Secure Data Transmission

Recently, the rate of data transfer over the internet globally has increased and this called for more data security as security of data is of great concern for individuals as well as business owners. Cryptography and steganography are two major key players for data security technique. Cryptography is use to perform encryption on the secrete message while steganography hides the secrete message in digital media, image in this regards. This paper employed these two techniques using Advanced Encryption Standard (AES) for the cryptography and Least Significant Bit (LSB) for the steganography. Combining the two algorithms ensured data integrity, data security, and flexibility. The changes in the secrete message carrier (Stego) is insignificant and is often not noticeable by the nicked eyes, thus this make the interception of the message often difficult by intruder.

Whether it's for work or personal well-being, keeping secrets or private information has become part of our everyday existence. Therefore, several researchers acquire an entire focus on secure transmitting secret information. Confidential information is collectively referred to as Steganography for inconspicuous digital media such as video, audio, and images. In disguising information, Steganography plays a significant role. Traditional Steganography faces a further concern of discovery as steganalysis develops. The safety of present steganographic technologies thus has to be improved. In this research, some of the techniques that have been used to hide information inside images have been reviewed. According to the hiding domain, these techniques can be divided into two main parts: The spatial Domain and Transform Domain. In this paper, three methods for each Domain have been chosen to be studied and evaluated. These are; Least Significant Bit (LSB), Pixel Value Difference (PVD), Exploiting Modification Direction (EMD), contourlet transform, Discrete Wavelet Transformation (DWT), and, Discrete Cosine Transformation (DCT). Finally, the best results that have been obtained in terms of higher PSNR, Capacity, and more robustness and security are discussed.

Secure encryption of data is one of the most important parts of information technology and major concern of data security, military, defense and homeland security applications. The main aim of the paper is to propose a new way of approach to encryption. We propose a new possible approach [1] to encryption, which could be a fast, simple, inexpensive, robust, flexible, and mobile way of data encryption for absolutely secure data transmission by using classical digital information. The Eavesdropper is allowed to know the received signal thus the method has a higher level of protection than that of quantum encryption. Factorization algorithms do not help to break the code. Proper scrambling operators, which are necessary for the method, are study of current research.

Cloud computing is one revolution in information technology (IT) that can share resources, services and data through a network among users. Because users have same rights on the network to transfer data, data are vulnerable to be attacked by unauthorized person. Lately, data security in a system only concentrates on data storage on cloud by utilizing internet security, but a little concentration is found during data transfer. By considering security as a serious problem, an encryption-based proposed system is presented to secure during data transfer. Authors propose an approach to boost system security during data transfer in order to prevent data theft by unauthorized person. To prevent an attack by unauthorized person, Advanced Encryption Standard (AES) will be proposed to secure data transfer and storage in cloud computing. For better future, authors will propose Systematic Literature Review (SLR) to generate suggestions and opportunities in AES cloud computing.

Growing attractiveness of Mobile Ad Hoc Networks (MANETs), its features, and usage has led to the launching of threats and attacks to bring negative consequences in the society. The typical features of MANETs, especially with dynamic topology and open wireless medium, may leave MANETs vulnerable. Trust management using uncertain reasoning scheme has previously attempted to solve this problem. However, it produces additional overhead while securing the network. Hence, a Location and Trust-based secure communication scheme (L&TS) is proposed to overcome this limitation. Since the design securing requires more than two data algorithms, the cost of the system goes up. Another mechanism proposed in this paper, Angle and Context Free Grammar (ACFG) based precarious node elimination and secure communication in MANETs, intends to secure data transmission and detect precarious nodes in a MANET at a comparatively lower cost. The Elliptic Curve function is used to isolate a malicious node, thereby incorporating secure data transfer. Simulation results show that the dynamic estimation of the metrics improves throughput by 26% in L&TS when compared to the TMUR. ACFG achieves 33% and 51% throughput increase when compared to L&TS and TMUR mechanisms, respectively.

<p align="center"><strong><em>Abstract</em></strong></p><p><em>There are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. One of the vulnerable parts of data security is when sending data to the destination. At the time of delivery, tapping of data can occur, so that people who are not entitled to get that information can find out. Therefore, an information needs to be secured so that only people who have access rights can know or get that information. And to maintain the confidentiality of the information, one of the ways is to insert the data into other objects, so that other people do not realize if the object contains important data or information. This hiding method is also known as steganography, and cryptography is added to strengthen the security of the data, that is a science and art to maintain the confidentiality of the message by encoding it in a form that is incomprehensible. The method used in steganography is Least Significant Bit (LSB), the algorithm used in cryptography is the Advanced Encryption Standard (AES), and the software development method used is prototype. The results of this study are all aspects of data security can be achieved, including when passing through the process of sending data through media such as the internet.</em></p><p><strong><em>Keyword: </em></strong><em>Steganography, Criptography, Prototype.</em></p><p align="center"><strong><em>Abstrak</em></strong></p><p><em>Ada beberapa aspek keamanan data yang harus dijaga, seperti: otentikasi, integritas, non repudiation, otoritas, kerahasiaan, privasi, dan kontrol akses.

In present world data transfer using the internet is growing. It is very easy and fast way to transfer information like confidential documents, economic transactions, business applications and other covert information over internet. With the advent and growth of internet, people are more concerned about security of information. Data Security is important while data is transferred over internet because any illegal user can access important and private data also make it worthless. Research in data security area will help government agencies, military organization and private companies to securely transmit their confidential data over internet. From past few years various steganography techniques have been developed to hide secret message using various multimedia objects having large amount of redundant data to support steganography. In this paper introduction about steganography, related concepts and implementation of commonly used spatial domain techniques like LSB(Least Significant Bit Technique) with modulus, PVD(Pixel Value Difference) with LSB replacement and adaptive data hiding over edges with LSB are considered. It is observed(while visual, statistical analysis and experiments were carried out) with benchmark cover and stego objects that embedding same amount of secret data in each pixel leads to more visible distortions in a stego image because all pixels do not bear same amount of changes and this effect is more observed in smooth area then edges. Improving stego image imperceptibility and adjusting hiding capacity adaptively are major related research challenges about spatial domain techniques.
