加,两种温度下的pH值、乳酸菌数量和乙酸含量均显著增加(P<0.05)。酵母菌数量随着PLA浓度增加而增加,而乳酸和氨态氮含量随之下降。与20℃相比,30℃条件下自然青贮的玉米秸秆饲料pH值显著增加,乳酸菌数量显著下降(P<0.05)。本试验所检测的ARGs属于大环内脂类、磺胺类和四环素类抗性基因,添加PLA发酵30 d后,与对照组相比,这些ARGs和MGEs绝对丰度均显著下降(P<0.05),其中sul1,sul2,sul3,ermB,tetC与Tn916/1545丰度变化趋势相似,Pearson相关性分析发现两者之间具有极显著正相关关系(P<0.01)。综上,两种温度条件下,添加PLA对玉米秸秆青贮发酵品质均具有改善作用,可以减少ARGs的污染。
