| Abstract | Gossamer protocol has been recently published to achieve mutual authentication in low-cost RFID tags. This protocol is considered to fall in ultra-lightweight class as it incorporates simple and low cost operations. Most of the earlier proposals in this class were exposed soon after their publication. Common weaknesses included use of Triangular functions and improper use of logic operators. Gossamer protocol used two non-triangular functions a) ROTbits and b) MIXbits. These functions provide confusion and diffusion properties and are implemented as cheaper operations. Thus, this protocol can be used for EPCglobal Class-1 Generation-2 standard (considered as universal standard for low-cost tags). This protocol is able to overcome existing weaknesses and is considered to be more attractive for low-capability devices as compared to earlier protocols of this class. In this paper, we analyze the security features provided by Gossamer protocol. The vulnerabilities discovered during this analysis reveal that different attacks including denial of service, memory and computation exhaustive, de-synchronization, replay, attack on data integrity and IDS (index pseudonym) collision are possible. As a consequence, we propose a new mutual authentication protocol keeping in mind the constraints and making use of the existing operations without addition of any expensive one. The analysis of the proposed protocol shows that it is resistant to all the attacks possible in case of Gossamer protocol. A comparative security analysis shows that proposed protocol provides better security features with a small compromise of communication overheads. Two additional public messages are exchanged between the reader and the tag to address the vulnerabilities present in Gossamer protocol. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
