Deploying quantum light sources on nanosatellites II: lessons and perspectives on CubeSat spacecraft
To enable space-based quantum key distribution proposals the Centre for
Quantum Technologies is developing a source of entangled photons ruggedized to
survive deployment in space and greatly miniaturised so that it conforms to the
strict form factor and power requirements of a 1U CubeSat. The Small Photon
Entangling Quantum System is an integrated instrument where the pump, photon
pair source and detectors are combined within a single optical tray and
electronics package that is no larger than 10 cm x 10 cm x 3 cm. This footprint
enables the instrument to be placed onboard nanosatellites or the CubeLab
structure aboard the International Space Station. We will discuss the
challenges and future prospects of CubeSat-based missions.Comment: Submitted to SPIE Quantum Information Science and Technology. Paper

TCG based approach for secure management of virtualized platforms: state-of-the-art
There is a strong trend shift in the favor of adopting virtualization to get business benefits. The provisioning of virtualized enterprise resources is one kind of many possible scenarios. Where virtualization promises clear advantages it also poses new security challenges which need to be addressed to gain stakeholders confidence in the dynamics of new environment. One important facet of these challenges is establishing 'Trust' which is a basic primitive for any viable business model. The Trusted computing group (TCG) offers technologies and mechanisms required to establish this trust in the target platforms. Moreover, TCG technologies enable protecting of sensitive data in rest and transit. This report explores the applicability of relevant TCG concepts to virtualize enterprise resources securely for provisioning, establish trust in the target platforms and securely manage these virtualized Trusted Platforms
