As a summary, in this paper, we proposed an acceleration method of a client based
DNSSEC validation system in parallel with two full service resolvers. The first try of
domain name resolution took about 100-150 milliseconds and the results will be
cached on the end client if the validation successes. From the second try on the same
client the domain name resolution took 20-40 milliseconds. If we use the parallel query
to a cache DNS server, the first try with DNSSEC took 10 seconds if the validation was
performed from the root DNS server. Therefore, in the proposed system, the first try for
a domain name resolution will use the client based DNSSEC validation system.
On the other hand, the first try on other clients for the same domain name resolution,
it took 25-60 milliseconds. Accordingly, in the proposed system, the acceleration of the
first try of name resolution on other clients has been realized.
