Abstract Stronger Password Authentication Using Browser Extensions ∗

by Blake Ross, Dan Boneh
"... We describe a browser extension, PwdHash, that transparently produces a different password for each site, improving web password security and defending against password phishing and other attacks. Since the browser extension applies a cryptographic hash function to a combination of the plaintext pas ..."

password entered by the user, data associated with the web site, and (optionally) a private salt stored on the client machine, theft of the password received at one site will not yield a password that is useful at another site. While the scheme requires no changes on the server side, implementing

Unreliable Network Re-Authentication Protocol Based on Hybrid Key Using CSP Approach

by Sureswaran Ramadass, Rahmat Budiarto, Ho Cheah Luan , 2007
"... Network security is becoming increasingly vital in today’s fast growing mobile computing environment. Due to constraints in device size and portability, limited processing power, small disk capacity, intermittent network disconnections and frequent switching between network access points have been o ..."

In this study, improved reauthentication scheme have been focused on, by performing comprehensive analysis to propose an enhanced authentication protocol which supports fast re-authentication for connection or disconnection of client-server system and other possibility of enhancement in terms

A Novel Cryptographic Key Distribution Scheme for Cloud Platforms

by Satpreet Kaur, Cgc Landran Mohali, Mandeep Singh, Cgc Landran Mohali
"... The problem of secure data transmission on cloud environments is addressed in the proposed security model. The data security is quite important on cloud environments because they belongs the users. The security layer is defined or implemented between the cloud user and server end to ensure the secur ..."

will develop the proposed scheme named EMCKS for corporate key management technique adaptable for the clouds by making it efficient and quicker. In addition, it also has to be improved to work with Cloud server and client nodes, which enforces the proposed scheme to create a secure environment based cloud

Seamless Handover in WLAN and Cellular Networks through Intelligent Agents

by Li-der Chou, Wei-cheng Lai, Chen-han Lin, Yen-cheng Lin, Chin-min Huang
"... This paper presents an efficient method to support preauthentication for seamless handover and implement key distribution with EAP-SIM based AAA protocols for WLAN. Our goal is minimizing the probability of SIP calls blocking resulting from the handoff delay. The intelligent agents may play differen ..."

The benefit of server intelligent agents maintaining user’s profile is user intelligent agents do

22.10.2009 Implementation of a Peer-to-Peer Multiplayer Game with Realtime Requirements

by Gutachten Alej, Ro Buchmann
"... Massively multiplayer online games (MMOGs) have become increasingly popular in the recent years, particularly in the form of online role-playing games (MMORPGs). These games support up to several ten thousand players interacting in a virtual game world. The current commercially successful games are ..."

For MMOGs with higher realtime requirements and/or a smaller number of customers willing to pay, peer-to-peer networking seems to be a

Modelling and Simulation of a Biometric Identity- Based Cryptography

by Dania Aljeaid, Xiaoqi Ma, Caroline Langensiepen
"... Abstract—Government information is a vital asset that must be kept in a trusted environment and efficiently managed by authorised parties. Even though e-Government provides a number of advantages, it also introduces a range of new security risks. Sharing confidential and top-secret information in a ..."

we showed how Petri Nets could be used to simulate the communication patterns between the server and client as well as to validate the protocol functionality. Keywords—e-Government; identity-based cryptosystem; biometrics; mutual authentication; finite-state machine; Petri net. I.

Multi-file proofs of retrievability for cloud storage auditing

by Bin Wang A, Xiaojing Hong B
"... Abstract: Cloud storage allows clients to store a large amount of data with the help of storage service providers (SSPs). Proof-of-retrievability(POR) protocols allow one server to prove to a verifier the availability of data stored by some client. Shacham et al. presented POR protocols based on hom ..."
