17755 内积加密是一种支持内积形式的函数加密,已有内积加密方案的公开参数规模较大, Inner product encryption is a kind of function encryption which supports inner product form. Thepublic parameter scale of the existing inner product encryption schemes are large.
17756 为解决该问题,该文基于素数阶熵扩张引理,利用双对偶向量空间(DPVS)技术,提出一个公开参数规模较小的具有适应安全性的内积加密方案。 In order to solve this problem, based on prime-order bilinear entropy expansion lemma and Double Pairing Vector Space (DPVS), an inner product encryption scheme is proposed in this paper, which has fewer public parameters and adaptive security.
17757 在方案的私钥生成算法中,将用户的属性向量的分量与主私钥向量结合,生成一个可与熵扩张引理中密钥分量结合的向量;在方案的加密算法中,将内积向量的每一分量与熵扩张引理中的部分密文分量结合。 In the private key generation algorithm of the scheme, the components of the user’s attribute with the main private key are combined to generate a vector that can be combined with the key components in the entropy expansion lemma, and in encryption algorithm of the scheme, each component of the inner product vector is combined with cipher text component in the entropy expansion lemma.
17758 在素数阶熵扩张引理和困难假设成立条件下,证明了方案具有适应安全性。 Finally, under the condition of prime order bilinear entropy extension lemma and  difficult assumption, the adaptive secure of the scheme is proved.
17759 该文方案公开参数仅有10个群元素,与现有内积加密方案相比,公开参数规模最小。 The proposed scheme has only 10 group elements as public parameters, which is the smallest compared with the existing inner product encryption schemes.
17760 无线紫外光通信成为强电磁干扰下的有效通信手段,满足复杂战场环境下车队执行战略物资运输和弹车队隐蔽行驶时车辆间保持可靠隐秘通信的需求。 Wireless ultraviolet communication becomes an effective means of communication under strong electromagnetic interference, which meets the need of reliable and secret communication between vehicles when the fleet performs strategic material transportation and the missile vehicle fleet of concealed driving vehicles in a complex battlefield environment.
17761 在行驶中每辆车自身作为其它车辆的中继,通过多跳方式为非视线内车辆之间建立稳定可靠的通信链路。 Each vehicle acts as a relay for other vehicles while driving, and establishesa stable and reliable communication link between non-line-of-sight vehicles through a multi-hop model.
17762 因此,基于紫外光单次散射模型,该文研究了最优多跳中继问题,理论分析了收发仰角与频谱效率的关系,依据使频谱效率最大化原则,得出最优跳数近似表达式。 Therefore, based on the single-scattering model of ultraviolet, the optimal multi-hop relay problem is studied, and the relationship between the elevation angle of the transmitting and receiving and the spectral efficiency is theoretically analyzed. According to the principle of maximizing the spectral efficiency, the approximateexpression of the optimum number of hops is obtained.
17763 仿真结果表明,不同距离移位范围和不同收发仰角都对应特定的最优跳数值,与最优能量计算方法相比,最大频谱效率计算方法在小功率传输时有更好的传输能力,并且达到节约功率的需求。 The simulation results show that the optimum numberof hops correspond to different distance shift range and elevation angles. Compared with the optimum energycalculation method, the proposed method has better transmission capability in low power transmission andachieves the requirement of power saving.
17764 紫外光长距离通信时,系统性能并不随着协作中继数的增加而提高,选取合适的中继数及小发射仰角和大接收仰角的结构配置,系统可获得较高的传输能力。 In the long-distance ultraviolet communication, system performancedoes not increase with the number of cooperative relays. The system can obtain a higher transmission capacityby selecting a suitable number of relays and a small transmission elevation angle and a large receiving elevation angle.
