https://research.adra.ac.id/index.php/quantica <p style="text-align: justify;"><strong>Journal of Tecnologia Quantica </strong>is dedicated to bringing together the latest and most important results and perspectives from across the emerging field of quantum science and technology. <strong>Journal of Tecnologia Quantica </strong>is a highly selective journal; submissions must be both essential reading for a particular sub-field and of interest to the broader quantum science and technology community with the expectation for lasting scientific and technological impact. We therefore anticipate that only a small proportion of submissions to <strong>Journal of Tecnologia Quantica </strong>will be selected for publication. We feel that the rapidly growing QST community is looking for a journal with this profile, and one that together we can achieve. Submitted papers must be written in English for initial review stage by editors and further review process by minimum two international reviewers.</p> Yayasan Adra Karima Hubbi en-US Journal of Tecnologia Quantica 3062-6757 https://research.adra.ac.id/index.php/quantica/article/view/2794 <p>The emergence of large-scale quantum computers poses a critical threat to classical public-key cryptographic systems, prompting the rapid development of post-quantum cryptography as a foundational component of future digital security. Lattice-based and code-based algorithms have become leading candidates due to their strong conjectured resistance to quantum attacks; however, their comparative security characteristics remain insufficiently examined under unified analytical frameworks. This study aims to provide a comprehensive security analysis of lattice-based and code-based post-quantum cryptographic algorithms by evaluating their resilience against known classical and quantum attack vectors. A structured methodological approach is employed, combining complexity-theoretic assessment, parameter-sensitivity evaluation, and simulated attack modeling across representative schemes such as CRYSTALS-Kyber, NTRU, Classic McEliece, and BIKE. The results indicate that lattice-based schemes offer strong security margins under current attack models but exhibit notable sensitivity to parameter misconfiguration and structured lattice weaknesses. Code-based schemes demonstrate exceptional robustness due to the hardness of decoding random linear codes, yet face practical limitations in key size and implementation overhead. The study concludes that both families remain viable for post-quantum standardization, although their security assurances depend heavily on careful parameter selection and continued cryptanalytic scrutiny as quantum hardware evolves.</p> <p>&nbsp;</p> Loso Judijanto Zhou Hui Sun Wei Copyright (c) 2025 Loso Judijanto, Zhou Hui, Sun Wei https://research.adra.ac.id/index.php/quantica/index 2025-12-23 2025-12-23 3 2 13 25 10.70177/quantica.v2i5.2794
