A secure Web-based watermarking scheme is proposed to allow the publisher or information provider to mark their copyrighted materials and identify an illegal distributor through the World Wide Web (WWW). In our proposed scheme, multi-watermark techniques and double encryption method is applied to make the scheme available in e-transaction and secure against collusion attacks even if the third party...
According the complex deployment region and the various demands in wind tunnel, a novel disruption-tolerant wireless sensor networks (DT-WSN) architecture is developed in this paper. Mobile routers (rovers) are introduced to collect and relay sensing data from static nodes. We present a stochastic analytical framework to study the performance of the network model. The epidemic algorithms based system...
The formal description of authentication protocol and its security analysis is one of the important issues in the protocol analysis. In order to solve the problem in the formal description of cryptographic protocol, a method based on directed graph is presented to formally depict the authentication protocol specification. Meanwhile, a converse-searching algorithm based on directed graph is also presented...
