摘要:Cloud computing provides service models to both businesses and individual users for either paid or free computing resources. Those service models enable on-demand computing capacity, and management to users anywhere via the Internet. The trust required for the public cloud service providers (CSPs) and the shared multi-tenant environment present special challenges for data protection and access control. Attribute-Based Signature (ABS) schemes not only protect user secrecy, but also have fine-grain access policies that are automatically enforced during the user identification and authorization process. ABS can therefore be used to facilitate anonymous access control and allow users to sign messages without disclosing their identities. However, access control approaches associated with existing ABS schemes also have practical limitations concerning dynamic user and attribute revocation, in particular anonymous user revocation. In this talk, we will discuss how to adopt existing ABSs and provide them with more flexible user and attribute management capability.
