Quantum computing poses a critical threat to existing cryptographic primitives, rendering current access control mechanisms in cloud-native infrastructures vulnerable to compromise. This paper introduces a comprehensive quantum-resilient access control framework specifically engineered for distributed, containerized, and zero-trust environments. The proposed system integrates post-quantum cryptographic (PQC) primitives—specifically lattice-based key encapsulation (Kyber) and digital signatures (Dilithium)—with a hybrid key exchange protocol to maintain crypto-agility and backward compatibility. We design a secure token issuance and verification process employing PQC-based authentication, ensuring resistance to both classical and quantum adversaries. A prototype implementation demonstrates that our hybrid PQC approach incurs a moderate computational overhead of approximately 10–30\% while preserving horizontal scalability and interoperability across Kubernetes clusters. Security analysis under the post-quantum adversary model confirms resistance to key compromise, replay, and forgery attacks. The results highlight that quantum-resilient access control protocols can be efficiently integrated into modern cloud infrastructures without sacrificing scalability, performance, or operational flexibility.
We extend the security analysis of continuous variable quantum-key-distribution protocols using a family of post selection schemes to account for arbitrary eavesdropping attacks. We show that the postselection protocol is equivalent to a virtual entanglement-based protocol including a distillation stage. We introduce a particular `Gaussian' post selection and demonstrate that the security can be calculated using only experimentally accessible quantities. Finally, we explicitly evaluate the performance for the case of a noisy Gaussian channel in the limit of unbounded key length and find improvements over all pre-existing continuous variable protocols in realistic regimes.
We propose **Holographic Session Links (HSL)** — a post-quantum communication protocol in which network routing, access control, and message authentication emerge from the algebraic resonance between communicating nodes' cognitive state polynomials, rather than from external certificates, address spaces, or permission systems. In HSL, a message from node
A to node
B is decryptable **if and only if** node
B's session polynomial
sB is algebraically resonant with the sender's session polynomial
sA. If resonance fails, the payload does not trigger an "access denied" response — it **collapses into irreversible thermodynamic noise** indistinguishable from the Ring-LWE error distribution. No routing table, no certificate authority, no firewall rule can prevent or simulate this collapse. The protocol extends **Holographic Session Spaces (HSS)** [Mazur, 2026a] from single-node process isolation to multi-node cognitive networks. Security is not a layer applied to communication — it is a **topological property of the communication space itself**.
