Distributed cipher chaining for increased security in password storage

Odelberg, David, Holm, Carl Rasmus January 2014 (has links)
As more services move on to the web and more people use the cloud for storage of important information, it is important that providers of such services can guarantee that information is kept safe. The most common way of protecting that data is to make it impossible to access without being authenticated as the user owning the data. The most common way for a user to authenticate and thereby becoming authorized to access the data, or service, is by making use of a password. The one trying to safeguard that password must make sure that it is not easy to come by for someone trying to attack the system. The most common way to store a password is by first running that password through a one way function, known as a hash function, that obfuscates it into something that does not at all look related to the password itself. Whenever a user tries to authenticate, they type in their password and it goes through the same function and the results are compared. While this model makes sure that the password is not stored in plain text it contains no way of taking action in case the database of hashed passwords is leaked. Knowing that it is nearly impossible to be fully protected from malevolent users, the ones trying to safe guard information always need to try to make sure that it is difficult to extract information about users' passwords. Since the 70s the password storage has to a large extent looked the same. What is researched and implemented in this thesis is a different way of handling passwords, where the main focus is on making sure there are countermeasures in case the database leaks. The model described and implemented consist of software that make use of the current best practices, with the addition of encrypting the passwords with a symmetric cipher. This is all done in a distributed way to move towards a paradigm where a service provider does not need to rely on one point of security. The end result of this work is a working proof-of-concept software that runs in a distributed manner to derive users' passwords to an obfuscated form. The system is at least as secure as best current practice for storing users passwords but introduces the notion of countermeasures once information has found its way into an adversary's hands.

AU-Led Peace Operations : The Case of the AMISOM KDF’s Local Peacebuilding Engagement in Southern Somalia, Jubbaland Region

Emil, Thillberg, Philip, Martinsson January 2020 (has links)
Contemporary peace operations are deployed to increasingly complex, high-risk environments where localised armed groups, often those that can influence the trajectory of the conflict are not at the table, at the same time militaries are mandated to facilitate social, economic and political transformative processes in recovered areas. By the opening of the twenty-first century, the distinction between peacebuilding and military interventions converged both in policy and practice and increasing pressure are placed on the troop-contributing countries to adapt to the dynamics of ‘multidimensional peace operations. Drawing upon the intersection between the academic bodies of peacekeeping and counter-insurgency, this research argues that there is a growing amount of empirically grounded literature that seeks to critically assess missions’ peacebuilding capability, and more specifically its impact on local settings. Yet, most studies tend to be framed in relation to conflict abatement along reductionist approaches to development rather than analysing how and in what ways such missions aid in providing a stable polity, thus suggesting a need of further investigation about the phenomena. In contribution to the community of practice(s), this research draws upon the latest theoretical trend of peacebuilding, abiding to a system perspective of the 5 Capabilities Framework (5Cs). This, in order to attain an increased understanding of military actors’ involvement and ability to undertake early peacebuilding tasks, by studying the case of the Kenyan Defence Force (KDF) under the auspices of African Union Mission in Somalia (AMISOM) in the Jubbaland region. Moreover, the research was operationalised through an on-ground collection of data in Kenya and Somalia, using unstructured and semi-structured interviews and draws upon a purposive sampling method to gather perspectives from a variety of actors involved in peace operation affairs. The study finds that the AMISOM KDF has played a key role in shaping the organisation’s peacebuilding policy, with a diverse portfolio engagement of both top-down and bottom-up character. Working predominantly through informal structures, much of their engagement is not aligned with the AMISOM civilian headquarters, in response to an environment with many challenges, resulting in a patchwork of practices with sectoral difference. Analytically, the 5Cs framework posit that an organisation must strike a balance between all capabilities in order to produce social value, something that the Kenyan contingents have struggled to achieve. While this unpacks a view of moderate, to low capacity for peacebuilding, it also generates an overall critique to the framework as it promotes a scenario which seems impossible to realise. Despite its ‘system-wide’ contribution, questions remain regarding the value of the framework in analysing local peacebuilding engagement in peace operations.
