RFC 9173, "Default Security Contexts for Bundle Protocol Security (BPSec)", January 2022

Source of RFC: dtn (int)

Errata ID: 7002
Status: Reported
Type: Editorial
Publication Format(s) : TEXT, PDF, HTML

Reported By: Ed Birrane

Section A.4.4.1 says:

This BCB has two targets: the payload block and BIB.

It should say:

This BCB has two targets: the payload block and BIB. 

NOTE: This example implies using a single Initialization Vector (IV) for
two separate encryptions (a BIB and the payload). This violates the 
requirement in Section 4.3.1 that the "initialization vector ... MUST 
NOT be reused for multiple encryptions using the same encryption key.". 
When using the BCB-AES-GCM security context containing a specified 
Initialization Vector, each BCB should have only one security target.  

Notes:

This is listed as "editorial" and not technical because the error appears in a non-normative portion of the document.
