KLV Packet Integrity

This MISB ST 0902 structural rule checks whether claimed MISMMS packets are structurally intact before profile-level checks are applied.

What This Test Does​

The rule validates:

  • BER length parsing
  • packet completeness across payload boundaries
  • checksum correctness when Tag 1 is present

✅ Pass Criteria​

The test passes when claimed MISMMS packets have valid BER lengths, can be reconstructed into complete packets, and pass checksum validation when checksums are present.

❌ Fail Criteria​

The test fails when BER length parsing is invalid, a packet is truncated or incomplete, or a present checksum does not match the packet payload.

Notes​

This rule combines the same evidence used by the MISB ST 0601 Raw KLV Decode and Checksum tests, but reports it as a single MISB ST 0902 packet-integrity check.
