Title: The Innovations of David Blacka
Introduction
David Blacka is an accomplished inventor based in Reston, Virginia. He has made significant contributions to the field of technology, particularly in the domain of DNS (Domain Name System) security. With a total of five patents to his name, Blacka's work has had a notable impact on how domain name resolution is managed and secured.
Latest Patents
One of Blacka's latest patents is titled "System and method for adding a whitelist entry via DNS." This invention outlines a method for adding a blacklisted site to a whitelist. The process involves generating at least one whitelisting query for an encoded domain, which includes a nonce, a hash, a blocked domain, and a static domain, all separated by a delimiter. The nonce serves as a unique identifier for the query, while the hash is a cryptographic representation of the user's IP address, a normalized timestamp, and the blocked domain. This query is sent to a first recursive DNS server, which creates a message containing whitelist information and forwards it to a second recursive DNS server.
Another significant patent by Blacka is "Systems and methods for pre-signing of DNSSEC enabled zones into record sets." This invention relates to the implementation of DNS policies desired by an administrator to govern domain name resolution with security extensions (DNSSEC). The DNS can generate answers to user queries based on these policies, storing variant answers labeled with a variant ID. By pre-signing and storing these answers, the system can respond to requests with enhanced responsiveness and security.
