  • Systems and methods for secure processing with embedded cryptographic unit
    Patent number: 10430616
    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: December 29, 2017
    Date of Patent: October 1, 2019
    Assignee: Square, Inc.
    Inventors: Malcolm Ronald Smith, Kshitiz Vadera, Mark Phillip Zagrodney, Kevin Ka Wai Ng, Afshin Rezayee
