Digital Wiretap Warrant: Improving the security of ETSI Lawful Interception

Lawful Interception (LI) of data communications is an essential tool for Law Enforcement Agencies (LEA) in order to investigate criminal activities carried out or coordinated by means of Internet. However, the ability to secretly monitor the activities of citizens also has a great impact on civil rights. Therefore, democratic societies must prevent abuse and ensure that LI is only employed in specific cases with justifiable grounds or a probable cause. Nowadays, in many countries each interception must be authorized by a wiretap warrant, usually issued by a judge. However, this wiretap warrant is merely an administrative document that should be checked by the network or service operator before enabling the monitoring of its customers, whose communications are later handed over to a LEA in plaintext. This paper proposes the idea of employing a Digital Wiretap Warrant (DWW), which further protects the civil liberties, security and privacy of LI by ensuring that monitoring devices can only be enabled with a valid DWW, and by encrypting the captured data so only the authorized LEA is able to decrypt those communications. Moreover, in the proposed DWW framework all digital evidence is securely time-stamped and signed, thus guaranteeing that it has not been tampered with, and that a proper chain of custody has been met. In particular this paper proposes how to apply the DWW concept to the lawful interception framework defined by the ETSI LI Technical Committee, and evaluates how the additional security mechanisms could impact the performance and storage costs of a LI platform.

The Management of Democratic Elections in Africa (MDEA) programme at the university of South Africa: Is this the right path towards African solutions?

There have been a number of initiatives in Africa to rid the Continent of political instability, conflict, poverty and disease. Many have argued that aid from the West has helped Africa in many ways—from stopping wars, to food relief and rescuing the African environment. Yet others have slated Western involvement which they contend, frequently leaves Africans dependant rather than capable of solving their own problems. In line with the pan-Africanist and the African Union (AU) ideals, there is now a realisation by Africans that there is a need to find African solutions to African challenges and problems. This review article explores the University of South Africa’s (Unisa’s) Management of Democratic Elections in Africa (MDEA) programme, by looking at its objectives and the reason why it must be labelled a Programme, its mandate, which is in line with the brief of the AU and pan-Africanist ideals. The article focuses on how Unisa’s programme responds to the African Charter on Democracy, Elections and Governance (ACDEG); and how it has attempted to facilitate knowledge for peace in Africa, through empowering electoral officials from various African states. The article concludes by looking at the successes and limitations of the Programme over a five-year period, from its inception in 2011.     

和谐社会视域下的国企工人道德素质现状及对策研究

依据中国公民人文素质调查数据库对我国国企工人道德素质从道德意识、道德常识、道德行为三个维度进行综合分析,结果表明:(1)国企工人道德素质整体水平较高,但在道德意识上存在倒置和不平衡等差异现象。(2)国企工人道德素质结构性差异不均衡,学历和工龄对其作用以直接作用为主。     

沿海十省(市)药品监管机构能力之比较研究

在构建社会主义和谐社会的当代中国,药品的安全性和有效性正日益引起人们的关注,而药品监管机构能力的建设与评估也开始成为社会监管领域的重要问题.通过回顾国内外已有的对政府能力概念和要素的研究,借用Nelissen的潜在能力和现实能力理论,结合世界银行2003年《世界发展报告》中对机构现实能力的要素分析和"行政储备"理论对机构潜在能力的要素分析,构建起药品监管机构能力的结构模型,并提出一套评估的指标体系.对数据进行标准化处理后,通过统计排序对沿海十省(市)药品监管机构能力进行评估和比较,进而利用最小二乘法(OLS)建立回归模型,分析潜在能力中的财力和人力因素对现实能力的贡献率.研究发现:地区财力对监管机构现实能力的影响较之人力因素要大,这在理论和实践中都可以得到证实;各地药品监管机构的潜在能力与现实能力之间存在较大差异,就那些现实机构能力较低的地区而言,现阶段有必要把工作重点放在医药企业生产经营行为的监管和农村地区医药监管基础设施的建设上;而对于潜在机构能力较低的地区来说,从"专业化、程序化和独立性"等方面提升机构整体的人力资源是当务之急.     

两大法系陪审制度比较研究

西方国家的陪审制度有两种运作模式,一种是英美法系的陪审团制,另一种是大陆法系的参审制。这两种陪审制度的主旨都在于吸收普通民众参与诉讼,从而将“民间智慧”和“大众理性”引入司法领域,但是,在具体的制度设计上,二者之间则存在着明显的差异。这些差异的形成,与两大法系各自的司法制度和法律文化传统密切相关。

The Impact of Language Status as an Acculturative Stressor on Internalizing and Externalizing Behaviors among Latino/a Children: A Longitudinal Analysis from School Entry through Third Grade

This study examined the relationship between limited English proficiency status, and internalizing and externalizing behaviors among a sample of Latino/a children (N = 2,840) from the US Department of Education’s Early Childhood Longitudinal Study, Kindergarten (ECLS-K) data set. Results of cross sectional regression and hierarchical linear modeling (HLM) analyses suggest that there is a positive relationship between limited English proficiency and externalizing symptoms, particularly by third grade. Additionally, sex and place of birth also helped to explain externalizing behaviors at various time points in the models. Place of birth and family poverty were significantly associated with internalizing symptoms. Implications for future research and interventions related to internalizing and externalizing behavior among the Latino/a school aged population are discussed.

古代中国与朝鲜的“气”哲学传统比较

在中国,元气自然论在王充以后,受魏晋玄学思辩哲学的压抑一度发展低迷,到北宋张载时走向高峰而发展为元气本体论,后又受程朱"理"论的排挤,一度衰微。300年后,王廷相、王夫之的气论又形成发展高潮。在朝鲜,确立气一元论哲学的徐敬德之后,气哲学传统就表现为主理主气之争、唯理唯气之争,最终由崔汉绮总集成。中国的气论主要作为宇宙本根论,道器、形而上、形而下等范畴始终成为诠释的中心。朝鲜的气论则更多地是对心、性、情等伦理本体的探讨,故主要围绕理气、心性、善恶等概念进行了研究。     

论韩国在现代世界经济体系中地位的变迁

二战结束后,美国出于地缘政治战略考虑,把韩国纳入到现代资本主义经济体系,成为该体系的"边缘区";经过漫长的经济积累,在80年代末、90年代初,韩国终于进入"半边缘区",直至今日。目前,韩国在追赶美国、日本的同时,也在被"北方国家"追赶。在这种"多层追赶"的态势中,韩国必须寻找最佳的对策,确保并提升自己在现代世界经济体系中的地位。
