  • Patent number: 10915464
    Abstract: A security system includes a physical unclonable function circuit, a write-in protection circuit, a memory, and a readout decryption circuit. The physical unclonable function circuit provides a plurality of random bit strings. The write-in protection circuit receives a write-in address and original data, and includes an address scrambling unit. The address scrambling unit generates a scrambled address by scrambling a write-in address according to a random bit string provided by the physical unclonable function circuit. The memory stores the storage data corresponding to the original data according to the scrambled address. The readout decryption circuit reads out the storage data from the memory according to the write-in address to derive the original data.

  • Patent number: 10904761
    Abstract: A communication method and system according to the present invention generates a unique cryptographically secure URI in response to receiving a user post. The user post and URI are stored temporarily. The URI is sent to an intended recipient. In response to a first instance of accessing the URI, the content is retrieved and sent to the intended recipient. The original uploaded content and URI are then deleted. In response to subsequent instances of accessing the URI, random content determined in part by a current environmental state of the communication, is returned. Recent subsequent instances can return thematically similar content.

  • Patent number: 10887334
    Abstract: A cybersecurity system and method utilizing SOUND reputation, where a set of reputations are associated with each actor on a network. The actors on a network may be users, hosts, applications, and the like. The associated reputations are aggregated and updated as new information about an actor's activity is reported according to a defined and modifiable protocol, or policy. The actor's activity may be reported by one or more threat sensors. The effect of a particular misbehavior can be tuned to match the needs of the specific network. When a bad actor's reputation sinks too low, the system can take whatever action is appropriate: reports can be sent, an operator can be notified, the offender can be cut off from the network, or the like.

  • Patent number: 10873468
    Abstract: In embodiments, an authentication server interfaces between a user device with a self-signed certificate and a verifying computer that accepts a user name and password. The user device generates a self-signed certificate signed by a private key on the user device. The self-signed certificate is transmitted to a verifying party computer over a network. A redirecting module redirects the self-signed certificate chain to an authentication server. The authentication server is also provided a user name, password and verifying computer address, which is stored in a password database by the authentication server, in association with the self-signed certificate. Subsequent communications intended for the verifying computer with the self-signed certificate are redirected to the authentication server, which looks up the associated user name and password and transmits the associated user name and password to the verifying computer.

  • Patent number: 10869195
    Abstract: Systems and techniques are provided for detecting rogue base stations and preventing malicious actors from intercepting and stealing data traffic from mobile devices through rogue base stations. Upon connecting to a newly detected base station for a cellular network service, a mobile device attempts to validate the cellular base station with a validation server before any data is transmitted over the new connection. If the mobile device does not receive a confirmation of validity from the validation server, the mobile device would identify the cellular base station as a rogue base station, disconnect from the rogue base station, and search for a valid base station for connection to the cellular network.

  • Patent number: 10862899
    Abstract: This specification describes techniques for performing cross-blockchain interactions. One example method includes generating, by a blockchain node in a first blockchain, a subscription request to a cross-chain interaction end between the first blockchain and a second blockchain. The blockchain node can then obtain a message from the second blockchain based on the subscription request, and subsequently perform an operation related to the obtained message. In some instances, the message obtained by the blockchain node is a message that is published in the second blockchain and satisfies subscription conditions of the blockchain node.
