Security and privacy concerns hinder the adoption of cloud storage and computing in sensitive environments. We present a user-centric privacy preserving cryptographic access control protocol called K2C (Key To Cloud) that enables end-users to securely store, share, and manage their sensitive data in an un trusted cloud storage anonymously. K2C is scalable and supports the lazy revocation. It can be easily implemented on top of existing cloud services and APIs-we analyze its prototype based on Amazon S3 API.
