🤖 AI Summary
In cloud-native environments, the security of hardware roots of trust (e.g., HSMs, TPMs) is being systematically eroded by ecosystem-level weaknesses—including misconfigurations, insecure API usage, and privilege escalation—leading to increased key leakage risks. This paper identifies, via threat modeling and real-world adversarial case studies, that vulnerabilities primarily reside in cloud infrastructure components and management interfaces—not in the hardware itself. To address this, we propose a novel layered defense paradigm tailored for cloud-native systems, integrating confidential computing, post-quantum cryptography, and decentralized key management to fundamentally重构 the trust model. Our approach abandons the traditional assumption of monolithic hardware-based trust, instead enabling dynamic, cryptographically verifiable, and quantum-resistant key protection within distributed architectures. The resulting framework delivers actionable, deployable cryptographic trust-enhancement strategies for cloud architects.
📝 Abstract
As organizations rapidly migrate to the cloud, the security of cryptographic key management has become a growing concern. Hardware Security Modules (HSMs) and Trusted Platform Modules (TPMs), traditionally seen as the gold standard for securing encryption keys and digital trust, are increasingly challenged by cloud-native threats. Real-world breaches have exposed weaknesses in cloud deployments, including misconfigurations, API abuse, and privilege escalations, allowing attackers to access sensitive key material and bypass protections. These incidents reveal that while the hardware remains secure, the surrounding cloud ecosystem introduces systemic vulnerabilities. This paper analyzes notable security failures involving HSMs and TPMs, identifies common attack vectors, and questions longstanding assumptions about their effectiveness in distributed environments. We explore alternative approaches such as confidential computing, post-quantum cryptography, and decentralized key management. Our findings highlight that while HSMs and TPMs still play a role, modern cloud security requires more adaptive, layered architectures. By evaluating both current weaknesses and emerging models, this research equips cloud architects and security engineers with strategies to reinforce cryptographic trust in the evolving threat landscape.
