Whitepaper: Improving the Usability of Web Browser Security

by University of PittsburghJan 01, 2008

SecureWeb sites use HTTPS, which layers HTTP over SSL or its standard equivalent, TLS. Existing Web browsers handle security errors in a manner that often confuses users. In particular, when a user visits a secure site whose certificate the browser cannot verify, the browser typically allows the user to view and install the certificate and connect to the site despite the verification failure. However, few users understand the risk of man-in-the-middle attacks and the principles behind certificate-based authentication. This paper proposes Context-Sensitive Certificate Verification, whereby the browser interrogates the user about the context in which a certificate verification error occurs.

Whitepaper: Efficient Data Dissemination to Mobile Clients in E-Commerce Applications

by University of PittsburghJan 01, 2008

In mobile environments, data dissemination is more challenging due to the limited, wireless bandwidth available for communication, frequent disconnections and low power withholding capacity of mobile devices. Mobile commerce is the next growing area in electronic commerce and mobile computing. These are sophisticated, data intensive mobile applications whose success strongly depends on the efficiency by which data are disseminated to a large number of mobile users. This paper proposes a new broadcast indexing scheme, termed ?Constant-Size I-node Distributed Indexing? (CI) that offers more energy savings in practical applications.
