AIT’s main goal during the second project year was the implementation and development of high-performance implementations of secret sharing and erasure coding schemes, based on the analysis and requirements identified during the requirement elicitation phase in the first project year, as well as customer and stakeholder feedback. As a result, the erasure-coding implementations started in M01-M12 were further optimized for x86 architectures, but also perform favorably on other architectures. Given the considered use case scenarios, recommending computational secret sharing as a secure variant, also a first design for a high-speed block-cipher for disk encryption scenarios was developed, solving efficiency and security drawbacks of existing solutions.

Furthermore, the source code was polished and documented, and then released under a GPL3 license to partner LINBIT, who will further pursue their efforts to integrate the implementations into the default Linux kernel, thereby becoming available to millions of users “out of the box”.

Finally, AIT put a focus on potential exploitation scenarios also beyond DRBD4Cloud and the joint commercialization with LINBIT, resulting in strengthened collaborations with two Austrian SMEs, which will integrated project results into their service offers.

Overall, we thus consider the goals of M13-M24, and therefore also of the entire project, as successfully achieved within time and budget. The goals and ambitions of the project are still relevant, and were further underpinned by an increasing demand for efficient and secure cloud storage solutions over the last year
