DH-DNS plays a critical role in securing online communications through the combined use of Diffie-Hellman Key Exchange and Domain Name System Security Extensions. Diffie-Hellman Key Exchange enables secure key distribution over insecure communication channels, crucial for establishing encrypted connections. On the other hand, DNSSEC strengthens the authenticity and integrity of DNS responses, safeguarding against domain name hijacking and unauthorized tampering. By leveraging both technologies, DH-DNS enhances the encryption process and ensures the privacy and confidentiality of online data transmissions. The adoption of DH-DNS is vital in protecting sensitive information, preventing eavesdropping, and mitigating potential security breaches.#26#
