Mark Philip Zagrodney has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Systems and methods for secure processing with embedded cryptographic unit
    Patent number: 9886596
    Abstract: Processor system with a general purpose processor and a cryptographic processor dedicated to performing cryptographic operations and enforcing the security of critical security parameters. The cryptographic processor prevents exposure of critical security parameters outside the cryptographic processor itself, and instead implements a limited scripting engine, which can be used by the general purpose processor to execute operations that require the critical security parameters.
    Type: Grant
    Filed: June 25, 2015
    Date of Patent: February 6, 2018
    Assignee: Square, Inc.
    Inventors: Malcolm Ronald Smith, Kshitiz Vadera, Mark Philip Zagrodney, Kevin Ka Wai Ng, Afshin Rezayee
