Abstract: Storing data in the Cloud makes challenging data’s security and users’ privacy. To address these problems cryptographic protocols are usually designed. Cryptographic primitives have to guarantee some security properties such that for instance data and user privacy or authentication. Attribute-Based Signature (ABS) and Attribute-Based Encryption (ABE) are very suitable for storing data on an untrusted remote entity. In this work, we formally analyse the Ruj et al. protocol of cloud storage based on ABS and ABE schemes. Our analysis clarifies several ambiguities in the design of this protocol and reveals an unknown attack against user privacy. We propose a correction, and prove the security of the corrected protocol.
