Data protection in cloud storage presents significant challenges. Attribute-based encryption (ABE) has been identified as a useful security mechanism for supporting data protection in untrusted environments. ABE enables fine-grained access control over encrypted data and allows individual data owners to define their own data access policy. However, important practical features such as efficient user...
To keep data confidential against unauthorized cloud servers and users, cryptographic access control mechanisms must be adopted. However, user revocation is a challenging issue since it would inevitably require data re-encryption, and may need user secret key updates. Considering the complexity of fine-grained access control policy and the large number of users in cloud, this issue would become extremely...
