looks like this:To avoid making your entire production DNS subject to dynamic DNS updates, then for each certificate domain you want:- In your main DNS infrastructure create a delegation:
_acme-challenge.<domain>. NS <your-nameserver>.
- Create a new zone
_acme-challenge.<domain>
on<your-nameserver>
, with an empty zonefile (just an SOA and NS record), writeable by the nameserver - Create a new TSIG key:
dnssec-keygen -r /dev/urandom -a hmac-sha512 -b 128 -n HOST <keyname>
- Enable dynamic updates on the
_acme-challenge.<domain>
zone with this key
e.g. for bind9:Bind Dynamic Update Key Generation 1
- Here's the quick and dirty: On BIND9 with a dynamic zone that's shared between views, doing a nsupdate, updating/creating/deleting a record will work fine if I query for that record from a client that falls into the same view I did the nsupdate from. Querying from a view that isn't the same as the one I used to nsupdate will throw NXDOMAIN (if adding a new record) or will show old record.

- In this post, I’m creating a key for use with nsupdate and configuring my BIND entry so that this key can be used only for amending TXT records. Creating a key Keys for this purpose can be generated with dnssec-keygen, which came as part of bind-tools-9.11.1 which I have installed on this server.

This is a secure approach because each host will have its own key, and hence can only obtain certificates for those domains you have explicitly authorized it for. Use /dev/random as an argument for dnssec-keygen for key generation to increase security further.Security AnalysisWe analyze the security of our protocols according to the requirements of contributions expressed in Section as follows. Analysis of Proposed Scheme 4.1. Strengthens the Confidentiality of Biological Information in the Recognition ProcessBecause only is transmitted and is compared during the biometric matching process, even if an attacker intercepts data during the process, he will be unable to decrypt the biometric data or impersonate an authorized user. Biometrics-based cryptographic key generation free. Reduces Vulnerability to Power Analysis Attacks, Fault-Based Cryptanalysis, and Replay AttacksSince only and are registered and stored, an attacker will be unable to use power analysis attacks or fault-based cryptanalysis to break the system. Strengthens the Confidentiality of Biometric Data StorageSince only and are registered and stored, even if an attacker accesses the registered biometric data stored in the biometric device, he will be unable to decrypt the biometric data or impersonate an authorized user.Bind Dynamic Update Key Generation 3
An alternative approach is to use CNAMEs to put all your dynamic updates into a single zone. You will need to modify the script:You then only need to create a single zoneacme.mydomain.com
which accepts dynamic DNS updates, but you will need to add static CNAMEs for_acme-challenge.<certname>
pointing at_acme-challenge.<certname>.acme.mydomain.com
for each certificate you want to issue.Bind Dynamic Update Key Generation 10
