Fluorescent Multilayer Disc (FMD)

ABSTRACT

Compact discs were a revolutionary product at its time and influenced many spheres of human activity. People started recording music of high quality, which didn’t get worse with the time as it happens to be on tape. As soon as CDs appeared in computer industry they immediately became an undoubted helper both for users and for programmers. The latter were able to increase volume of their program products by adding video and audio elements etc. Later discs were used for digital video (VideoCD).

But technologies are progressing. Data are growing faster and faster. A usual CD is far not enough (640 MBytes). So, there appeared DVD technology. Of course we are happy with those 17 GBytes that can be kept on one DVD disc, but this is a limiting point. So we need a completely new method of storing information on portable data medium. And at last, the company Constellation 3D demonstrates a new format: FMD (Fluorescent Multilayer Disk), which can provide us with a staggering 140 GB of storage space seems to be an enticing solution for the storage-hungry masses.

Embedded Systems Security

ABSTRACT

The paper discusses the hardware and software security requirements in an embedded device that are involved in the transfer of secure digital data. The paper gives an overview on the security processes like encryption/decryption, key agreement, digital signatures and digital certificates that are used to achieve data protection during data transfer. The paper also discusses the security requirements in the device to prevent possible physical attacks to expose the secure data such as secret keys from the device. The paper also briefs on the security enforced in a device by the use of proprietary security technology and also discusses the security measures taken during the production of the device.

Security Challenge and Defense in VoIP Infrastructures

ABSTRACT

Voice over Internet Protocol (VoIP) has become a popular alternative to traditional public-switched telephone network (PSTN) networks that provides advantages of low cost and flexible advanced “digital” features. The flexibility of the VoIP system and the convergence of voice and data networks brings with it additional security risks. These are in addition to the common security concerns faced by the underlying IP data network facilities that a VoIP system relies on. The result being that the VoIP network further complicates the security assurance mission faced by enterprises employing this technology. It is time to document various security issues that a VoIP infrastructure may face and analyze the challenges and solutions that may guide future research and development efforts. In this paper, we examine and investigate the concerns and requirements of VoIP security. After a thorough review of security issues and defense mechanisms, we focus on attacks and countermeasures unique to VoIP systems that are essential for current and future VoIP implantations. Then, we analyze two popular industry best practices for securing VoIP networks and conclude this paper with further discussion on future research directions. This paper aims to direct future research efforts and to offer helpful guidelines for practitioners.

Parasitic Computing

ABSTRACT


“PARASITE” as the word suggests is an entity that resides on another entity exploiting the resources of the latter. The term “PARASITIC COMPUTING” refers to the technique of using the resources of one computer by another computer without the knowledge of the former. Distributed computing networks turn home users’ computers into part of a virtual supercomputer that can perform time-intensive operations. This seminar provides an insight into the details of how parasitic computing uses the computation power of the computers connected to the internet in solving complex mathematical problems. This technique was developed by the scientist at the Notre Dame University, Indiana (USA). According to the scientists, the transmission control protocol (TCP), could be used to solve a piece of a mathematical problem whose answer could then be relayed back to the original user. The implementation is discussed with the NP-Complete problem as example. Unlike hackers who exploit flaws to gain direct access to machines, the Notre Dame computer scientists created a virtual computer by using the fundamental components of distributed computing.

Windows DNA

ABSTRACT


Microsoft Windows Distributed interNet Applications Architecture (Windows DNA) is the application development model for the Windows platform. Windows DNA specifies how to: develop robust, scalable, distributed applications using the Windows platform; extend existing data and external applications to support the Internet; and support a wide range of client devices maximizing the reach of an application. Developers are free from the burden of building or assembling the required infrastructure for distributed applications and can focus on delivering business solutions.

Windows DNA addresses requirements at all tiers of modern distributed applications: presentation, business logic, and data. Like the familiar PC environment, Windows DNA enables developers to build tightly integrated applications by accessing a rich set of application services in the Windows platform using a wide range of familiar tools. These services are exposed in a unified way through the Component Object Model (COM). Windows DNA provides customers with a roadmap for creating successful solutions that build on their existing computing investments and will take them into the future. Using Windows DNA, any developer will be able to build or extend existing applications to combine the power and richness of the PC, the robustness of client/server computing, and the universal reach and global communications capabilities of the Internet.
