Abstract

The invention relates to a method for updating key-signing keys and zone-signing keys in domain name system security extension (DNSSEC). The method includes the following steps that: in a DNS region, new key-signing keys and new zone-signing keys are added to a DNSKEY resource record set, and the new key-signing keys and original key-signing keys are utilized to sign the DNSKEY; the new zone-signing keys are utilized to sign all resource record sets, and the new key-signing keys or DS records are submitted to the parent domain of the DNS region; the DNS region signed by the new zone-signing keys is transmitted to a slave server of the DNS region, and the DS records are transmitted to a slave server of the parent domain; and original zone-signing keys are deleted from the DNSKEY, and the new key-signing keys are utilized to re-sign the DNSKEY resource record set, and the original key-signing keys are deleted from the DNSKEY, and the new key-signing keys are utilized to re-sign the DNSKEY resource record set.

Description

technical field [0001] The present invention relates to a method for renewing keys, in particular to a method for renewing key signature keys and zone signature keys used in Domain Name System Security Extensions (DNSSEC for short). Background technique [0002] The Domain Name System (DNS for short) is a hierarchical distributed database that contains a series of records, including names, IP addresses, and host information. DNS is a set of protocols and services that allow users to use hierarchical user-friendly names instead of IP addresses when looking up network resources. When the DNS client sends an IP address query request to the DNS server, the DNS server can search the required IP address from its database to the DNS client. This process by which the DNS server finds the client's IP address in its database is called "host name resolution." [0003] In order to improve query efficiency, DNS adopts a cache mechanism to store the latest queried records in the cache a...
