  • Patent number: 11500785
    Abstract: Disclosed are devices, systems, apparatus, circuits, methods, products, and other implementations, including a method that includes obtaining, during execution of a process associated with a particular privilege level, data content from a memory location, and determining by a hardware-based detection circuit whether the data content matches at least one of one or more token values, with the one or more token values stored in one or more pre-determined memory locations, and with access of any of the pre-determined one or more memory locations indicating a potential anomalous condition. The method further includes triggering, in response to a determination that the data content matches the at least one of the one or more token values, another process with a higher or same privilege level as the particular privilege level associated with the process, to handle occurrence of a potential system violation condition.
    Type: Grant
    Filed: September 7, 2018
    Date of Patent: November 15, 2022
    Assignee: The Trustees of Columbia University in the City of New York
    Inventors: Lakshminarasimhan Sethumadhavan, Kanad Sinha

  • Patent number: 10237059
    Abstract: Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a method that includes receiving a block of information from non-processor memory at an interface between the non-processor memory and processor memory comprising two or more processor memory levels, determining whether the block of information received from the non-processor memory at the interface corresponds to encrypted instruction code, and decrypting the block of information at the interface between the non-processor memory and the processor memory for storage in one of the two or more levels of the processor memory in response to a determination that the received block of information corresponds to the encrypted instruction code. The block of information is stored at the one of the two or more levels of the processor memory without being decrypted when the received block of information is determined to correspond to data.
