HPI-Kolloquium: "Data Protection in Resource-Constrained Computing Systems"

Anne Kayem, PhD

17. Mai 2018

Abstract
Resource-constrained computing is a variant of distributed computing, in which computations are conducted using low-powered, low-processing, and memory-limited components. Systems based on this concept are well suited to scenarios where access to standard technology is impeded by infrastructural and economic factors. Application examples emerge in health information systems, environmental monitoring, and in cyber-physical-systems such as smart microgrids. The focus of this talk will be on data protection in resource constrained computing systems in which resources are user-contributed. Since the management of such a system is by necessity distributed, providing firm guarantees of data protection to users, is important in ensuring stability. The reason for this is that system stability is contingent on user participation. Therefore, loss of trust in the reliability of the system can result in user withdrawals and a breakdown of the system. I begin by considering models which are dependent on high-processing computing components such as cloud computing systems. Then, progressively transition towards models in which the system operates autono-mously based solely on user-contributed resources. To demonstrate feasibility, I will describe re-sults from prototype implementations.

Short CV
