C04-I2: Yes
Rationale
NTCP2 AEAD Error Handling explicitly specifies probing-resistance behavior: on initial authentication failure, delayed closing with randomized timeout and read length, plus repeated-failure blacklisting. This credits a stated defense; ranges remain TBD and deployment efficacy is not established.
Assessment method
Documentary analysis
Source context
Primary specification / selected profile
Outstanding qualification
Pin an implementation and its timeout/read ranges, then evaluate probe distinguishability and false positives. The specification leaves those ranges TBD.
