Abstract
Post-quantum cryptography (PQC) adds larger certificates and extra workload to the Transport Layer Security (TLS) handshake. In order to analyze the effect of that change on content delivery, a controlled testbed with conditions replicating a Content Delivery Network (CDN) is used. The system uses a standard X.509 certificate chain over TLS 1.3. It compares RSA with classical key exchange, RSA with hybrid key encapsulation mechanism (KEM), and Module Lattice-based Digital Signature Algorithm (ML-DSA) with hybrid KEM. The test harness generates and provides certificates and establishes TLS parameters. The test harness also supports mixed web workloads and records key metrics, including handshake time, page and object latency, throughput, and server CPU utilization. Experiments consist of hot and cold cache scenarios as well as new and keep-alive connections. Across the matrix, the session establishment cost increases under hybrid and PQC suites, while steady-state delivery is dominated by caching and connection reuse. CPU load is concentrated at the edge, and certificate chains remain within routine CDN limits. The experiments are conducted under reproducible, controlled network conditions using linux tc/netem.
