D02-BP: Yes
Rationale
HDTN documents a userspace Linux implementation of BPv7/BPSec and TCPCLv4 with TLS 1.3, built with CMake, Boost, ZeroMQ and OpenSSL. Its IP/TCP transport uses the stock OS; no additional DTN kernel module or kernel rebuild is needed.
Assessment method
Documentary classification; no new runtime, interoperability or security experiment
Source context
Primary documents, published reports and versioned source review, 2026-10-15
Outstanding qualification
Enable BPSec and TLS support and provision keys, policies and NODE-ID certificates. This requirement finding does not qualify the separate ION F16/F21 witnesses together or certify their complete integration.
