A Unified Firmware Framework for Cryptographic Acceleration

The present work is directed towards a unified firmware design architecture for cryptographic acceleration, enabling an FPGA-based development card to deliver enhanced performance for cyber-security applications. The firmware handles multiple link interfaces and communication channels for simultaneous cryptographic transactions while maintaining maximum throughput and minimum latency.The hardware accelerator includes eight processing channels bridged to UDP transport layer socket addresses. Its protocol layer allows multiple command queues to prioritize traffic, avoid overprovisioning, and enforce higher priority for performance-critical applications. Beyond single session management, the accelerator supports distributed and shared session management, while minimizing the logic resource footprint required for various cryptographic function implementations.The proof-of-concept is tested with a single 10 Gbps link using hashing functions, and validated for resilience under stress by exposing it to full data traffic load while monitoring processing channel performance and throttling capability.
