| Abstract | The advanced encryption standard (AES) is the most encryption algorithm used around the world. This fact made it coveted by several cryptanalysis attacks. Some of them succeed to reveal certain weakness, due to its static parameters known by the public mass. The substitution box (S-Box) is among the most sensitive parameters of this standard, which plays a crucial role in the protection against these attacks. In this study, a new version of AES is introduced, which uses a set of AES-like S-Boxes instead of the original one. These S-Boxes, generated from different irreducible polynomials, are dynamically chosen, depending on the encryption key. This introduction is conducted by the design and the implementation of a new block cipher version of AES, based on a key dependent S-Box cube. Where a cube of six interchangeable S-Boxes key-dependently generated is constructed. This cube determines the active S-Box for a given round, through its random rotations guided by the round key. Furthermore, the improvement of the cryptographic robustness, provided by this method is demonstrated. This is accomplished through a comparison with the original AES, in terms of statistical and cryptographic randomness properties. |

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.
