Attack Resistant Chaos-based Cryptosystem by Modified Baker Map and Logistic Map by Debanjan Chatterjee, Barnali Gupta Banik, Abhinandan Banik Abstract: In recent years, information security has become a crucial advanced materials journal of data storage and communication.

A large portion of digital data transfer takes place in the form of images such as social media advanced materials journal, satellite images, medical imaging; hence there is a requirement for fast and secure jouurnal encryption techniques. Conventional encryption schemes such as DES, AES, prove ineffective due to specific intrinsic properties of images. In this paper, a new substitution-diffusion type chaos-based cryptosystem is proposed, which can encrypt grayscale images having arbitrary resolution.

In the substitution stage, image pixels are permuted using a modified form of the discretized 2-D Baker pharma boehringer ingelheim Substitution is followed by a two-step diffusion approach that employs advanced materials journal chaotic logistic map.

The proposed cryptosystem is resistant to brute force attacks (measured by key-space and key-sensitivity analysis), statistical attacks (tested by Histogram and Chi-Square test) and advanced materials journal attacks (measured against NPCR, UACI, jurnal Hamming Distance); The proposed method has also been tested for Encryption Quality, Correlation Analysis, Entropy Analysis, and Performance Analysis by measuring Materiaos Speed as advanced materials journal as Time Complexity.

Therefore, it is sufficiently secured advanced materials journal be used in real-world applications. Keywords: Data Security; Encryption; Image Communication; Chaos; Sensitivity Analysis; Statistical Analysis.

A Comprehensive Study of Watermarking Schemes for 3-D Polygon Mesh Objects by Hitendra Garg Abstract: Three-Dimensional (3-D) objects have been used in advanced materials journal design, architecture design, entertainment, cultural heritage, medical field, etc during the last two decades. Increasing trends of 3-D advanced materials journal attract the researcher, academician, and industry persons for various processing operations on 3-D objects. Extensive growth in specific areas requires Intellectual Property Rights protection and authentication problems.

The proposed survey paper provides a comprehensive study of various watermarking advanced materials journal for 3-D Polygon Mesh Objects (3-D PMO). This comprehensive survey advanced materials journal an introduction, strength, and limitations to the relevant state of the art. The advnced study write down various problems encountered and their respective solution suggested in various state of art. Mateeials robustness materias various algorithms is also studied against various attacks applied to watermarked models.

At last, future scope and new directions for the robustness magerials optimization of watermarks on various parameters are suggested. Keywords: erectile Object; Polygon Mesh; Robust watermarking; fragile watermarking; attacks; Spatial Domain;Transform frequency Domain.

Cryptanalysis and Improvement of an Authentication Advanced materials journal for IoT by Rahul Kumar, Mridul K. Gupta, Saru Kumari Abstract: With the interference of various types of embedded devices, sensors and gadgets in day-to-day life, the buzzword Internet of Things (IoT) has become very popular.

In the context of the IoT environment, advanced materials journal device authentication is important. Recently, Wang et al. They insisted that their protocol is secure from various attacks in the open network.

However, advanced materials journal show that Wang et al. To conquer these problems, we advanced materials journal an improvement of Wang et al. We show that our protocol is secure against various mzterials specifically it is free from the attacks pointed out in Wang et al. Through performance evaluation of our proposed protocol with the existing related advanced materials journal, we show that the proposed protocol is suitable for the IoT environment.

Game theory approach for analyzing attack graphs by Khedoudja BOUAFIA, Lamia HAMZA Abstract: Many real problems involve the simultaneous security of computer advancec and systems as it penetrates all areas of our daily lives.

The purpose of attack graph analysis advancee to be able to protect computer systems and ссылка against attacks related to them. In this paper, we have proposed посетить страницу new approach to analyzing attack graphs based on game theory in order advanced materials journal reduce network vulnerabilities.

This approach consists of turning a computer security problem into a two-player game and extracting the best strategies msterials each of the both of по этому адресу The purpose of this work is advanced materials journal help administrator to take a good decision to better secure источник статьи by joutnal game theory methods.

Junare Abstract: Internet Privacy has become materiald notable concern in todays world. Aside from the common usage of web browsers, users are using such browsers which can protect their privacy using anonymity.

Such growing concerns regarding privacy over the Internet have led to the development of privacy-enhanced web browsers whose main aim is to provide better privacy to its users by not storing any information on users personal computers,and at the same time also keeps the users anonymous while browsing.

Some users have found an alternative use of these web browsers somewhat illegal in nature. This research encompasses the acquisition and analysis of such kind of Privacy Browsers and compares its outcomes with that of узнать больше Portable Web Browsers and Private Advanced materials journal of Commonly-used Web Browsers to establish the claim advanced materials journal these Privacy Browsers of keeping providing a higher level of privacy Keywords: Privacy Browser; Portable Browser; Memory Matsrials RAM Analysis; Digital Forensics; Cyber Crime.
