3863	针对现有的逆向频谱拍卖没有考虑与频谱有关的非价格属性的问题和频谱拍卖安全问题，提出了一个面向隐私保护的多属性逆向频谱拍卖方案。	Aiming the problem that the existing reverse spectrum auctions do not take the non-price attribute of spectrum into account and the security of spectrum auction, a privacy-preserving multi-attribute reverse spectrum auction was pro-posed.
3864	首先，将含有频谱价格、与频谱有关的非价格正向属性值作为频谱竞标人的竞标方案并执行拍卖判断频谱赢家。	Firstly, price and non-price positive attributes of spectrum were considered as the bidding scheme of bidders andauctions was performed to judge spectrum winners.
3865	其次，为确保频谱拍卖的安全性，方案利用 Paillier 门限机制引入一组拍卖人的分治集中式频谱拍卖服务器代替传统单一的第三方代理机构，防止频谱拍卖人与频谱竞标人的“合作欺诈”。	Secondly, to ensure the security of the spectrum auction, the Paillier threshold system was used to introduce a group of spectrum auction servers of auctioneers to replace the traditional singlethird-party agency, which could prevent the fraud collusion between spectr u m auctioneers and bidders.
3866	所提方案还引入匿名化技术、不经意传输技术的密码学工具，确保频谱拍卖的安全特性，使频谱拍卖安全地执行。	The cryptography tools such as the anonymization technology and oblivious transfer were introduced to achieve the secure features, which could make the spectrum auction performed securely.
3867	对所提方案的安全协议进行安全分析表明，协议具有较强的安全性。	The security analysis shows that the security protocol has strong security.
3868	对协议进行性能评估，实验结果表明，所提方案在计算开销上优于可应用在频谱拍卖场景下的多属性逆向拍卖安全方案。	The performance of the protocol is also evaluated, and experimental results show that the security scheme is su-perior to the multi-attribute reverse auction security scheme that can be applied in the spectrum auction scenario in termsof computational overhead.
3869	为在双单播网络中运用网络编码技术进行数据传输，提出了一种双单播网络编码的构造方法。	In order to use network coding technology for data transmission in double unicast network, a constructionmethod of double unicast network coding was proposed.
3870	所提方法在源点实施预编码策略，采用随机线性网络编码方法并结合多目标优化进化算法来设计各信道的局部编码向量；	The pre-coding strategy was implemented at each source node,the random linear network coding combined to the multi-objective optimization evolutionary algorithm was adopted todesign the local coding vector of each channel.
3871	在宿点运用矩阵零空间的基向量来消除部分信息干扰，再运用二级预编码策略来控制源点的发送速率，从而能够解码。	At the each sink node, the base vector of zero space of matrix was used to eliminate some information interference, and then the two-level pre-coding strategy was used to control the transmissionrate at source. Thus, each sink node could be decoded successfully.
3872	所提方法不仅能确定双单播网络编码的近似可达信息率区域，还能为可达信息率区域中的每一向量构造可行的传输方案。	With the proposed method, the approximate reachable information rate region of double unicast network coding could be determined and the transmission scheme for each vec-tor in the reachable information rate region could be designed.
