基于移动代理的新型IDS维护更新机制设计

提出了一种基于移动代理的新型分布式入侵检测系统。该系统是针对广域网环境专门设计的,数据的处理通过各节点所设置的代理来进行分布式计算,不仅能实现全网络范围内的入侵检测功能,具有良好的可移植性;而且对网络系统和主机的资源占用较低,减少了出现网络瓶颈的可能。还建立了移动代理的新型分布式入侵检测系统的体系结构和理论分析模型,并讨论了该系统的维护更新机制。     

手机短信诈骗及治理对策

随着手机短信业务的发展，利用手机短信进行诈骗的现象也频繁发生。短信诈骗行为的泛滥，不仅严重侵犯了人们的财产权益，而且破坏了正常的社会经济秩序。为有效预防和遏制手机短信诈骗，应强化监管和打击，建立和完善手机号码实名制和储蓄实名制，加强宣传教育，多管齐下，进行综合治理。     

论电信企业客户信用管理系统的构建

电信业发展过程中,呆坏账是一个普遍的问题,而且给电信企业的经营也带来了不小的影响。尽管形成我国电信呆坏账的原因有许多,但信用大环境的缺失和电信企业对客户信用管理的不足是最主要的方面。电信企业应在清醒认识信用本体和自身管理方面不足之后,采取措施,逐步建立起有效、动态的企业客户信用管理系统,改善当前的信用管理,才能较好地解决问题。

战术移动通信网的频率复用技术研究

战术移动通信网的网络拓扑结构随战场环境的变化而变化,为此网络拓扑结构具有重组的能力,网络拓扑重组后必须进行链路频道的重新分配,文中提出的频道分配技术是在避免同频道干扰条件下任一频道可在全网内多次重复使用,以提高频道的重复利用率,同时分析了该情况下网络至少应拥有的频道数,以保证网络有足够的频道供分配。     

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.     

基于修正UTAUT模型的农信社手机银行使用行为研究——以福建省农户调查数据为例

基于UTAUT模型,引入感知风险、替代软件等2个变量进行修正,构建农信社手机银行使用行为影响因素研究模型,并运用结构方程模型、Bootstrap中介检验、多群组分析等方法对福建省农户调查数据进行实证分析。研究发现:(1)感知易用性显著正向影响农信社手机银行使用意愿;感知风险和替代软件显著负向影响农信社手机银行使用意愿;社会影响对农信社手机银行使用意愿影响不显著。(2)便利条件和使用意愿显著正向影响农信社手机银行使用行为;农信社手机银行使用行为影响因素由大到小依次为便利条件、替代软件、感知风险、感知易用性。(3)教育在感知易用性对农信社手机银行使用意愿影响中具有调节作用。据此提出,应进一步增强操作的便利性以优化业务办理效率,增强信息的安全性以降低软件使用风险,增强软件的特色性以降低软件可替代性,增强软件的易用性以优化便捷使用体验,从而优化农村金融服务供给,助推农村经济发展。     

Permanently online and permanently connected: Taiwanese university students’ attachment style,mobile phone usage,and well-being

Taiwan has been the top country worldwide in terms of its adoption and use of mobile phones. This study explores the permanently online (PO) and permanently connected (PC) phenomenon in mobile phone use among Taiwanese university students. It seeks to determine whether attachment styles are a distinctive factor that influences PO and PC (POPC) behavior and leads to various levels of well-being. The results of this study provide initial evidence that Taiwanese users highly depend on their mobile phones for PC and PO activities but perceive that being permanently connected causes interpersonal stress. Although the findings showed that all styles were positively associated with PO, only the secure and anxious styles predicted PC. Regarding mobile phone activities, the avoidant attachment style was not associated with any activities, the secure attachment style was positively associated with online and voice communication as well as information-seeking activities, and the anxious attachment style was associated only with voice communication. Furthermore, attachment styles lead to various levels of interpersonal stress through PO and PC behavior. The anxious style interacts with PO on interpersonal stress. This study provides evidence that attachment style is a significant antecedent of POPC and its consequences in mobile phone usage.     

Who is a Distracted Driver? Associations between Mobile Phone Use while Driving,Domain‐Specific Risk Taking,and Personality

Mobile phone use while driving (MPUWD) is an increasingly common form of distracted driving. Given its widespread prevalence, it is important for researchers to identify factors that may predict who is more likely to engage in this risky behavior. The current study investigates associations between MPUWD risk behaviors, domain‐specific risk perceptions, and broad personality dimensions. An Italian community sample (n = 804) completed a survey regarding MPUWD risk perceptions and engagement in MPUWD, in addition to the HEXACO‐PI‐R, a broad six‐factor personality inventory (honesty‐humility, emotionality, extraversion, agreeableness, conscientiousness, openness to experience), and the DOSPERT, a six‐factor domain‐specific self‐report risk‐taking measure (health/safety, recreational, social, ethical, gambling, and investment). With respect to domain‐specific risk taking, greater frequency of SMS use while driving most strongly was associated with greater risk taking for the health/safety, gambling, and ethical risk domains. Further, greater honesty‐humility and conscientiousness, two traits related to cognitive control and risk behaviors, and to a lesser extent openness to experience, were associated with less frequent MPUWD, and positively associated with MPUWD risk perceptions. With growing public safety concern surrounding MPUWD, understanding associated personality factors is not only important for identifying psychological mechanisms underlying risk behavior, but also for more effective prevention and intervention programs.
