  • Patent number: 12047406
    Abstract: Various embodiments include systems and methods to implement processing of web content for vulnerability assessments. A plurality of documents comprising web content may be obtained from multiple different web sources, and the documents may be parsed to determine a set of discrete document chunks. Parsing the documents includes determining whether a document satisfies a segmentation condition for segmenting the document into multiple discrete document chunks using a named-entity recognition system configured to segment the document based at least in part on a vulnerability identification. The discrete document chunks may be stored in a database, where vulnerability information is indexed such that each respective entry in the database corresponds to a respective vulnerability identification and a respective discrete document chunk.

    Abstract: Techniques are disclosed for inline security key exchanges between network devices. An example network device includes one or more processors and memory coupled to the one or more processors. The memory stores instructions that, upon execution, cause one or more processors to obtain a first payload key and obtain a path key. The instructions cause the one or more processors to encrypt a first payload of a first packet using the first payload key and insert the first payload key into first metadata of the first packet. The instructions cause the one or more processors to encrypt the first metadata using the path key and send the first packet to another network device.

  • Patent number: 12032676
    Abstract: This disclosure provides techniques for recovering a root key from measurement of a circuit function. In some embodiments, a checkpointing feature is used to periodically mark measurements of this function and thereby track drift in the value of the root key over the life of a digital device; the checkpointing feature permits rollback of any measurement of the function in a manner that negates incremental drift and permits recovery of the root key for the life of a device (e.g., an IC circuit or product in which the IC is embedded). This disclosure also provides novel PUF designs and applications.

    Abstract: Methods, systems and apparatus for quantum error correction. A layered representation of error propagation through quantum error detection circuits is constructed. The layered representation includes multiple line circuit layers that each represent a probability of local detection events in a quantum computing system associated with potential error processes in an execution of a quantum algorithm. To construct the layered representation, potential detection events associated with each potential error process occurring at quantum gates in the quantum circuit are determined. Lines are associated with each potential error process, the lines each connecting a potential detection event associated with the potential error process to another potential detection event associated with the same potential error process or a boundary of the quantum circuit. Similar lines are merged and used to construct unique line circuit layers.

  • Patent number: 11811533
    Abstract: In order to acknowledge uplink frames transmitted from end devices to server equipment, the server equipment allocates the end devices to groups and to subgroups. The addresses of the end devices are constructed so as to identify the groups and subgroups to which said end devices belong. The server equipment carries out mass acknowledgements by group, by broadcasting a message wherein each subgroup of said group is associated with the same item of information acknowledging, or not, said uplink frames of all the end devices of said subgroup. The mass acknowledgement further includes information representing an estimated instant of next transmission of a mass acknowledgement for said group. The server equipment acknowledges, in unicast mode, the uplink frames received that have not been acknowledged by the mass acknowledgement.

  • Patent number: 11805107
    Abstract: The disclosed embodiments disclose techniques for extracting encryption keys to enable monitoring services. During operation, an encrypted connection is detected on a computing device. A monitoring service harvests an encryption key for this encrypted connection from the memory of a computing device and then forwards the encryption key to an intercepting agent in an intermediate computing environment that intercepts encrypted traffic that is sent between the computing device and a remote service via the encrypted connection.

  • Patent number: 11792158
    Abstract: A service monitors password and username use while maintaining username and password privacy by receiving a hash of a username, a hash of a password, and a host name and comparing the received hashes against a database of associated host names and hashes of usernames and passwords. When the comparison determines that the hash of the new password meets certain conditions, e.g., no hash in the database matches the hash of the new password, then the new password may be allowed and the service informs the security component accordingly.

  • Patent number: 11792003
    Abstract: Distributed storage system and method for transmitting storage-related messages between host computers in a distributed storage system uses a handshake operation of a first-type communication connection between a source data transport daemon of a source host computer and a target data transport daemon of a target host computer to derive a symmetric key at each of the source and target data transport daemons. The two symmetric keys are sent to a source data transport manager of the source host computer and to a target data transport manager of the target host computer. The source and target data transport managers then use the same symmetric keys to encrypt and decrypt storage-related messages that are transmitted from the source data transport manager to the target data transport manager through multiple second-type communication connections between the source and target data transport managers.

  • Patent number: 11784790
    Abstract: Keystream generators for secure data transmission, the keystream generators being operated in counter mode, against repeated or improper generation of an already generated keystream and to protect the data transmission against repeated use of a keystream, so-called reuse are provided. The keystream generator is operated, with respect to realization options, selectively in one of two operating modes, an encryption operating mode and a decryption operating mode. In the encryption operating mode, a keystream generated on the basis of a first control data set is used to encrypt data, in particular payload data, to form cipher-data, the product of ciphered data or payload data. In the decryption operating mode, a keystream generated on the basis of a second control data set is used to decrypt the cipher-data. The keystream is output only if the generation of the keystream from the encryption of a counter value of the keystream generator operated in counter mode with a block cipher key is error-free.
