Bingo: A Semi-Centralized Password Storage System

Abstract

A lack of security best practices in modern password storage has led to a dramatic rise in the number of online data breaches, resulting in financial damages and lowered trust in online service providers. This work aims to explore the question of how leveraging decentralized storage paired with a centralized point of authentication may combat such attacks. A solution, “Bingo”, is presented, which implements browser side clients which store password shares for a centralized proxy server. Bingo is a fully formed system which allows for modern browsers to store and retrieve a dynamic number of anonymized password shares, which are used when authenticating users. Thus, Bingo is the first solution to prove that distributed password storage functions in the context of the modern web. Furthermore, Bingo is evaluated in both simulation and cloud in order to show that it achieves high rates of system liveness despite its dependence on its users being active at given intervals. In addition, a novel simulator is presented which allows future researchers to mock scheduled behavior of online users. This work concludes that with the rise in online activity, decentralization may play a role in increasing data security.

Terahertz Uygulamaları için Grafen Malzemesine Dayalı Mikroşerit Bowtie Anten Tasarımı ve Optimizasyonu

“…In the antenna design, the graphene material could be utilized as an Artificial Magnetic Conductor (AMC), radiating elements, hybrid-metal as a radiating patch in microwave regime, or in the energy harvesting microstrip antenna, underwater communication system, and in the design of photonic device. Also, the graphene can be utilised to develop the meta-material to enhance the antenna performance [13]- [21]. In general, conductive materials lose their conduction properties at very high frequencies, so they sometimes behave like semiconductors or their conductivity decreases significantly.…”
