Research ArticleOpen accessPhrase in the titleAttack of Against Simplified Data Encryption Standard Cipher System Using Neural NetworksKhaled M. Alallayah, Waiel F. Abd El-Wahed, Mohamed Amin, Alaa H. AlhamamiProblem statement: The problem in cryptanalysis can be described as an unknown and the neural networks are ideal tools for black-box system identification. In this study, a mathematical black-box model is developed and system identification techniques are combined with adaptive system techniques, to construct the Neuro-Identifier. Approach: The Neuro-Identifier was discussed as a black-box model to attack the target cipher … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Unimodular Hill Cipher and RSA Methods to Text Encryption Algorithms Using PythonSamsul Arifin, Dwi Wijonarko, Suwarno, Edwin Kristanto SijabatText encryption is one of the techniques used to maintain the confidentiality of information in digital communications. In this study, we propose to apply a combination of the Unimodular Hill Cipher and RSA methods to a text encryption algorithm using the Python programming language. The Unimodular Hill Cipher method uses an unimodular matrix to replace text characters with encrypted characters, … …Journal of Computer Science, Vol. 20, Issue 5 · 1 Mar 2024 · 6,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractSegmented Block Cipher Algorithm Based on ASCII-Codes ManeuverShadi Rasheed Masadeh, Hamza Abbass Al-SewadiDue to their complexity, computation time and power requirement, the secure and widely used cryptographic systems such as 3DES and AES may not be considered suitable for applications like mobile and remote sensing of sensitive data. Therefore, secure but less complicated algorithms for data encryption are still sought. This paper suggests a new Segmented Block Cipher Algorithm (SBCA) is a … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 6,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractMETADATA DRIVEN EFFICIENT KEY GENERATION AND DISTRIBUTION IN CLOUD SECURITYR. Anitha, Saswati MukherjeeWith rapid development of cloud computing to a greater extent IT industries outsource their sensitive data at cloud data storage location. To keep the stored data confidential against untrusted cloud service providers, a natural way is to store only encrypted data in the cloud severs and providing an efficient access control mechanism using a competent cipher key-Cmxn, which is becoming … …Journal of Computer Science, Vol. 10, Issue 10 · 12 May 2014 · 6,622 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Multicrypt Encryption MechanismRhymend Uthariaraj Vaidyanathan, Lydia Elizabeth Benjamin, John Prakash ArockiasamyMulticast communication allows a single message packet to be routed to multiple nodes simultaneously. Membership in a multicast group is dynamic, allowing nodes to enter and leave the multicast session. Besides the benefits, multicast communication presents the challenge of securing the communication. In order to preserve confidentiality the general encryption mechanism used for point to point communications are used. A … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 4 Sep 2012 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultimodal Biometric-based Secured Authentication System using SteganographyB. Shanthini, S. SwamynathanProblem statement: The main challenge in the design of a security system for high security mobile ad OC network is how to prevent the attacks against data modification and authentication. Approach: In this novel proposed system the messages communicated between the users are encrypted by the cancellable cryptographic key generated from fingerprint features of the receiver by applying genetic operators … …Journal of Computer Science, Vol. 8, Issue 7 · 7 May 2012 · 7,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Chaotic Block Cipher for Real-Time MultimediaN. Radha, M. VenkatesuluProblem statement: The widespread use of image, audio and video data makes media content protection increasingly necessary and important. We propose a naive approach which treats the multimedia signal to be protected as a text and use proposed encryption design to encrypt the whole data stream. Upon reception, the entire cipher text data stream would be decrypted and playback can … …Journal of Computer Science, Vol. 8, Issue 6 · 27 Apr 2012 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Algorithm and Tabu Search Attack on the Mono-Alphabetic Substitution Cipher in Adhoc NetworksA. K. Verma, Mayank Dave, R. C. JoshiWith exponential growth of networked system and application such as e-Commerce, the demand for effective Internet security is increasing. Cryptology is the science and study of systems for secret communication. In consists of two complementary fields of study: cryptography and cryptanalysis. This study presents a cryptanalysis method based on Genetic Algorithm and Tabu Search to break a Mono-Alphabetic Substitution Cipher … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,254 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSecure Packet Encryption and Key Exchange System in Mobile Ad hoc NerworkSudhakar Sengan, S. Chenthur PandianProblem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,387 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNew Approaches to Ancient Crypto-Steganography MethodsA. Joseph Raphael, V. SundaramProblem statement: The requirement and ability to hide information from others has existed in the world for centuries. Cryptography and steganography are the most commonly used techniques for information sharing. The science of securing a data by encryption is cryptography whereas the method of hiding secret messages in other media is Steganography, so that the secret’s very existence is concealed. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 4 Nov 2011 · 8,110 accessesView PDFCite
