SUBRAHMANYAM VENAKATA VISHNUVAJHALA 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).

  • Patent number: 11783091
    Abstract: Disclosed are various embodiments for executing entity-specific cryptographic code in a cryptographic coprocessor. In one embodiment, an exemplary method comprises receiving encrypted code that includes implementing a cryptographic algorithm from a service via a network, wherein the encrypted code further includes a symmetric encryption key; decrypting, by a cryptographic coprocessor, the encrypted code; executing, by the cryptographic coprocessor, the decrypted code to generate a cryptogram including information encrypted using the cryptographic algorithm and the symmetric encryption key; and sending the cryptogram to the service via the network.
    Type: Grant
    Filed: May 20, 2022
