Research ArticleOpen accessEvery word in the titleOne Time Password (OTP) Solution for Two Factor Authentication: A Practical Case StudyOscar Efrén Acosta Mayorga, Sang Guun YooCurrently, static passwords are no longer secure, they expose accounts and data, more advanced and sophisticated approaches are required to guarantee user authentication and operations in digital systems. In this context, this study investigates how in a practical application, addressing security challenges in user authentication using One Time Passwords (OTP) can strengthen two-Factor Authentication (2FA), the use of a sec … …Journal of Computer Science, Vol. 21, Issue 5 · 26 Apr 2025 · 8,452 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Practical and Secure Hash Function-Based Password Authentication SchemeMuhammad Helmi Ali, Eddie Shahril Ismail, Firdaus Mohamad HamzahIn this study, we propose a practical and secure hash function-based password authentication scheme using smart cards. Our proposed scheme offers some advantages and interesting features. Firstly, the scheme does not require a verification table and is secure against the replay attacks, an attack that most of the existing schemes suffer. Secondly, any user of the scheme be allowed to … …Journal of Computer Science, Vol. 15, Issue 7 · 17 Jul 2019 · 7,738 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTwo Factor Authentication for e-Government Services using Hardware-Like One Time Password GeneratorsGiuseppe Della Penna, Pietro Frasca, Benedetto IntrigilaA safe and accessible authentication technique is a prerequisite for any modern e-government application. Two-factor authentication is currently widely adopted, since it alleviates many vulnerabilities of password-based authentication. The majority of e-government systems currently make use of text messages to deliver the second authentication factor, but these messages do not constitute an adequate (secure and reliable) solution. In this paper … …Journal of Computer Science, Vol. 15, Issue 1 · 26 Jan 2019 · 8,167 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluating Password Behavior at a Small UniversityMohammed Awad, Zakaria Al-Qudah, Sahar Idwan, Abdul Halim JalladNo matter how sophisticated an organization’s security system is, it remains vulnerable due to the human factor. In this study, we surveyed and analyzed the patterns practiced by users when generating passwords at a small-sized university. We found that users are not as aware of security requirements and practices as they think. Moreover, the vast majority of users’ passwords are … …Journal of Computer Science, Vol. 15, Issue 1 · 4 Jan 2019 · 9,044 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Secure Passwordless Multi-Server Modified Authenticated Master-Key Agreement Scheme Based on Hardware-Software and Iriscode Identifiers Through SSL/TLS Protocol for E-learning and Similar Web-based ServicesAfshin Zivi, Gholamreza FarahaniThere is a growing concern about systems security and how to organize it. This is because the internet which is the backbone of all systems is regarded as unsafe. Also, the internet transmits all connection transactions in the E-learning and similar web-based systems and as a result, intruders and attackers by abusing security holes can compromise the system. The E-learning … …Journal of Computer Science, Vol. 14, Issue 10 · 26 Oct 2018 · 7,257 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGRID-IMAGE PASSWORD BASED SCHEME: ENHANCING MEMORABILITY FEATURES OF PASSWORDSObasan Adebola, Norafida Ithnin, Mohd Zalisham JaliPassword authentication has become a widely recognized element of computer security practices where human users are proven or confirmed as legitimate users for access to secure systems. Using this system, every user needs to recall its password correctly before access can be granted to an intended services or applications. Remembering the secure passwords is an everyday problem for users because … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 9 Sep 2014 · 6,673 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntegrated Quantum and Classical Key Scheme for Two Servers Password AuthenticationA. Krishnan, T.S. ThangavelProblem statement: Traditional user authentication system uses passwords for their secured accessibility in a central server, which is prone to attack by adversaries. The adversaries gain access to the contents of the user in attack prone servers. To overcome this problem, the multi-server systems were being proposed in which the user communicate in parallel with several or all of the … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 6,644 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Non-Exchanged Password Scheme for Password-Based Authentication in Client-Server SystemsShakir M. Hussain, Hussein Al-BahadiliThe password-based authentication is widely used in client-server systems. This research presents a non-exchanged password scheme for password-based authentication. This scheme constructs a Digital Signature (DS) that is derived from the user password. The digital signature is then exchanged instead of the password itself for the purpose of authentication. Therefore, we refer to it as a Password-Based Digital Signature (PBDS) … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,002 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Password-Based Key Derivation Algorithm Using the KBRP MethodShakir M. Hussain, Hussein Al-BahadiliThis study presents a new efficient password-based strong key derivation algorithm using the key based random permutation the KBRP method. The algorithm consists of five steps, the first three steps are similar to those formed the KBRP method. The last two steps are added to derive a key and to ensure that the derived key has all the characteristics of … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMulti-Factor Authentication for e-Government Services using a Smartphone Application and Biometric Identity VerificationMohammad AlRousan, Benedetto IntrigilaThe growing usage of smartphones and tablets has a significant impact on e-government services, according to Cisco and accounted for 59 percent of total IP traffic during 2018. In the provision of e-government services, usernames and passwords are still the most common authentication scheme. A password, however, is a weak authentication scheme, as it can easily be hacked over an … …Journal of Computer Science, Vol. 16, Issue 2 · 20 Feb 2020 · 7,839 accessesView PDFCite
