C03-HP: No
Rationale
Established HIP UPDATE signaling carries control parameters such as sequence/acknowledgment and locator updates outside ESP payload encryption. HIP_MAC and signatures authenticate these messages without concealing their control contents.
Assessment method
Documentary mechanism inventory; no traffic-analysis experiment
Source context
Primary packet-format, signaling and padding specifications
Outstanding qualification
This finding uses post-establishment signaling, not bootstrap or merely an exposed outer framing bit. ESP still encrypts user payload. No outer control-encryption tunnel is selected.
