DAC-MACS: Effective data access control for multi-authority cloud storage systems
Ciphertext-Policy Attribute-based Encryption (CP-ABE) is a promising technique for access control of encrypted data, which requires a trusted authority to manage all the attributes and distributes keys in the system. In multi-authority cloud storage systems, the users’ attributes come from different domains each of which is managed by a different authority. However, existing CP-ABE schemes cannot be directly applied to data access control for multi-authority cloud storage systems, due to the inefficiency of decryption and revocation. In this chapter, we propose DAC-MACS (Data Access Control for Multi-Authority Cloud Storage), an effective and secure data access control scheme with efficient decryption and revocation.
