Implementation of Grover’s Algorithm in a Cold-Boot Attack Scenario for RYDE

Juan D. Sanchez

Post-quantum digital signature schemes aim to remain secure against quantum adversaries, yet their practical security may be affected by physical attacks. This work studies the use of Grover’s algorithm in a Cold Boot Attack scenario against the RYDE post-quantum digital signature scheme. We construct a quantum oracle adapted to the RYDE key derivation process and analyze the corresponding Grover operator. Furthermore, we estimate the required quantum resources, including the number of quantum registers and quantum gates. This study provides insight on the feasibility of quantum-assisted attacks on seed-based post-quantum digital signature schemes.

Post-Quantum Trusted Computing: Architectural Approaches, Standardization, and Open Challenges in the Quantum Era

Volkan Erol

Trusted Computing (TC), which has long been the cornerstone of hardware-based platform integrity, faces an existential threat from the advent of large-scale quantum computers capable of breaking its underlying classical cryptography. This review systematically analyzes the imperative transition to Post-Quantum Trusted Computing (PQC-TC), synthesizing the leading research and industry-driven efforts to secure this critical paradigm. We present a taxonomy of PQC-TC approaches, including the PQC modernization of existing Trusted Platform Modules (TPMs) for functions like measured boot and remote attestation. Our analysis highlights the dual challenges of adapting to new algorithms with significantly larger key sizes and higher computational overheads, as well as the need for robust migration strategies. We examine the pivotal roles of the NIST PQC Standardization Process and the Trusted Computing Group (TCG) in defining the path to commercial readiness. While PQC modernization is the most viable nearterm solution, we identify open research challenges in formal security modeling, resource optimization for embedded systems, and the long-term potential of hybrid architectures integrating quantum hardware. This paper concludes that the successful evolution of TC hinges on proactive, collaborative efforts to build a secure, resilient, and quantum-ready foundation for future digital systems.
