Research ArticleOpen accessPhrase in the titleA MODIFIED ELLIPTIC CURVE DIGITAL SIGNATURE ALGORITHM FOR PUBLIC VERIFIABILITY WITH DATA DYNAMICS IN CLOUD COMPUTINGD. Sumathi, Ramachandra V. PujeriCloud storage is considered to be the most critical factor in decision making for users as it largely scales down the infrastructure in terms of size, cost and design. Considering factors such as local storage cost, maintenance a single server model can support multiple users on a needed basis. This raises concerns for integrity verification i.e., assuring the correctness of … …Journal of Computer Science, Vol. 10, Issue 10 · 28 Jun 2014 · 6,486 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA New Digital Signature Scheme Based on Factoring and Discrete LogarithmsE.S. Ismail, N.M.F. Tahat, R.R. AhmadProblem statement: A digital signature scheme allows one to sign an electronic message and later the produced signature can be validated by the owner of the message or by any verifier. Most of the existing digital signature schemes were developed based on a single hard problem like factoring, discrete logarithm, residuosity or elliptic curve discrete logarithm problems. Although these schemes … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,259 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA New Digital Signature Scheme Based on Mandelbrot and Julia Fractal SetsMohammad Ahmad Alia, Azman Bin SamsudinThis paper describes a new cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Having fractal based digital signature scheme is possible due to the strong connection between the Mandelbrot and Julia fractal sets. The link between the two fractal sets used for the conversion of the private key to the public key. Mandelbrot fractal function takes the … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,962 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Comparative Study of RSA Based Digital Signature AlgorithmsRamzi A. Haraty, A. N. El-Kassar, Bilal ShibaroA digital signature is a mechanism designed to allow secure communication through an insecure medium and can be traced in many applications where privacy is required. A digital signature is an electronic signature that can be used to authenticate the identity of the sender of a message or the signer of a document and possibly to ensure that the original … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,432 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication of Elliptic Curve Crypto System to Secure Multi-Signature Bitcoin Block ChainMohammed Mujeer Ulla, Deepak S. SakkariBlockchain is a technology that enables decentralized digital currencies like bitcoin, ethereum, and ripple. It is widely used in many areas such as healthcare, defense, and industrial domains like internet of things for tracking sensor data and detecting duplicate sensor data. Bitcoin is one of the most popular cryptocurrencies due to its market value and use as a medium of … …Journal of Computer Science, Vol. 19, Issue 1 · 30 Jan 2023 · 5,975 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSecurity in MANET’s by Using Detective Signature TechniquesGayathri A., P. NarayanasamyMobile Ad-hoc Network (MANET) is one among the fastest growing area in the field of research where security is a vital factor for protecting MANET against attacks, EAACK is an acknowledgement based IDS which is composed of three parts namely, ACK, S-ACK and MRA along with digital signature to provide security against attacks. Till now contemporary technique such as EAACK … …Journal of Computer Science, Vol. 11, Issue 3 · 21 Apr 2015 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the keywordsENHANCING SECURITY FOR IPV6 NEIGHBOR DISCOVERY PROTOCOL USING CRYPTOGRAPHYRosilah Hassan, Amjed Sid Ahmed, Nur Effendy OsmanInternet Protocol version 4 (IPv4) would gradually be replaced by Internet Protocol version 6 (IPv6) as the next generation of Internet protocol. The Neighbor Discovery Protocol (NDP), one of the main protocols in the IPv6 suite, comprises Neighbor Discovery for IPv6. NDP is used by both hosts and routers. Its functions include Neighbor Discovery (ND), Router Discovery (RD), Address Auto … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 3 Jul 2014 · 7,703 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCERTIFICATE AUTHORITY SCHEMES USING ELLIPTIC CURVE CRYPTOGRAPHY, RSA AND THEIR VARIANTS-SIMULATION USING NS2S. Shivkumar, G. UmamaheswariA PKI (public key infrastructure) enables users of a basically unsecure public network to securely and privately exchange data through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority. The public key infrastructure provides for a digital certificate that can identify an individual or an organization and directory services … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 18 Dec 2013 · 7,379 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnergy Constrained Secure Hierarchical Data Aggregation in Wireless Sensor NetworksV. Bhoopathy, R. M.S. ParvathiProblem statement: Wireless sensor networks, brings out variety of different challenges at energy level, integrity, authentication, communication cost. Approach: In the secure data aggregation techniques, reduction in the energy consumption was not elaborated in detail, since aggregator means of connection to sink was either direct or through other aggregators which need high energy level. Results: We suggest an Energy Constrained … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 16 Mar 2012 · 7,377 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFish Classification Based on Robust Features Extraction From Color Signature Using Back-Propagation ClassifierMutasem Khalil Alsmadi, Khairuddin Bin Omar, Shahrul Azman Mohd NoahProblem statement: Image recognition was a challenging problem researchers had been research into this area for so long especially in the recent years, due to distortion, noise, segmentation errors, overlap and occlusion of objects in digital images. In our study, there are many fields concern with pattern recognition, for example, fingerprint verification, face recognition, iris discrimination, chromosome shape discrimination, optical … …Journal of Computer Science, Vol. 7, Issue 1 · 27 Dec 2010 · 8,636 accessesView PDFCite
