Performance Analysis of a Linux-based FTP Server

Linux over the past couple of years has matured to the point where it has been accepted as a viable platform for server applications. This transformation is due to its stability and support provided by a few companies. Currently it is being used by Internet Service Providers. Linux will be accepted for more serious applications only if it can handle heavy loads. This thesis analyzes the performance of Linux in one such application, the FTP server. Several experiments were conducted to d ....etc

ABSTRACT
File Transfer Protocol (FTP) is a standard network protocol used to copy a file from one host to another over a TCP/IP-based network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server. FTP users may authenticate themselves using a clear-text sign-in protocol but can connect anonym ....etc

Abstract; Nowadays, most cellular phones are used beyond voice communication. Although the processing power of cellular phones is sufficient for most data applications, it is difficult to play video and audio contents in software because of their computational complexity and lack of basic tools for multimedia processing, so software-based multimedia processing on cellular phones is a challenging issue. Several transcoding methods are introduced to address this issue, but they are mainly of the DCT-domain conversion. Hence, they are only appli ....etc

Abstract—Recently, Bertino, Shang and Wagstaff proposed a time-bound hierarchical key management scheme for secure broadcasting. Their scheme is built on elliptic curve cryptography and implemented with tamper-resistant devices. In this paper, we present two collusion attacks on Bertino-Shang-Wagstaff scheme. The first attack does not need to compromise any decryption device, while the second attack requires to compromise single decryption device only. Both attacks are feasible and effective.

FTP server bounce attack


The motive
==========
You are a user on foreign.fr, IP address F.F.F.F, and want to retrieve
cryptographic source code from crypto.com in the US. The FTP server at
crypto.com is set up to allow your connection, but deny access to the crypto
sources because your source IP address is that of a non-US site . In any case, you
cannot directly retrieve what you want from ....etc

1. Explain the salient features of e-mail? Explain its working with the help of an example.

Soln: - Electronic mail, or e-mail (and mail) for short, is one of the most popular uses of the Internet. Once you have an e-mail account you can send an electronic message (sort of like a letter) to just about anyone else with an e-mail account so long as you know their e-mail address. The salient features of e-mail are: ....etc

The transmission energy required for a wireless communication increases superlinearly with the communication distance. In a mobile wireless network, nodal movement can be exploited to greatly reduce the energy required by postponing communication until the sender moves close to a target receiver, subject to application deadline constraints. In this paper, we characterize the fundamental performance limit, namely the lower bound expected communication distance, achievable by any postponement algorithm within given deadline constraints. Our analy ....etc

An Efficient Time-Bound Hierarchical Key Management Scheme for Secure Broadcasting-IEEE TRANSACTIONS ON DEPENDABLE AND SECURE COMPUTING, VOL. 5, NO. 2,
-java
Abstract—
In electronic subscription and pay TV systems, data can be organized and encrypted using symmetric key algorithms according to predefined time periods and user privileges and then broadcast to users. This requires an efficient way of managing the encryption keys. In this scenario, time-bound key management schemes for a hierarchy were proposed by Tzeng and Chien in ....etc
