  • Patent number: 10097528
    Abstract: User data is aggregated across a plurality of electronic communication channels and domains. An online system initially authenticates a user for access to the online system over a network. The online system provides a user identifier for the user to an authentication service. The authentication service generates a non-repeatable challenge from the aggregated user data for the user identifier and provides the non-repeatable challenge to the online system. The online system provides the challenge to the user and receives a response from the user. The online system provides the response to the authentication service and the authentication sends a success or failure back to the online system based on the response to the challenge, and based on the success or failure the online system makes a final determination for authenticating the user for accessing to the online system.

  • Patent number: 10032020
    Abstract: This disclosure provides techniques for pooling and searching network security events reported by multiple sources. As information representing a security event is received from one source, it is searched against a central or distributed database representing events reported from multiple, diverse sources (e.g., different client networks). Either the search or correlated results can be filtered and/or routed according at least one characteristic associated with the networks, for example, to limit correlation to events reported by what are presumed to be similarly situated networks. The disclosed techniques facilitate faster identification of high-relevancy security event information, and thereby help facilitate faster threat identification and mitigation. Various techniques can be implemented as standalone software (e.g., for use by a private network) or for a central pooling and/or query service. This disclosure also provides different examples of actions that can be taken in response to search results.

  • Patent number: 10003576
    Abstract: Techniques for determining which resource access requests are handled locally at a remote computer, and which resource access requests are routed or “redirected” through a virtual private network. One or more routing or “redirection” rules are downloaded from a redirection rule server to a remote computer. When the node of the virtual private network running on the remote computer receives a resource access request, it compares the identified resource with the rules. Based upon how the identified resource matches one or more rules, the node will determine whether the resource access request is redirected through the virtual private network or handled locally (e.g., retrieved locally from another network). A single set of redirection rules can be distributed to and employed by a variety of different virtual private network communication techniques.

  • Patent number: 9959414
    Abstract: A method and apparatus is provided for the virtualization of cryptographic resources which enables memory speed encryption and decryption that is not bound by the speed at which processor resources can compute the result of a symmetric-key algorithm. This is achieved through a time-memory tradeoff via empty space at provisioning time. When implementing the apparatus, un-initialized memory is filled with the output of a symmetric-key algorithm uniquely keyed for the specific set of data that is going to be written to the provisioned area. Since the provisioning operation stores cryptographically structured data, rather than redundant data, plaintext that is xor'ed into memory is automatically encrypted and ciphertext that xor'ed into memory is automatically decrypted without the need for additional cryptographic computation. This reduced computation requirement enables cryptographic function to be implemented at the ends of communication, rather than the middle, and treated as a virtualized resource.

  • Patent number: 9942223
    Abstract: Automated device discovery of pairing-eligible devices for authenticating an unidentified user of a computing device is provided. When the user initiates a login on the computing device on which the user's identity is not known, an automated pairing-eligible device discovery authentication system interrogates a resource (e.g., subnetwork router, calendaring server) for identifying pairing-eligible devices that may be used as a second factor for authentication. A list of the pairing-eligible devices is presented to the user on the computing device. Upon selection of a pairing-eligible device to use as a second factor to verify the user's identity, the user's identity is determined, and a notification is sent to the selected pairing-eligible device for enabling the user to verify his/her identity using a second factor. Upon completion of an authentication challenge on the selected pairing-eligible device, authentication of the user is completed, and a signed token is sent to the computing device.

  • Patent number: 9942046
    Abstract: Cryptographic hashing circuitry such as mining circuitry used to mine digital currency may be formed on an integrated circuit. The hashing circuitry may include sequential rounds of register and logic circuitry that perform operations of a cryptographic protocol. A final hash output from the hashing circuitry may be checked using a difficulty comparison circuit to determine whether the hash output satisfies predetermined difficulty criteria. The difficulty comparison circuit may be configured as a hardwired comparison circuit having logic gates for checking only a subset of bits in the hash output. The comparison circuit may be adapted to change the number of bits that is checked based on a target number of bits for comparison set by the Bitcoin protocol. Candidate solutions found using the hardwired comparison circuit may then be fed to a host controller that checks the entire hash output to determine whether the candidate solution is valid.
