Fast and Secure: DPDK Meets Confidential Computing

Explore a technical conference talk that delves into the integration of DPDK (Data Plane Development Kit) with Confidential Computing technologies. Learn how modern Confidential Virtual Machine (CVM) technologies like AMD SEV, Intel TDX, and ARM CCA enable secure cloud service deployment without requiring trust in cloud providers. Discover the unique challenges faced when implementing high-performance I/O applications in confidential computing environments, including shared hugepage management, DPDK library optimization, and hardware-specific CVM restrictions. Examine practical solutions for deploying DPDK applications in CVMs, including kernel modifications for private/shared memory differentiation, CVM-aware memory management optimizations, and the development of an abstraction layer to handle platform differences. Understand the design trade-offs and future development possibilities for combining high-performance packet processing with confidential computing security features.
