| Abstract | 3G/4G cellular networks adopt usage-based charging. Mobile users are billed based on the traffic volume when accessing data service. In this work, we assess both this metered accounting architecture and application-specific charging policies by operators from the security perspective. We have identified loopholes in both, and discovered two effective attacks exploiting the loopholes. The "toll-free-data-access-attack" enables the attacker to access any data service for free. The "stealth-spam-attack" incurs any large traffic volume to the victim, while the victim may not be even aware of such spam traffic.Our experiments on two operational 3G networks have confirmed the feasibility and simplicity of such attacks. We also propose defense remedies. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
