随着量子计算的快速发展,特别是Shor量子算法及其变体的优化进步,当前基于大整数分解和离散对数问题的经典公钥密码体制将面临颠覆性的影响.为了应对量子攻击,学界开始对后量子密码学的研究,其中基于格的后量子密码方案因其在安全、效率、带宽等方面的均衡表现和良好的可扩展性而成为后量子密码的主流技术路线.目前,基于格的后量子密码方案大多使用分圆环,尤其是二次幂分圆环作为底层代数结构.但分圆环中具有丰富的子域、自同构、环同态等代数结构,容易遭受针对性攻击.基于具有“高安全性、素数阶、大Galois群和惰性模数”特点的素阶数域,设计出后量子数字签名方案Dilithium-Prime,并给出推荐参数集.然而,素阶数域的一个显著缺点是无法直接使用快速数论变换(NTT)算法进行高效的多项式乘法,导致素阶数域上的密码方案性能较差.为此,设计素阶数域上的NTT算法和小多项式乘法,实现素阶数域上高效的多项式乘法.最后,为方案的关键算法设计常数时间无分支实现方法,给出方案的C语言实现,并与其他方案进行对比.实验结果表明,在同一安全等级下,与分圆环上的数字签名方案CRYSTALS-Dilithium推荐参数相比,Dilithium-Prime方案的公钥尺寸、私钥尺寸、签名尺寸分别降低1.8%、10.2%、1.8%,签名算法效率提高11.9%,密钥生成算法、验证算法所需时间分别为CRYSTALS-Dilithium方案的2.0倍和2.5倍,但不同于CRYSTALS-Dilithium,Dilithium-Prime方案具有抵抗针对分圆环的密码攻击的优越特性;与2023年韩国后量子密码算法竞赛中提出的基于素阶数域的签名方案NCC-Sign推荐参数相比,在相同的安全等级和带宽条件下,Dilithium-Prime方案的密钥生成算法、签名算法、验证算法的速度分别提升至4.2倍、35.3倍、7.2倍,实现兼顾高效性和安全性的素阶数域签名算法.

Weakly electric fish has an ability to generate a low-frequency electric field actively to locate the surrounding object in complete darkness by sensing the change of the electric field. This ability is called active electrolocation. In this paper, we designed a two-dimensional （2D） experimental platform of underwater active electrolocation system by simulating weakly electric fish. On the platform, location characteristics based on frequency domain were investigated. Results indicated that surface shape of 3D location characteristic curves for the 2D underwater active electrolocation positioning system was convex upwards or concave down which was influenced by the material of probed objects and the frequency of the electric field exci- tation signal. Experiments also confirmed that the amplitude of the electric field excitation signal and the size of the probed object will only influence the amplitude corresponding to 3D location characteristic curves. Based on above location charac- teristics, we present three location algorithms including Cross Location Algorithm （CLA）, Stochastic Location Algorithm （SLA） and Particle Swarm Optimization （PSO） location algorithm in frequency domain and achieved the task of the underwater positioning system. Our work may have reference value for underwater detection study.

Lightweight fault localization(LFL), which outputs a list of suspicious program entities in descending order based on their likelihood to be a root fault, is a popular method used by programmers to assist them in debugging. However, owing to the nature of program structures, it is impossible for LFL to always rank the root faulty program entity at the top of a ranking list. Recently, Xia et al. noted in their study that programmers inspect the first top-K-ranked program entities outputted by an LFL tool in sequence. Therefore,it is of practical significance to further improve the absolute rank of those buggy programs by using LFL if the root fault is ranked higher. To solve this issue, we propose a new LFL combined with a fault context to improve the fault absolute rank. We conduct experiments in which we apply our proposed approach to seven Siemens benchmark programs. The results show that by combining the suspiciousness scores of program entities with their fault-context suspiciousness scores that are based on an LFL called Dstar, our approach can improve the fault absolute rank with an effectiveness rate of 35.7% for 129 faulty versions from the seven benchmark programs. It should be noted that our approach can obtain an average improvement of 65.18% for those improved programs to which LFL can be effectively applied, and that there were improvements to seven top-ranked root faults of buggy programs.

A Reduced-dimensional spherical harmonics MUSIC(RD-SHMUSIC) is proposed to solve the problem of high computational complexity of Multiple signal classification(MUSIC) algorithm for Twodimensional(2-D) Direction of arrival(DOA) *** proposed algorithm first expresses the spherical harmonic steering vector as a linear weight of a uniform phase vectors. Via the Lagrange multiplier method, we can get a new search function to estimate elevations. At second step, the algorithm expresses the steering vector in another form, a linear weight of a vector which is constructed by associated Legendre functions. A search function to estimate azimuths can also be *** proposed method only needs One dimensional(1-D) angle search, which means it has a large reduction of computational complexity compared to the traditional Spherical harmonics MUSIC(SHMUSIC). The simulation results show that the accuracy of the proposed method is better than Two-stage decoupled approach(TSDA)algorithm, and has close performance to that of SHMUSIC.

This paper considers the Cohen-Grossberg BAM neural networks(CG-BAMNNs) on time scale, which can unify and generalize the continuous and discrete systems. First, the criteria for the existence and uniqueness of the equilibrium of CG-BAMNNs are derived on time scale. Then based on that, the authors give the criteria for the stability and estimation of equilibrium of the CG-BAMNNs on time scale. The method proposed in this paper unifies and generalizes the continuous and discrete CGBAMNNs systems, and is applicable to some other neural network systems on time scale with practical meaning. The effectiveness of the proposed criteria for delayed CG-BAMNNs is demonstrated by numerical simulation.
