Subject: [TLS] [Technical Errata Reported] RFC8422 (5703)

From: RFC Errata System <[email-masked]>
Date: Tue, 23 Apr 2019 10:05:34 -0700 (PDT)

The following errata report has been submitted for RFC8422,
"Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS) Versions 1.2 and Earlier".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5703

--------------------------------------
Type: Technical
Reported by: Frank Theinen <[email-masked]>

Section: 5.10.

Original Text
-------------
All RSA signatures must be generated and verified according to
   Section 7.2 of [RFC8017].

Corrected Text
--------------
All RSA signatures must be generated and verified according to
   Section 8.2 of [RFC8017].

Notes
-----
Section 7.2 of RFC 8017 describes the RSAES-PKCS1-v1_5 encryption scheme. Section 8.2 of RFC 8017 describes the RSASSA-PKCS1-v1_5 signature scheme. The original text contradicts the natural expectation and is probably wrong. If it was intended, there should have been a thorough explanation (like in the well-known case of IKEv1 using the encryption scheme for signing).

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
