  • Publication number: 20220092175
    Abstract: The disclosure relates to systems and methods for managing state using relatively small assistance from protected hardware. Obfuscated code segments may communicate with supporting protected hardware, store encrypted state values in main memory, and/or communicate via secure channels to secure platform hardware components. In various embodiments, consistent state may be achieved, at least in part, by computing secure tag information and storing the secure tag information in a secure and/or otherwise protected device register. Consistent with embodiments disclosed herein, the tag information may be used to derive keys used to encrypt and/or decrypt stored state information. Tag information may further be used in connection with verification operations prior to using the information to derive associated keys.

  • Publication number: 20220094536
    Abstract: This disclosure relates to, among other things, key generation systems and methods. Certain embodiments disclosed herein provide for generation of cryptographic keys based on one or more defined key generation rules. Key generation consistent with various aspects of the disclosed embodiments may increase the difficultly and/or cost of producing public keys and, by extension, discourage the generation of fake keys used in connection with a key flooding attack. In certain embodiments, generated keys and/or associated key generation rules may depend, at least in part, on associated binding data.

  • Publication number: 20210390189
    Abstract: This disclosure relates to, among other things, electronic device security systems and methods. Certain embodiments disclosed herein provide for protection of cryptographic keys and/or associated operations using both an operating system security service and a software-based whitebox cryptographic security service executing on a device. Leveraging operating system security services and software-based whitebox cryptographic security services may provide enhanced security when compared to using either service alone to protect cryptographic keys and associated operations. In additional embodiments, server-side cryptographic security solutions may be further used to enhance device security implementations.
