Project CloudUTrust - Symmetric Searchable Encryption and Attribute-Based Encryption for cloud security and privacy

 

Cloud storage security is a core aspect that businesses and end-users consider before moving private data to the cloud. Data encryption is a cornerstone of cloud storage security. The research community presented novel approaches based either on the promising concept of Symmetric Searchable Encryption (SSE) or on the well-studied field of Attribute-Based Encryption (ABE). In the case of SSE, researchers work on protocols where user data is protected from both internal and external attacks; however, user revocation remains unaddressed. In the case of ABE, existing approaches successfully address the problem of revocation; however, they are inefficient since ABE schemes produce long ciphertexts and the decryption process requires lot of computational resources.

The core idea of the project is to combine ABE schemes with SSE to provide cloud-based services that ensure the protection of data confidentiality and user privacy, while maintaining the fundamental benefits of cloud computing (e.g. easiness of sharing files between multiple users).

The following partners are currently part of the feasibility study consortium:

  • RISE SICS Security Lab, Sweden;
  • Cyber Security Group (CSec), University of Westminster, London, U.K.;
  • UBITECH, Athens, Greece.

In this feasibility study we will bring together a team of experienced partners that will contribute their experise to the successful implementation of the project objectives. This will help achieve the main goal of the project: design and implement secure and privacy-preserving cloud-based services using the latest advancements in cryptography.
