Cryptographic Performance and Scalability Questions

Designing cryptographic components and systems for performance and scale while preserving security. Topics include optimizing throughput and latency, selecting algorithms and parameters with performance in mind, hardware acceleration and processor instruction support for cryptographic primitives, batching and parallelization strategies, trade offs between key sizes and performance, handshake and session optimization for protocols, resource constraints for embedded and mobile devices, benchmarking and profiling, and planning for operational scale including hardware security module capacity and key management throughput.
