| Abstract | The proliferation of computers, internet and wireless communication capabilities into the physical world has led to ubiquitous availability of computing infrastructure. With the expanding number and type of internet capable devices and the enlarged physical space of distributed and cloud computing, computer systems are evolving into complex and pervasive networks. Amidst the aforesaid rapid growth in technology, secure transmission of data is also equally important. The amount of sensitive information deposited and transmitted over the internet is absolutely critical and needs principles that enforce legal and restricted use and interpretation of data. The data needs to be protected from eavesdroppers and potential attackers who undermine the security processes and perform actions in excess of their permissions. Cryptography algorithms form a central component of the security mechanisms used to safeguard network transmissions and data storage. As the encrypted data security largely depends on the techniques applied to create, manage and distribute the keys, therefore a cryptographic algorithm might be rendered useless due to poor management of the keys. This paper presents a novel computational intelligence based approach for known ciphertext-only cryptanalysis of four-round Data Encryption Standard algorithm. In ciphertext-only attack, the encryption algorithm used and the ciphertext to be decoded are known to cryptanalyst and is termed as the most difficult attack encountered in cryptanalysis. The proposed approach uses Swarm Intelligences to deduce optimum keys according to their fitness values and identifies the best keys through a statistical probability based fitness function. The results suggest that the proposed approach is intelligent in finding missing key bits of the Data Encryption Standard 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.
