Cloud Computing is an emerging technology that is attracting increased attention as a high-performance and low-cost solution to process arbitrarily huge data and share them among different users and organizations. Nonetheless, this technology rises new questions concerning security and privacy, especially when working with highly confidential data. Existing solutions offering end-to-end security are of no help since the stored data is only encrypted during its transport.
Therefore, a message-level security must at least be applied to protect those data during and after the storing process. This security project investigates a novel solution for secure and highly scalable data storage in the cloud. It allows each client to encrypt outgoing data on his device and share it among a defined user group while using a seamless service provision. The property of Sec2 solution is that users keep full control over their data and no changes on the existing infrastructure of cloud storage services are needed.
