Systems, devices and methods are presented for providing controlled use of information stored publicly within the domain name system (DNS). Controlled use is established by storing encrypted data at the DNS servers and establishing trust, in the form of transfer of keying material, with requisite parties. The invention provides backward compatibility with existing DNS servers, in that, it provides for storage of encrypted data in existing resource records. The invention benefits from allowing storage in the DNS to be divided into both public and private classification, such that a user can identify and store certain public information that is available to all parties that have access to the DNS, while other information that has been classified as private is only available to parties which have established a trust. |
