- Google's PSP Security Protocol for TCP encryption is ready for the Linux 6.18 kernel.
- PSP underwent 13 rounds of review and was tested with PSP-capable CX7 NICs.
- PSP is an encryption layer over IP, designed for simplicity, functionality, and scalability in data centers.
- Google has been using PSP internally and open-sourced its architecture in 2022.
- Initial support includes only the NVIDIA-Mellanox MLX5 network driver.
- PSP can work in multiple modes, including as a TLS replacement with superior offload characteristics.
- The protocol integrates with TCP similarly to TLS, focusing on offload-centric features.
