Research ArticleOpen accessIn the keywordsA 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 accessIn the keywordsDigital Identities and the Promise of the Technology Trio: PKI, Smart Cards, and BiometricsA. M. Al-Khouri, J. BalThis article looks at one of the evolving crimes of the digital age; identity theft. It argues and explains that if three key technologies were implemented together namely biometrics, smart cards, and PKI, then they can deliver a robust and trusted identification and authentication infrastructure. The article concludes that such infrastructure may provide the foundation for e-government and e-commerce initiatives … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,783 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA CAE Scheme Using ECC Based Self Certified PKCManoj Kumar Chande, Cheng-Chi Lee, Chun-Ta LiThe Convertible Authentication Encryption (CAE) scheme, allows the signer to generate an authentic ciphertext signature, which can be recuperated and validated by a specific recipient only. In case of any kind of dispute the recipient is capable enough to convert the ciphertext signature as a normal signature and that can be validated publicly. The CAE schemes are used for transformation … …Journal of Computer Science, Vol. 12, Issue 11 · 23 Dec 2016 · 6,904 accessesView PDFCite

RajaramProblem statement: With the explosive growth of and internet and web applications many emerging group-oriented distributed applications such as tele/video-conferencing, multiplayer games are based on group communication model that need security services such as privacy and data integrity Hence a secure distributed group key agreement is required to establish and authenticate a common group key for secure and private communication. … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,643 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 abstractA Multiphase Zero-Trust Authentication Framework Using Replicated and Homomorphic EncryptionModisaotsile Marope, Venumadhav Kuthadi, Rajalakshmi Selvaraj et al.In response to the increasing complexity and vulnerability of traditional authentication techniques, this paper proposes the Multiphase Zero-Trust Authentication Framework (MZTAF), which combines device-level and user-level authentication to enhance security in zero-trust environments. Phase I leverages replicated key-based authentication to ensure fault tolerance and reduce the risk of device-level compromise. Phase II introduces homomorphic encryption for user authentication, securely verifying … …Journal of Computer Science, Vol. 22, Issue 2 · 19 Feb 2026 · 1,657 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Lightweight and Privacy-Preserving Biometric Authentication Framework for Sustainable IoMT SystemsSaima Anwar Lashari, Mahmood A. Al-Shareeda et al.Biometric authentication provides secure, identity-bound access control for the Internet of Medical Things (IoMT), crucial for wearable, implantable, and ambient devices. However, the inherent immutability and sensitivity of biometric data pose severe privacy risks in the event of a breach. Furthermore, conventional public-key cryptography is often too computationally intensive for resource-constrained IoMT hardware. To address these challenges, this paper proposes … …Journal of Computer Science, Vol. 22, Issue 1 · 9 Feb 2026 · 1,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnonymous and Distributed Authentication for Peer-to-Peer NetworksPasan Tennakoon, Supipi Karunathilaka, Rishikeshan Lavakumar et al.Well-known authentication mechanisms such as Public-key Infrastructure (PKI) and Identity-based Public-key Certificates (ID-PKC) are not suitable for integration in a Peer-to-Peer (P2P) network environment, the reason being either the lack of or the difficulty in maintaining a centralized authority to manage the certificates. Authentication becomes even harder in anonymous environments. In this study, we present three authentication protocols such that … …Journal of Computer Science, Vol. 19, Issue 1 · 3 Jan 2023 · 6,539 accessesView PDFCite
