| Abstract | At Eurocrypt'02, Horwitz and Lynn first introduced the concept of HIBS. Till now, many HIBS schemes have been proposed. Recently (2011), Yang et al.'s proposed a hierarchical identity based signature (HIBS) scheme based on computational Diffie-Hellman (CDH) assumption in the standard model. They claimed that their scheme has more secure and more efficient than the existing HIBS schemes. However, we give an attack to their scheme to show that their scheme is insecure and an attacker can forge private key for any identity. And we also propose an improvement method. |

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.
