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.     

Postmortem Computed Tomography in Firearm Homicides: A Retrospective Case Series,

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.     

Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.     

Enabling collaborative synthesis in multi-partner programmes

Multi-partner consortia have emerged as an important modality for knowledge generation to address complex sustainability challenges. Establishing effective multi-partner consortia involves significant investment. This article shares lessons from the Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA), which aims to support policy and practice for climate change adaptation through a consortium model. Key lessons include the need to facilitate collaborative spaces to build trust and identify common interests, while accepting that this is not a guarantee of success; the importance of programmatic leadership to achieve synthesis; and the value of strategic planning in supporting motivation and alignment between partners.     

Investing in multi-stakeholder dialogue to address natural resource competition and conflict

How can multi-stakeholder dialogue help assess and address the roots of environmental resource competition and conflict? This article summarises the outcomes and lessons from action research in large lake systems in Uganda, Zambia, and Cambodia. Dialogues linking community groups, NGOs and government agencies have reduced local conflict, produced agreements with private investors, and influenced government priorities in ways that respond to the needs of marginalised fishing communities. The article details policy guidance in four areas: building stakeholder commitment, understanding the institutional and governance context, involving local groups in the policy reform process, and embracing adaptability in programme implementation.     

Changing knowledge and perceptions of African indigenous vegetables: the role of community-based nutritional outreach

African indigenous vegetables (AIVs) have potential to sustainably address malnutrition, a growing problem in sub-Saharan Africa. Their consumption is however, limited by poor perceptions and lack of awareness of nutritional benefits. There is limited evidence of the effectiveness of community-focused information dissemination approaches in influencing participants’ perceptions and uptake of innovations in AIVs to address malnutrition. This article aims to fill this knowledge gap, using a case study focusing on pastoral communities in Monduli district in northern Tanzania. Target communities participated in a community-based nutritional outreach facilitated by the Good Seed Initiative (GSI), held at Monduli district hospital in September 2014. The results provide evidence of the achievements of the GSI intervention, and the effectiveness of alternative information dissemination approaches.     

The Malian fertiliser value chain post-subsidy: an analysis of its structure and performance

This article examines the structure of the Malian fertiliser value chain and its performance in the context of the national subsidy programme, drawing on a review of the literature, farm household survey, and interviews with fertiliser suppliers. It finds that participants in the subsidy programme use more fertiliser and have significantly higher yields. The number of wholesalers and retailers has risen, but procurement remains concentrated. Poor fertiliser quality is a recurrent problem. The high cost of the programme raises questions regarding its sustainability. Mixed performance reflects the need for better monitoring and evaluation, and transparency in the programme.
