  • Patent number: 12003626
    Abstract: A method of generating a nonce includes measuring a TOA and a corresponding first or second state value of a plurality of first photons, wherein respective ones of the plurality of first photons are entangled with respective ones of a plurality of second photons in a first basis, which is time, and entangled in a second basis. A first ordered list of the measured TOAs of the plurality of first photons is generated. A TOA and a corresponding first or second state value of the plurality of second photons are measured. A second ordered list of the measured TOA of the plurality of second photons is generated. TOA matches between the first ordered list and the second ordered list are determined. The first or second state values that correspond to the determined TOA matches between the first ordered list and the second ordered list are determined. A shared secret random number is determined using the first or second state values that correspond to the determined TOA matches.

  • Patent number: 11997134
    Abstract: This disclosure describes a technique to determine whether a client computing device accessing an API is masquerading its device type (i.e., pretending to be a device that it is not). To this end, and according to this disclosure, the client performs certain processing requested by the server to reveal its actual processing capabilities and thereby its true device type, whereupon—once the server learns the true nature of the client device—it can take appropriate actions to mitigate or prevent further damage. To this end, during the API transaction the server returns information to the client device that causes the client device to perform certain computations or actions. The resulting activity is captured on the client computing and then transmitted back to the server, which then analyzes the data to inform its decision about the true client device type.

  • Patent number: 11985245
    Abstract: Disclosed are an access security system using a security card and a mobile terminal, and a security method for same. The present disclosure configures a mutual security function for storing an encrypted public key in a security card (E-card), and storing a private key, which can decrypt the encrypted public key, in a mobile terminal. Accordingly, a security function that is strengthened to the next level is achieved which: only allows secure access at an entrance by means of a mutual certification procedure through an NFC connection between the security card and the mobile terminal; increases the security efficiency of access management while preventing the security of a secure server from being neutralized by an information leak that has occurred due to the loss, theft, hacking, duplication, or the like of the security card; and in particular, fundamentally prevents abnormal connections by third parties to IoT equipment that can be connected to the secure server as a result of the neutralization of security.

  • Patent number: 11974129
    Abstract: A token-based security risk assessment service for multi-factor authentication (MFA) is described. An enterprise may utilize the security risk assessment service, and a telecommunication service provider may provide the security risk assessment service as a network-based service. The security risk assessment service may be configured to monitor identifiers (IDs) of elements associated with users associated with an enterprise to determine if any have changed. Any changes may be factored into an adjustment to the user's security profile. Furthermore, the enterprise can utilize the security risk assessment service to implement a token-based MFA scheme where Short Message Service (SMS) is used as an authentication factor.

  • Patent number: 11968298
    Abstract: The present invention relates to methods for secure computation and/or communication. Entangled photons (118) are generated such that each participating party receives a series of optical pulses. Each party has private information (110, 112) which are never transmitted through public or private communication channels. Instead, each party converts their respective private information (110, 112) into measurement bases via an encryption process (114, 116) which are then applied to the entangled photons (118). After the measurement process, e.g., quantum frequency conversion (122, 124), reference indices are announced (124, 126) so that computation can be performed (128) without revealing the private information directly or indirectly.

  • Patent number: 11960618
    Abstract: A computer implemented method searches data. A number of processor units generates a candidate search result using an index for a data source in response to a search query by a user, wherein the candidate search result comprises files accessible by the user based on access control information in the index. The number of processor units generates a completed search result with a set of the files from the candidate search result having a confidentiality level less than or equal to a threshold confidentiality level. The number of processor units determines whether the user has access to a file in the candidate search result in which the file has the confidentiality level greater than the threshold confidentiality level for the data source. The number of processor units adds the file to the completed search result in response to the file being accessible by the user in the data source.

  • Patent number: 11956240
    Abstract: One example method includes providing temporary access to a computing system and to providing temporary access as a service. The features of a temporary access can be defined by an entity and a user may be able to obtain a token that includes these features, which may be embedded in the token as claims. The user's access is then controlled in accordance with the embedded claims. The temporary access as a service can be federated. The token may include trust levels and tolerance limits. Further, aspects of the temporary access can be monitored and/or changed. Adjustments to trust levels can be automated or manually performed. Further trust for specific users can be gained or lost over time based on at least previous accesses.

  • Patent number: 11947657
    Abstract: An Identity and Access Management Service implements persistent source values PSVs) for assumed identities. A source value (e.g., an original identifier of an entity) is persisted across assumed identities, facilitating identification of entities (users or applications) responsible for actions taken by the assumed (e.g., alternative) identities. The Manager receives a request to assume an identity. The request includes the entities current credentials and a PSV. The current credentials are authenticated and a persistent source value policy may be relied on to determine whether and/or how to grant the assumed identity. The PSV may be copied from credentials in the request in order to be included in the credentials for the requested identity that the Manager provides in response to the request. Use of the requested credentials, including the PSV, to access services or resources may be logged, the logs including the PSV from the request to assume the identity.

  • Patent number: 11943336
    Abstract: A method of encrypting and decrypting multiple individual pieces or sets of data in which a computing device randomly selects a group of seeds that it then uses to generate irrational numbers. Sections of the generated irrational numbers can be used as one-time pads or keys to encrypt the corresponding data sets. Intended recipients can then reverse the process using their allowed keys to access data for which they have authorization.

  • Patent number: 11930101
    Abstract: A system and method are provided for mitigating key-exhaustion attacks in a key exchange protocol. The method includes computationally confirming an exchange of key bits has provided fresh shared key material before information theoretically confirming the exchange of key bits has provided fresh shared key material, while maintaining synchronization between messaging parties. In one implementation, maintaining synchronization includes updating keys in between each post-processing message session and managing a local state of each messaging party in the key exchange protocol prior to sending a next post-processing message. In another implementation, maintaining synchronization includes hiding a message containing the information theoretic authenticator by executing a decoy authentication process, prior to using an information theoretical key.
