DSrekordokká

DSrekordokká is a Hungarian term that translates to "DS records" or "DS record documents." In the context of digital signatures and public key infrastructure, a DS record is a specific type of DNS (Domain Name System) record that plays a crucial role in establishing trust and authenticity for domain names.

Essentially, a DS record acts as a delegation of signing authority. It links a domain name to its corresponding DNSKEY record, which contains the public key used to sign the DNS zone for that domain. This linkage is achieved through cryptographic hashing. The DS record itself contains a hash of the public key, along with other information like the key tag and algorithm.

When a user or system queries for a domain name, the DNS resolution process can verify the authenticity of the DNS records served for that domain by tracing a chain of trust back to the root zone. This chain of trust relies on DS records at each level of the DNS hierarchy. By verifying the DS record, one can be confident that the DNSKEY record received is indeed the correct one for the domain, and therefore, any DNS records signed with the corresponding private key are legitimate.

The implementation of DS records is a fundamental aspect of DNSSEC (DNS Security Extensions), a suite of extensions that adds security to DNS by enabling authentication of DNS data, protection against cache poisoning, and other man-in-the-middle attacks. DSrekordokká, as a concept, is therefore directly tied to the security and integrity of internet infrastructure.
