  • Using domain name system security extensions in a mixed-mode environment
    Patent number: 9544278
    Abstract: A method relates to generating, by a processing device executing a DNS resolver, a first domain name system (DNS) query comprising a DNS request generated from an application executing on the processing device to query a first DNS server serving a first DNS zone connected to the processing device via a public network, receiving, from the first DNS server, a first resource record comprising a DNS answer to the DNS query, a second resource record comprising a digital signature generated by signing the DNS answer with a first private key of the first DNS zone, a third resource record comprising a first public key for verifying the digital signature, and one or more files for validating a chain of trust of the first public key, determining, by the processing device in view of the one or more files, that the chain of trust of the first public key misses at least one of a trust anchor or a link in the chain of trust, and generating a second DNS query comprising the DNS request to query a second DNS server residing

  • Managing encrypted data and encryption keys
    Patent number: 8837734
    Abstract: A data module encrypts a first portion of a drive in a data center using a first encryption key. The data module encrypts the first encryption key using a second encryption key to obtain an encrypted encryption key. The data module stores the second encryption key in a first location and stores the encrypted encryption key in a second location that is separate from the first location and that is inaccessible from outside the data center.
