title = "Secure data sharing with fast access revocation through untrusted clouds",
abstract = "With the introduction of recent regulations concerning data privacy, encrypting data before uploading it to a public cloud becomes a widespread approach. Such processing reinforces data confidentiality but raises a challenge for efficient access revocation. In this paper, we introduce a conceptual multi-cloud architecture supporting a fast access revocation of outsourced data. The proposed data processing method is based on a combination of encryption, all-or-nothing transformation, and data dispersal. Theoretical and experimental evaluations show that our technique is the fastest among the state-of-the- art solutions.",
