March 2018. It has been three years since we officially launched the TREDISEC Project.
In our backpack, more than 25 security primitives, 9 recipes and a Framework to support the development, integration, use and adoption of these solutions by different stakeholders of the Cloud Security market.
PerfectDedup is a new scheme that enables the cloud to securely deduplicate redundant data when it is encrypted. PerfectDedup relies on the use of different encryption techniques based on the popularity of the data: Popular data are protected under convergent encryption and can therefore be deduplicated; unpopular data segments which are likely to remain unique are protected under semantically-secure symmetric encryption.
MUSE is a searchable encryption scheme that enables cloud users to upload their encrypted data and authorize other users to perform lookup queries over these data. The main privacy guarantee that MUSE offers is that it does not disclose the content of the data and the queries to the cloud.
Container Isolation component preserves confidentiality of sensitive data in a containerized virtual environment. By exploiting Docker’s layered filesystem users can securely manipulate images throughout their life cycle. The component can secure both data on disk, by encrypting/decrypting on the fly, and data migration by enhancing the image distribution process.
ML-PoR is a proof of retrievability scheme that enables a cloud user to verify the correct storage of her outsourced data while allowing the cloud to perform secure deduplication whenever there is redundancy.
Only four months left to finish TREDISEC!
It has been a long way, but the time has come. We are in the final countdown and we have obtained awesome results along this tough but exciting period. So let's start showing off!
In order to do that, we have chosen the conference ISSE: The future of Digital Security & Trust. The TREDISEC workshop took place in the morning of the second day of the conference and was titled "How to reconcile cloud efficiency with security & privacy". This is our mantra and we wanted to get across the message that TREDISEC provides the necessary means to achieve it.
Proof of Ownership (PoW) is a cryptographic protocol that regulates the interactions between a prover and a verifier. The protocol is usually executed in the context of a storage outsourcing scenario, where the prover is the client and the verifier is the (storage) service provider.
