prevention of trespasser accessing in networks using Ticket Granting Service
2013Co-Authors: C Jayalakshmi, Senthil A KumarAbstract:This paper addresses the problem of protecting the system from non trusted users access the policy share. Web site administrators routinely rely on IP-address blocking for disabling access to misbehaving users, but blocking IP addresses is not practical if the abuser routes through an anonym zing network. As a result, administrators block all known exit nodes of anonym zing networks, denying anonymous access to misbehaving and behaving users alike. To address this problem, we present Nymble, a system in which servers can “blacklist” misbehaving users, thereby blocking users without compromising their anonymity. The interactive counterparts of group signatures are identity escrow schemes or group identification scheme with revocable anonymity. This work introduces a new provably secure group signature and a companion identity escrow scheme that are significantly more efficient than the state of the art. In its interactive, identity escrow form, our scheme is proven secure and coalition-resistant under the strong RSA and the decisional Diffie-Hellman assumptions.

DDAS using Kerberos with Adaptive Huffman Coding to enhance data retrieval speed and security
2015 International Conference on Pervasive Computing (ICPC), 2015Co-Authors: Suraj Gulhane, Sonali BodkheAbstract:The increasing fad of deploying application over the web and store as well as retrieve database to/from particular server. As data stored in distributed manner so scalability, flexibility, reliability and security are important aspects need to be considered while established data management system. There are several systems for database management. After reviewing Distributed data aggregation Service(DDAS) system which is relying on Blobseer it found that it provide a high level performance in aspects such as data storage as a Blob (Binary large objects) and data aggregation. For complicated analysis and instinctive mining of scientific data, Blobseer serve as a repository backend. WS-Aggregation is the another framework which is viewed as a web Services but it is actually carried out aggregation of data. In this framework for executing multi-site queries a single-site interface is provided to the clients. Simple storage Service (S3) is another type of storage utility. This S3 system provides an anytime available and low cost Service. Kerberos is a method which provides a secure authentication as only authorized clients are able to access distributed database. Kerberos consist of four steps i.e. Authentication Key exchange, Ticket Granting Service Key exchange, Client/Server Service exchange and Build secure communication. Adaptive Huffman method to writing (also referred to as Dynamic Huffman method) is associate accommodative committal to writing technique basic of Huffman coding. It permits compression as well as decompression of data and also permits building the code because the symbols square measure is being transmitted, having no initial information of supply distribution, that enables one-pass cryptography and adaptation to dynamical conditions in data.

XKDCP, the Inter-KDC protocol for cross-realm operations in Kerberos.
2006Co-Authors: Saber ZrelliAbstract:This memo proposes protocol extensions to the Kerberos protocol specification. The extension (hereafter called XKDCP) offers a new cross-realm protocol for Kerberos. The XKDCP extension defines a protocol between Kerberos Key Distribution Centers (KDCs) that allows a KDC to build credentials even when the client or the requested Service is not registered in the KDC's database (but registered in another KDC's database). The XKDCP extension defines two protocols: XTGSP (Inter Ticket Granting Service Protocol) and XASP (Inter Authentication Service Protocol). The XTGSP protocol can be used in remote access scenarios to allow the local KDC to deliver credentials for Services located in remote realms. On the other hand, the XASP protocol can be used in case of cross-realm roaming scenarios to allow the visited KDC to deliver credentials for roaming users.
