Abstract

The convergence of quantum computing threats and Zero Trust Architecture (ZTA) implementation presents unprecedented challenges for critical infrastructure protection. While quantum computers threaten current cryptographic foundations, Zero Trust frameworks require robust cryptographic mechanisms for continuous verification. This study examines the adaptation challenges and implementation strategies for integrating post-quantum cryptography within Zero Trust architectures across critical infrastructure sectors.A mixed-methods sequential explanatory design was employed with 147 critical infrastructure organizations across five sectors (energy, transportation, healthcare, financial services, telecommunications). Data collection included the Zero Trust Maturity Assessment Framework (ZTMAF), Post-Quantum Cryptography Readiness Index (PQCRI), Critical Infrastructure Vulnerability Assessment Protocol (CIVAP), semi-structured interviews (n=89), and document analysis (1,247 documents). Statistical analysis employed correlation analysis, ANOVA, and structural equation modeling, while qualitative data underwent thematic analysis.Zero Trust maturity varied significantly across sectors (M=2.91, SD=0.67), with financial services demonstrating highest maturity (M=3.81) and transportation lowest (M=2.50). Post-quantum cryptography readiness remained concerning across all sectors (M=2.47, SD=0.73), with only 16.3% achieving high readiness levels. Legacy systems prevalence (84.4% of organizations) negatively correlated with both ZTA maturity (r=-0.43) and PQC readiness (r=-0.58). Structural equation modeling revealed significant relationships between organizational factors and implementation success (x²/df=2.34, CFI=0.92).Critical infrastructure organizations face substantial challenges in quantum-safe Zero Trust implementation, with sector-specific barriers requiring targeted intervention strategies. The findings highlight urgent needs for government coordination, technical assistance programs, and accelerated legacy system modernization to ensure national cybersecurity resilience against emerging quantum threats.

Abstract

The post-pandemic transition brought significant changes in the higher education system, with hybrid learning becoming the dominant model. However, its impact on the psychological well-being of students has not been comprehensively explored. This study aims to analyze the influence of the intensity and configuration of hybrid learning on the dimensions of students' psychological well-being, as well as identify moderator factors such as digital literacy and belonging. The study uses a quantitative approach with an explanatory survey design. A sample of 250 students was selected through proportional stratified random sampling. The research instruments were questionnaires based on Ryff's Psychological Well-Being Scales (RPWB) and the hybrid learning intensity scale. Data were analyzed using multiple linear regression, Pearson correlation, and thematic analysis from semi-structured interviews. The results showed that offline presence had a significant effect on the dimensions of positive relations and self-acceptance, while asynchronous involvement contributed to autonomy and personal growth. Online synchronous sessions strengthen purpose in life and academic engagement. Digital literacy has been proven to increase environmental mastery, while a sense of belonging strengthens purpose in life and positive relationships. These findings confirm that a balanced hybrid learning design, supported by digital literacy and community building strategies, plays an important role in improving students' psychological well-being in the post-pandemic transition period.
