Developing a distributed electronic health-record store for India
The DIGHT project is addressing the problem of building a scalable and highly available information store for the Electronic Health Records (EHRs) of the over one billion citizens of India
Open-TEE - An Open Virtual Trusted Execution Environment
Hardware-based Trusted Execution Environments (TEEs) are widely deployed in
mobile devices. Yet their use has been limited primarily to applications
developed by the device vendors. Recent standardization of TEE interfaces by
GlobalPlatform (GP) promises to partially address this problem by enabling
GP-compliant trusted applications to run on TEEs from different vendors.
Nevertheless ordinary developers wishing to develop trusted applications face
significant challenges. Access to hardware TEE interfaces are difficult to
obtain without support from vendors. Tools and software needed to develop and
debug trusted applications may be expensive or non-existent.
In this paper, we describe Open-TEE, a virtual, hardware-independent TEE
implemented in software. Open-TEE conforms to GP specifications. It allows
developers to develop and debug trusted applications with the same tools they
use for developing software in general. Once a trusted application is fully
debugged, it can be compiled for any actual hardware TEE. Through performance
measurements and a user study we demonstrate that Open-TEE is efficient and
easy to use. We have made Open- TEE freely available as open source.Comment: Author's version of article to appear in 14th IEEE International

A survey on online monitoring approaches of computer-based systems
This report surveys forms of online data collection that are in current use (as well as being the subject of research to adapt them to changing technology and demands), and can be used as inputs to assessment of dependability and resilience, although they are not primarily meant for this use
