Review ArticleOpen accessPhrase in the titleA Proposed an Enhanced Authentication and Dual Encryption Algorithm: Secured Video Transmission in Surgical Tele-TrainingAnil Wagle, Abeer Alsadoon, P.W.C. Prasad et al.Implementation of tele-training for trainee surgeons has been slow to date as current standards of video transmission do not meet requirements for security, speed and clarity for such videos. The aim of this paper is to increase security by providing enhanced authentication as well as improving the overall throughput of the system. The proposed solution consists of a dual encryption … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 28 Dec 2018 · 7,772 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleImplementation of an Improved Data Encryption Algorithm in a Web Based Learning SystemAdeolu Olabode Afolabi, Rotimi AdagunodoProblem statement: This study proffered solution to some identified data insecurity problems in software development by the use of Web-based learning system as a test bed and development of an hybrid crypto-biometric security system. Approach: A variant of data encryption algorithm tagged (XOR-RSA algorithm) is developed in order to encrypt the messages being sent between the learner and the facilitator. … …Physics International, Vol. 2, Issue 1 · 23 Jan 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleApplication 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 accessPhrase in the titleA Key Dependent Encryption Algorithm Based on Multiple Bitwise-Shuffling and XOR Variable-Length PartitionsAbdelfatah Aref TamimiThis new algorithm employs shuffling procedures combined with variable-length key-dependent XOR and S-box substitutions to perform lossless image encryption. This algorithm was implemented and tested by performing different permutations of shuffling, XOR encryption and S-box substitution. Empirical analysis using different types of test images of different sizes showed that this new algorithm is effective and resistant to statistical attacks. The … …Journal of Computer Science, Vol. 12, Issue 2 · 26 Mar 2016 · 7,679 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleImpact of Asymmetric Encryption Algorithms in a VANETEdward David Moreno, Leila C.M. Buarque, Florêncio Natan et al.This paper describes the impact of using asymmetric encryption algorithms, with emphasis on RSA, ECC and Multivariate Quadratic Quasigroup (MQQ) algorithms, in a scenario of Vehicular Ad hoc Network (VANET). In the research we used the simulator NS-3 with specific module for vehicular networks. The algorithms were implemented in C and were included in NS-3. The results, even in a … …Journal of Computer Science, Vol. 11, Issue 12 · 30 Jan 2016 · 6,852 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMessage Based Random Variable Length Key Encryption AlgorithmHamid Mirvaziri, Kasmiran Jumari Mahamod Ismail, Zurina Mohd HanapiProblem statement: A block ciphers provides confidentiality in cryptography but cryptanalysis of the classical block ciphers demonstrated some old weaknesses grabbing a partial key in any stage of encryption procedure leads to reconstructing the whole key. Exhaustive key search shows that key generation should be indeterminist and random for each round. Matching cipher-text attack shows that larger size of block … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,804 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Shuffle Image-Encryption AlgorithmA. A. Yahya, A. M. AbdallaProblem statement: Image encryption needs to be secure by resisting statistical attacks and other types of attacks. Approach: The new algorithm, call it the Shuffle Encryption Algorithm (SEA), applies nonlinear s-box byte substitution. Then, it performed a shuffling operation partially dependent on the input data and uses the given key. Results: SEA was implemented and tested with different data, mainly … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Jul 2009 · 8,353 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleIMPLICATIONS OF BITSUM ATTACK ON TINY ENCRYPTION ALGORITHM AND XTEAAmandeep, G. GeethaTEA and XTEA are block ciphers that uses Fiestal structure. We enciphered a fixed message with different keys using TEA and XTEA cryptographic algorithms. Our interest was to find the correlation of the bitsum of the ciphertext with the bitsums of the corresponding keys. In our attempt, we found that for specific patterns of keys, whatever be the plaintext, the … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 7,364 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Algorithm for Digital Video EncryptionSamsul Arifin, Wihikanwijna, Tuga Mauritsus et al.This research aims to propose a safe digital video data alternative employing symmetric cryptography and an encryption technique using Partition. The Hill Cipher method requires a square key matrix with an inverse modulo the unimodular matrix is one of the unique matrices with an inverse. The encryption mechanism is modulo matrix multiplication, with shift cipher encryption employed to encrypt defective … …Journal of Computer Science, Vol. 19, Issue 7 · 19 Jun 2023 · 6,395 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMDS Algorithm for EncryptionMani Arora, Derick Engles, Sandeep SharmaMost of the encryption algorithms used today generates huge cipher messages as well as long encryption keys. These approaches require time and are computationally intensive .While sending data packets through the network a compression technique along with cryptography can be applied to reduce the data packet size for better bandwidth utilization and hence faster transmission of data.
