| Abstract | Based on generalized chaos synchronization theorems for bidirectional discrete system, we construct a Hénon area-preserving quadratic system, and design a new 3-dimensional chaotic system called generalized discrete predator-prey system. Furthermore, a new encryption algorithm based on composite two new discrete chaotic systems for sound communication is proposed. This encryption algorithm has 9 keys, and the secure key space is larger than $2^{225}.$ At first, the algorithm uses the key stream generated by discrete chaotic systems to mask secrete image. Second, it uses the least significant bit (LSB) embeddinf method to embed the masked message into audio signals. Our method can be used for steganography in the Internet audio signal communications. The analysis of the key space, sensitivity of key parameters, and correlation of encrypted signals imply that our encryption algorithm has good security. |

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.
