Multi-tenant public cloud tenants nowadays have the increasing demand for cryptographic service to secure their applications. Virtio-Crypto device proposed to the community as a cloud-friendly virtual device, lacks a high-performance acceleration method in both frontend and backend.
To solve this challenge, we propose an all-inclusive Virtio-Crypto acceleration solution based on DPDK and DPDK Cryptodev Framework. The solution is composed of a backend DPDK vhost-crypto extension as well as a frontend DPDK Virtio crypto PMD. We will present this solution in detail including the utilization of the techniques such as burst-operation, polling mode Virtio queue access, zero-copy, and DPDK Cryptodev Framework including scheduler PMD, and the significant performance gain achieved. We will also describe the possible use cases this solution may help achieve in the cloud-based crypto applications.
