| Abstract | We propose a digital cash system suitable for low value transactions and a secure SMS protocol based on EC-MQV key agreement protocol and AES encryption algorithm to operate the proposed digital cash system. The key security aspects of the protocol are resilience to SIM cloning, SIM swapping attacks and possible message tampering using a GSM ghost base station. It further provides for 2 factor authentication by using IMSI number as proof of “what you have?” and a user provided password as proof of “what you know?”. The total cost of executing a financial transaction is 2 SMS messages. We use the proposed protocol to implement a digital cash system. We strongly believe such a low cost secure digital cash system can be a boon to extend financial services to people who are left out of regular banking services due to the high cost of providing the same through existing banking and payment solutions. The low communication cost associated with each financial transaction makes it financially viable for handling low value transactions. The proposed protocol was implemented for both android and J2ME mobile phones with an easy to use interface wherein any individual with number literacy can operate. This makes it easy to deploy in less developed economies where literacy is often a challenge. |

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.
