1. Introduction
The security of the ECC-GOST algorithm [RFC5933] has been slowly
diminishing over time as various forms of attacks have weakened its
cryptographic underpinning. Thus, the use of ECC-GOST is no longer
needed and is not recommend for use in DNSSEC [RFC4033] [RFC4034]
[RFC4035].
This document retires the use of ECC-GOST within DNSSEC.
1.1. Requirements notation
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
2. Deprecating ECC-GOST algorithms in DNSSEC
The ECC-GOST [RFC5933] algorithm MUST NOT be used when creating DS
records. Validating resolvers MUST treat DS records as insecure. If
no other DS records of accepted cryptographic algorithms are
available, the DNS records below the delegation point MUST be treated
as insecure.
The ECC-GOST [RFC5933] algorithm MUST NOT be used when creating
DNSKEY and RRSIG records. Validating resolvers MUST treat RRSIG
records created from DNSKEY records using these algorithms as
insecure. If no other RRSIG records of accepted cryptographic
algorithms are available, the validating resolver MUST consider the
associated resource records as Bogus.

3. Security Considerations
This document increases the security of the DNSSEC ecosystem by
deprecating algorithms that make use of older algorithms with ECC-
GOST derived uses.
4. Operational Considerations
Zone owners currently making use of ECC-GOST based algorithms should
immediate switch to algorithms with stronger cryptographic strengths,
such as those listed in the introduction. DNS registries [RFC8499]
should prohibit their clients to upload and publish ECC-GOST based DS
records.
5. IANA Considerations
IANA is requested to set the "DNSSEC Validation" of the "Digest
Algorithms" registry [DS-IANA] for ECC-GOST (3) to MUST NOT.
IANA is requested to set the "Recommended for DNSSEC Validation"
column of the DNS Security Algorithm Numbers registry [DNSKEY-IANA]
for ECC-GOST (23) to MUST NOT:
