Distributed denial of service (DDoS) attacks still remains as one of the largest concerns for online businesses. Although an HTTPS compatible scheme is necessary for many online services, several previously proposed defense schemes fail to combine both HTTPS compatibility with practicality. In this paper, a novel defense architecture that blocks malicious traffic far from the protected servers is...
Many e-commerce applications are prevalent in today's world. New features and enhanced security, both are required for successful launch and deployment of e-commerce applications. In this paper, we focus on a generic e-commerce architecture, called eTRON which incorporates - at its nucleus - the tamper-resistant eTRON chip, equipped with functions for mutual authentication, secure communication, and...
As we know, the communication networks were first designed for voice communication purposes. Further developments within the communication networks made it possible to send or transmit data as well. When the public network is used as a bearer for data which need high security, e.g. payment, shopping, police telecommunication or mobile betting, there is a possibility that an attacker might capture...

It has been a fundamental but challenging problem to preserve the privacy of the two negotiation parties during the period...
Many of the current mobile commerce applications and services suffer from several security leakage problems. A consequent exploitation of biometric identifiers (such as human voice) integrated into multimedia processing techniques may turn out to be a viable solution to these problems. In this paper we demonstrate how digital watermarking techniques and authentication protocols can efficiently be...
