  • Patent number: 11983547
    Abstract: System and methods discussed for automatically optimizing application and notification delivery based on user preferences and historical application usage. Applications that a user is likely to want to use at the present time or in the near future are displayed in an organizationally distinct way in an application catalog so they are easy to find and are pre-loaded on an application delivery server so they are available with minimal system lag caused by application loading processes. Application notifications are also optimized such that notifications that are likely to be relevant to users at the current time are identified and presented to them in an organizationally distinct way.

  • Patent number: 11979421
    Abstract: In some examples, a system for decorating network traffic flows with outlier scores includes a processor and a memory device to store traffic flows received from a network. The processor is configured to receive a set of traffic flows from the memory device and generate a tree model to split the traffic flows into clusters of traffic flows. Each cluster corresponds with a leaf of the tree model. The processor is further configured to generate machine learning models for each of the clusters of traffic flows separately. For a new traffic flow, the processor is configured to identify a specific one of the machine learning models that corresponds with the new traffic flow, compute an outlier score for the new traffic flow using the identified specific one of the machine learning models, and decorate the new traffic flow with the outlier score.

  • Patent number: 11968306
    Abstract: An integrated-circuit device comprises a physical-unclonable-function (PUF) unit, a secure module, and an interconnect system communicatively coupled to the PUF unit and to the secure module. The device transfers a PUF key from the PUF unit to the secure module, over the interconnect system. In order to do this, the secure module generates a random value. The secure module then sends the random value to the PUF unit. The PUF unit then performs a bitwise XOR operation between the received random value and the PUF key, to generate a masked value. The PUF unit then transfers the masked value over the interconnect system to the secure module. The secure module then unmasks the PUF key by performing a bitwise XOR operation between the received masked value and the random value.

  • Patent number: 11962686
    Abstract: Computer-readable media, methods, and systems are disclosed for handling intermediate data in connection with a database employing group-level encryption. Intermediate data is used during database operation and stored transiently such that the intermediate data is removed from memory upon database restart. To protect the privacy of the intermediate data, a random encryption key may be generated upon startup of a database instance. The random encryption key may be stored transiently. During database operation, the random encryption key may be used to encrypt and/or decrypt the intermediate data. The transient memory may be wiped upon database shut down such that the random encryption key is no longer accessible upon database restart.

  • Patent number: 11956273
    Abstract: Systems, methods, and computer-readable media for discovering trustworthy devices through attestation and authenticating devices through mutual attestation. A relying node in a network environment can receive attestation information from an attester node in the network environment as part of a unidirectional push of information from the attester node according to a unidirectional link layer communication scheme. A trustworthiness of the attester node can be verified by identifying a level of trust of the attester node from the attestation information. Further, network service access of the attester node through the relying node in the network environment can be controlled based on the level of trust of the attester node identified from the attestation information.

    Abstract: A malware profile is received. The malware profile comprises a set of n-tuples of attributes that describe one or more activities associated with executing a copy of a known malicious application that is associated with the malware profile. A set of one or more log entries is analyzed for a set of entries that matches the malware profile. Based at least in part on identifying the set of entries matching the malware profile, a determination is made that a host was compromised. In response to determining that the host has been compromised, a remedial action is taken with respect to the host.

  • Patent number: 11936784
    Abstract: Techniques are disclosed for enabling attested end-to-end encryption for transporting data between devices. In one example, a destination device receives a policy profile that includes an origination key and a destination key, and the origination key corresponds to a public transfer key of a source device. The destination device verifies the policy profile based on the destination key corresponding to a public transfer key of the source device. The destination device receives a signed encrypted data encryption key from the source device. The destination device receives encrypted data from the source device. The destination device verifies the signed encrypted data encryption key originated from the source device based on the signed encrypted data key being signed with a private attestation identity key that corresponds to a public attestation identity key of the source device. The destination device decrypts encrypted data using a private transfer key of the destination device.

  • Patent number: 11936774
    Abstract: A method (300) and system (1) of determining a common secret for two nodes (3, 7). Each node (3, 7) has a respective asymmetric cryptography pair, each pair including a master private key and a master public key. Respective second private and public keys may be determined based on the master private key, master public key and a deterministic key. A common secret may be determined at each of the nodes based on the second private and public keys. In one example, a node (3, 7) may determine the common secret based on (i) a second private key based on the node's own master private key and the deterministic key; and (ii) a second public key based on the other node's master public key and the deterministic key. The invention may be suited for use with, but not limited to, digital wallets, blockchain (e.g. Bitcoin) technologies and personal device security.

  • Patent number: 11930357
    Abstract: This invention is a system and method for verifying a sender of messages on a mobile network. Software on a cloud messaging service generates a public/private key pair. The private key is securely retained in a cloud wallet service and is accessible to a messaging cloud service (the trusted sender). The public key is shared with a subscriber device that receives messages from the messaging cloud service. The cloud messaging service receives an inbound message for the subscriber device from a trusted enterprise application via a secure connection. The cloud messaging service signs a special header to the message with its private key. When the message is received by the subscriber device, the public key resident on the device verifies the message header signed with the public key of the cloud messaging service thereby verifying the sender.
