Lei Xiangdong,Lei Zhenyang,Long Junic protocol is proposed to formalize the interactions between the users platform and database server. Any existing inference control technique can work with our protocol, for which the security properties are formally proven. Since each user’s platform enforces inference control for its own queries, our solution avoids the bottleneck.

A Privacy-Enhanced Attribute-Based Access Control System our infrastructure enables the deployment of alternative PDPs the service requestor can choose from. We employ a PKI to reflect the sufficient trust relation between the service provider and a potential PDP. Our work is carried out within the European research project Access-eGov that aims at a European-wide e-Government service platform.

gVault: A Gmail Based Cryptographic Network File Systemmodel and key management techniques that ensure data confidentiality and integrity. An initial prototype of gVault is implemented to evaluate the feasibility of such a system. Our experiments indicate that the additional cost of security is negligible in comparison to the cost of data transfer.
