S -Solutions

The goal of this project area is to provide cryptography-based security solutions that match all the necessary functional requirements to establish trust in new and next generation computing environments. Such solutions have been and will be indispensable to establish trust in the identities and properties of actors, in the soundness of their devices, and in the proper functioning and privacy-friendliness of services.

S6 - Long-Term Secure Archiving

This project develops techniques that allow for an efficient and trustworthy archiving system providing long-term confidentiality, integrity, authenticity, nonrepudiation and datedness protection, and supports computations on archived data. The project first develops the necessary individual components and then combines them into an overall long-term archive solution. Our overall solution will be designed within a new framework that combines cryptographic security and computational trust models.
