JPRS Deploys DNSSEC in the JP Domain Name Service

- To Contribute to the Internet by Improving the Security of JP Domain Names -

On January 16, Japan Registry Services Co., Ltd. (JPRS: head office at Chiyoda-ku Tokyo; President: Koki Higashida) completed the release of DNSSEC feature in the JP domain name service in order to improve the security of JP domain names.

DNSSEC is a security extension of DNS that uses digital signatures through public key cryptography. With this release, registrants of JP domain names can register the registrants' key information to the JP zone, which in turn enables Internet users to validate the response with its digital signature(s) and to detect bogus DNS responses. Consequently, the release will considerably reduce the risks including phishing, etc.

JPRS considers that DNSSEC can effectively prevent the security threats caused by bogus DNS responses. Based on this understanding, it has introduced the specifications in Japan and performed testbeds and demonstrations in cooperation with the DNS operators at home and abroad with an aim to deploy DNSSEC. On October 17, 2010, JPRS started signing the JP zone and registered the key information (DS resource record) of the JP zone in the root on December 10, 2010. After confirming that the JP zone was properly validated by the root zone key as a trust point, and that existing DNS infrastructures were not adversely affected, JPRS has completed the deployment of DNSSEC in the JP domain name service this time.

Along with this service launch, JP Registrars explained their plan with regard to DNSSEC deployment as follows.

Internet Initiative Japan Inc.

Internet Initiative Japan Inc. (IIJ) announced that it will upgrade all of its DNS-related services, such as the DNS Outsourcing Service, to be compatible with DNS Security Extensions (DNSSEC).

Additionally Domain Management Service can perform registration of DS (delegation signer) for top-level DNS servers IIJ will continue to expand the use of DNSSEC enabled services in the future.
