	1	Generic user revocation systems for attribute-based encryption in cloud storage显示文摘Cloud-based storage is a service model for businesses and individual users that involves paid or free storage resources. This service model enables on-demand storage capacity and management to users anywhere via the Internet. Because most cloud storage is provided by third-party service providers, the trust required for the cloud storage providers and the shared multi-tenant environment present special challenges for data protection and access control. Attribute-based encryption(ABE) not only protects data secrecy, but also has ciphertexts or decryption keys associated with fine-grained access policies that are automatically enforced during the decryption process. This enforcement puts data access under control at each data item level. However, ABE schemes have practical limitations on dynamic user revocation. In this paper, we propose two generic user revocation systems for ABE with user privacy protection, user revocation via ciphertext re-encryption(UR-CRE) and user revocation via cloud storage providers(UR-CSP), which work with any type of ABE scheme to dynamically revoke users.

	2	Generic attribute revocation systems for attribute-based encryption in cloud storage显示文摘Attribute-based encryption(ABE) has been a preferred encryption technology to solve the problems of data protection and access control, especially when the cloud storage is provided by third-party service providers.ABE can put data access under control at each data item level. However, ABE schemes have practical limitations on dynamic attribute revocation. We propose a generic attribute revocation system for ABE with user privacy protection. The attribute revocation ABE(AR-ABE) system can work with any type of ABE scheme to dynamically revoke any number of attributes.
