| Abstract | In this paper we investigate potential vulnerabilities in the implementation of encryption processes within the EEA2 algorithm of Long-Term Evolution (LTE), and we propose an enhancement for the security features in LTE. We show that during the encryption process in EEA2, a leakage of 128 bits of plain text and its corresponding cipher text in a PDU, could potentially allow an intruder to recover the key, hence the entire original plain text could be compromised. We propose a solution by adding a matrix block to the encryption process of the cipher text. The proposed encryption process uses a random set of numbers in the form of a matrix, which is used with the cipher text in order to obtain an enriched block of ciphered data. We have implemented the algorithm in Matlab, and successfully tested several use cases to produce an enriched block of encrypted data, which is then decrypted to obtain the original text. We also show by simulation that enriching the data using this system will improve the encryption process; however, the cost is increasing the complexity of the algorithm. |

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.
