| Abstract | RC4 is one of the most widely used stream cipher. It is fairly simple and efficient, and is used, among other things, in WEP, TKIP and SSL/TLS protocols. Fluhrer, Mantin and Shamir show that RC4 is completely insecure in the WEP mode of operation, and most of the discovered weaknesses are related to the key-scheduling algorithm (KSA) part of RC4. Crainicu and Boian propose a new variant of key-scheduling algoritm, called KSAm, whose primary goal is to address the Fluhrer-Mantin-Shamir (FMS) weakness of WEP-like cryptosystems, where IV (initialization vector) precedes the secret key. Cryptanalysis of KSAm reveals that the FMS IV weakness is removed by destroying the FMS resolved condition. This paper summarizes the previous security analyses of KSAm, examines KSAm in the WEP mode of operation, where IV follows the secret key, and discusses new security aspects like the effect of other FMS weak keys and Roos weak keys on KSAm and the randomness of the state tablepsila first entries after KSAm completion. |

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.
