S6 – Long-Term Secure Archiving

Download

The project develops techniques that allow for long-term secure storage of digital data. It improves efficiency and scalability of the long-term secure archiving solution LINCOS developed in CROSSING I. It also enables long-term secure distributed data management in LINCOS, notably by developing new ORAM solutions. Finally, the project develops techniques that allow complex and verifiable computations on long-term protected data in LINCOS.
