With the advances in the processing capabilities of wireless devices such as smart phones and laptops, the demand for staying connected to the Internet has steadily increased. This demand is strengthened further by the introduction of Internet connectivity within the airplanes. Mobile IP is one of the protocols that have been proposed to support user/network mobility. Mobile IP introduces new entities...
The electronic mail plays an unavoidable role in the humankind communications. With the great interest for the connection via mobile platforms, and the growing number of vulnerabilities and attacks, it is essential to provide suitable security solutions regarding the limitations of resource restricted platforms. Although some solutions such as PGP and S/MIME are currently available for the secure...
In the recent years, wireless mesh network (WMN) has evolved as a new paradigm for broadband wireless Internet access. The self-configurability, open wireless infrastructure, and different management styles of WMN make them vulnerable to malicious attackers. As a first step to secure WMNs, it is critical to incorporate an authentication mechanism for mesh clients. The existing proposals are primarily...
Most solutions focus on the home network security server management and gateway device certification. It is unrealistic where the most subjects are mobile users who want to control home network devices. Therefore minor and fast certification structures are needed to control other devices with mobile device that has lower computing capacity. To solve the above problems, this paper wants to build safe...
Ubiquitous computing systems typically have lots of security problems in the area of service supply. The service types and levels, the security delegation of services and the identity hiding of principal etc are all these unsolved problems. In this paper, UCSMssp, a new novel ubiquitous computing service model based on SPKI/SDSI and P2P is presented. SPKI-based authorization is exploited in UCSMssp...
In order to encapsulate data and to convey information more efficiently and more security, a draft frame based on active block ciphers for application layer of Internet which could transmit orange data into semantic security and semantic integrity was designed according to scalable purpose. To different network environment, there were different intelligent choices about block cipher algorithms to...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
