NLHB : A Non-Linear Hopper Blum Protocol (2010)
Madhavan, Mukundan, Thangaraj, Andrew, Sankarasubramaniam, Yogesh, Viswanathan, Kapali
In this paper, we propose a light-weight provably-secure authentication protocol called the NLHB protocol, which is a variant of the HB protocol. The HB protocol uses the complexity of decoding...
Denial of Service Issues in Voice Over IP Networks (2008)
Jason Reid, Andrew Clark, Juan M González Nieto, Jason Smith, Kapali Viswanathan
Abstract: In this paper we investigate denial of service (DoS) vulnerabilities in Voice over IP (VoIP) systems, focusing on the ITU-T H.323 family of protocols. We provide a simple characterisation...
Key Recovery System for the Commercial Environment (2007)
Juan Manuel González Nieto, Juan Manuel, Kapali Viswanathan, Ed Dawson, Colin Boyd
. We propose an ecient, scalable, exible key recovery solution for use in commercial environments. Our scheme takes a new approach in the design of key recovery systems, called hybrid key escrow. We...
Secure Selection Protocols (2007)
Kapali Viswanathan, Colin Boyd, Ed Dawson
The process of selection is omnipresent in the real world and modeling this process as a cryptologic protocol will enable cross use of techniques among similar protocol applications, which will...
Strong Binding for Software Key Escrow (2007)
Kapali Viswanathan, Colin Boyd, Ed Dawson
Research for software based key escrow systems (KES) presents interesting problems. Advantages of software based KES over hardware based systems are openness, user acceptance, examinability,...

A Three Phased Schema for Sealed Bid Auction System Design (2000)
Kapali Viswanathan, Colin Boyd, Ed Dawson
Auction systems allow many entities, each possessing a unique secret value, to interact in order to reveal the winning value from the set of secret values, based on the rules of interaction. A...
Signature Scheme for Controlled Environments (1999)
Kapali Viswanathan, Colin Boyd, Ed Dawson
We propose a signature system that will be very useful for controlled environments, like corporate networks, where regulation of signatures generated using the certified public/private key pairs is...
Publicly Verifiable Key Escrow with Limited Time Span (1999)
Kapali Viswanathan, Colin Boyd, Ed Dawson
. Limiting escrow activity in time has been an important requirement for key escrow systems. Recently two protocols were proposed for limited time span key escrow and contract bidding. We investigate...
