安全多方计算是解决隐私计算的重要手段,安全计算几何是安全多方计算的一大重要分支.其中,点与凸多边形的包含问题是一个重要的安全计算几何问题,在诸多领域呈现了极大的应用价值.然而现如今针对点与凸多边形包含问题的研究方案大都是在半诚实模型下设计的,因而不能抵抗恶意敌手攻击.本文分析了半诚实模型下点与凸多边形包含问题判定协议中可能存在的恶意攻击行为,包括恶意敌手提前知道结果而告知对方错误输出或终止协议等恶意行为.针对该恶意行为,利用Paillier加密算法,借助零知识证明和分割-选择方法等密码学工具,设计了恶意模型下点与凸多边形包含问题的判断协议.利用理想-实际范例证明了在恶意模型下该协议是安全的,与现有方案对比,不仅高效,而且可抵抗恶意敌手攻击,具有公平性.

开展校企合作是职业教育的基本办学模式。"校企学"法律关系在立法上定位较模糊,司法实践中操作也不完善。厘清三方权利义务分配,避免法律纠纷的发生极为重要。本文通过文献资料查询、司法判决文书分析等方法,对"校企学"三方的法律关系进行分析,并分析现行法律制度存在的不足,提出:国家法律政策层面应当将实习学生纳入劳动法调整范围,以最大限度维护各方利益;"校企学"三方应当根据其建立的不同法律关系性质,明确自身权利义务,防止法律纠纷的发生等对策建议。

Using entanglement swapping of high-level Bell states, we first derive a covert layer between the secret message and the possible output results of the entanglement swapping between any two generalized Bell states, and then propose a novel high-efficiency quantum information hiding protocol based on the covert layer. In the proposed scheme, a covert channel can be built up under the cover of a high-level quantum secure direct communication （QSDC） channel for securely transmitting secret messages without consuming any auxiliary quantum state or any extra communication resource. It is shown that this protocol not only has a high embedding efficiency but also achieves a good imperceptibility as well as a high security.

目的:探讨肿瘤相关成纤维细胞(CAFs)在调控胃癌细胞发生上皮间质转化(EMT)及迁移能力中的作用。方法:培养胃癌细胞系(SNU-1和MKN45)和原代成纤维细胞,分离和鉴定原代成纤维细胞;Western blot和实时定量PCR技术检测细胞内胸腺细胞分化抗原(Thy-1)的表达情况;并且建立胃癌细胞和CAFs共培养体系,将细胞分为胃癌细胞组、共培养体系组(空白对照组)、共培养体系+同型Ig G抗体组(阴性对照组)、共培养体系+抗Thy-1抗体组。Transwell实验检测Thy-1对共培养体系中胃癌细胞的迁移能力的影响;Western blot技术检测Thy-1对共培养体系胃癌细胞株的上皮(E-cad)及间质(N-cad和ZEB2)表型标记蛋白表达的影响。结果:成功分离CAFs,与正常成纤维细胞的形态并无明显差异,均出现纺锤形态,发现CAFs中α-平滑肌肌动蛋白(α-SMA)的表达比配对NFs细胞的表达量显著增加,提示分离出的CAFs可以作为后续相关实验研究;Western blot和实时定量PCR技术检测提示,CAFs中Thy-1的mRNA和蛋白质高表达,这与配对的NFs相比具有明显的统计学意义,且Thy-1在胃癌细胞系中低表达;CAFs与胃癌细胞共培养后,与胃癌细胞组相比,胃癌细胞系的迁移能力明显增强,且E-cad的表达显著降低,N-cad和ZEB2的表达明显升高,但共培养体系中CAFs预先孵育Thy-1抗体后,发现与阴性对照组相比,胃癌细胞系的迁移能力和EMT效应明显减弱。结论:CAFs细胞内过表达的Thy-1增强体外共培养体系中胃癌细胞的迁移能力和EMT效应。
