A Secured End to End Voice Transmission in Smartphone
...Show More Authors

The traditional voice call over Global System for Mobile Communications (GSM) and Public Switched Telephone Network (PSTN) is expensive and does not provide a secure end to end voice transmission. However, the growth in telecommunication industry has offered a new way to transmit voice over public network such as internet in a cheap and more flexible way. Due to insecure nature of the public network, the voice call becomes vulnerable to attacks such as eavesdropping and call hijacking. Accordingly, protection of voice call from illegal listening becomes increasingly important.
To this end, an android-based application (named E2ESeVoice application) to transmit voice in a secure way between the end users is proposed based on modified RC4. The performance of the proposed E2ESeVoice application is evaluated in terms of Mean Opinion Score (MOS) and computation time. The MOS score of E2ESeVoice application is measured with encrypted and unencrypted calls and resulted in values of 4.25 (Good) and 4 (Good) respectively. The result shows that the MOS of both tests is comparable and the encryption has not affect the quality of voice.

This study was for searching for Cholera Bacteria serotype which causes epidemiology Cholera in the 2007 in a fast method which contains (Rapid Visual Test) (Crystal V.C.) which was used for the first time in Iraq to diagnosis of Cholera Bacteria & compared with the traditional bacteriology method. The Cholera disease is one of the most dangerous epidemiological diseases which lead to death with a percentage of (50 – 70) % in the severe cases for untreated patients . For this purpose, 100 samples of stool from the patients from a (13) hospitals in Baghdad Governorate in the period from August to the end of December. The Cholera was diagnosis in two methods, 1st method was the fast method using the nitrocellulose which is coated with anti-

Vorwort:

                              Die Übersetzung gilt in der Vergangenheit als Brücke zwischen  verschiedenen Gesellschaften. Sie spielt eine große Rolle im Bereich Kulturaustausch der Länder. Die Araber haben das früh betrachtet, und die Übersetzung als Wissenschaft wird eine der wichtigsten Lehren. Viele griechische Wissenschaften waren durch Übersetzung in den arabischen Ländern bekannt.

In dieser Forschung findet man einen Überblick über die Wichtigkeit der Sprichwörterübersetzung und welche Rolle spielt diese Übersetzung im Z

The morphological structure of nouns and verbs in the novel "Astonishment" by the novelist Aharon Applefield, Morphological study.: מבנה שמות עצם והפעלים ברומן תימהון לסופר אהרון אפלפלד עיון מורפולוגי
...Show More Authors

This research sheds light on the morphological structure of nouns and verbs in the novel "ASTONISHMENT" by the novelist Aharon Applefield by analysing selected models from the novel in a morphological analysis in order to identify the most important morphological features of this structure according to a statistical analytical approach.

 The morphological structure is the main pillar of the linguistic structure of the literary text. Morphology is the science that studies the word, by which its structure and original letters are known, and the change that has occurred to it.  The aesthetics of the fictional text is reflected in this structure, through which the writer conveys his ideas and narrations to the reader.  The research

Securing Text Messages Using Graph Theory and Steganography
...Show More Authors

      Data security is an important component of data communication and transmission systems. Its main role is to keep sensitive information safe and integrated from the sender to the receiver. The proposed system aims to secure text messages through two security principles encryption and steganography. The system produced a novel method for encryption using graph theory properties; it formed a graph from a password to generate an encryption key as a weight matrix of that graph and invested the Least Significant Bit (LSB) method for hiding the encrypted message in a colored image within a green component. Practical experiments of (perceptibility, capacity, and robustness) were calculated using similarity measures like PSNR, MSE, and

Text Compression & Encryption Method Based on RNA and MTF
...Show More Authors

The sending of information at the present time requires the speed and providing protection for it. So compression of the data is used in order to provide speed and encryption is used in order to provide protection. In this paper a proposed method is presented in order to provide compression and security for the secret information before sending it. The proposed method based on especial keys with MTF transform method to provide compression and based on RNA coding with MTF encoding method to provide security. The proposed method based on multi secret keys. Every key is designed in an especial way. The main reason in designing these keys in special way is to protect these keys from the predication of the unauthorized users.

Novel Dynamic S-Box Based on Password Key and Circle Map
...Show More Authors

     Many cryptosystems and security techniques use substitution boxes to ensure the data’s secure communication. A new technique is presented for generating a robust S-box to fulfill security requirements. The AES algorithm represents a block cipher cryptographic algorithm. It was selected by the National Institute of Science and Technology as the optimal cryptographic algorithm in 2011. Through the study of the properties of original S-BOX, this algorithm has been subjected to a number of attacks (linear, differential, statistical, and interpolation), and original S-BOX has been static, which makes the attack strong and shows a weakness in the algorithm.  It is necessary to make this algorithm more efficient and powerful through
