Grid Security and Integration with Minimal Performance Degradation
Sugata Sanyal, Rangarajan A. Vasudevan, Ajith Abraham +1
Computational grids are believed to be the ultimate framework to meet the growing computational needs of the scientific community. Here, the processing power of geographically dist…
CompChall: Addressing Password Guessing Attacks
Vipul Goyal, Virendra Kumar, Mayank Singh +2
Even though passwords are the most convenient means of authentication, they bring along themselves the threat of dictionary attacks. Dictionary attacks may be of two kinds: online…
A Multi-Factor Security Protocol for Wireless Payment - Secure Web Authentication using Mobile Devices
Ayu Tiwari, Sudip Sanyal, Ajith Abraham +2
Previous Web access authentication systems often use either the Web or the Mobile channel individually to confirm the claimed identity of the remote user. This paper proposes a new…
An LSB Data Hiding Technique Using Prime Numbers
Sandipan Dey, Ajith Abraham, Sugata Sanyal
In this paper, a novel data hiding technique is proposed, as an improvement over the Fibonacci LSB data-hiding technique proposed by Battisti et al. First we mathematically model a…
An LSB Data Hiding Technique Using Natural Numbers
Sandipan Dey, Ajith Abraham, Sugata Sanyal
In this paper, a novel data hiding technique is proposed, as an improvement over the Fibonacci LSB data-hiding technique proposed by Battisti et al,based on decomposition of a numb…
A Novel Scheme for Secured Data Transfer Over Computer Networks
Rangarajan Athi Vasudevan, Ajith Abraham, Sugata Sanyal
This paper presents a novel encryption-less algorithm to enhance security in transmission of data in networks. The algorithm uses an intuitively simple idea of a "jigsaw puzzle" to…
