  • Patent number: 11601260
    Abstract: Systems and methods relating to the encryption and decryption of messages to be sent through a communications link. The system and method uses a random data source at the receive and transmit sides, along with a trusted random sampler that produces correlated random samples from the random data source to be used at the send and receive sides. At the transmit side, the correlated random sample is used to generate a symmetric key as well as a ciphertext. The symmetric key is then used to encrypt the message. The ciphertext is transmitted, along with the encrypted message, to the receive side. The receive side then uses the ciphertext, along with its own correlated random sample, to recover the symmetric key. The symmetric key is then used to decrypt the encrypted message.

  • Patent number: 11568044
    Abstract: Example embodiments provide methods, apparatuses, systems, computing devices, and/or the like for vetting USB device firmware via a USB-specific firmware analysis framework. In one example, a method is provided for analyzing firmware of a Universal Serial Bus (USB) device. The example method includes steps of receiving a firmware image extracted from the USB device, identifying signatures from the firmware image relating to USB operation, and building an expected model of operation of the USB device using the identified signatures and a database of operational information regarding USB devices. The example method further includes the steps of generating a recovered model of operation of the USB device based on the firmware image and the identified signatures, and comparing the recovered model of operation with the expected model of operation to identify unexpected or unknown behaviors. The example method may further include generating a report comprising the identified unexpected or unknown behaviors.

  • Patent number: 11550913
    Abstract: Aspects of the disclosure describe methods and systems for performing an antivirus scan using file level deduplication. In an exemplary aspect, prior to performing an antivirus scan on files stored on at least two storage devices, a deduplication module calculates a respective hash for each respective file stored on the storage devices. The deduplication module identifies a first file stored the storage devices and determines whether at least one other copy of the first file exists on the storage devices. In response to determining that another copy exists, the deduplication module stores the first file in a shared database, replaces all copies of the first file on the storage devices with a link to the first file in the shared database, and performs the antivirus scan on (1) the first file in the shared database and (2) the files stored on the storage devices.

  • Patent number: 11522674
    Abstract: Embodiments of the invention relate to symmetric encryption that converts plain text to Diophantine equations, i.e. cipher text, and creates a symmetric key which is held by a sender (or encryption apparatus) and a recipient (or decryption apparatus). The key is used by the decryption apparatus to decrypt the Diophantine equations, and convert them to original plain text. Particularly, undecidable encryption and artificial intelligence (AI) are employed in combination. More particularly, the AI would exclude any class of Diophantine equations which has been solved or deciphered without key, or known to be solvable. In the event certain classes of Diophantine equations are solved in the future, the AI will exclude the use of these solved or solvable classes of Diophantine equation in encryption.
