Abstract: In some implementations, a device may receive a request to add a domain to a blockchain. The request may include data that indicates a public key associated with the domain and/or a unique identifier associated with the domain. The device may generate a domain information block, based on the request, that includes the public key associated with the domain and a blockchain identifier that is based on the unique identifier associated with the domain. The device may provide the domain information block to a set of blockchain nodes to add the domain information block to the blockchain.

Abstract: A device may receive, at an operating system, a request for a random number from an application. The device may provide a command to generate an entropy input, based on the request for the random number and through a driver that is isolated from the operating system, to a quantum random number generator that is isolated from one or more processors hosting the operating system. Accordingly, the device may receive the entropy input, from the quantum random number generator, using the driver, and may generate the random number based at least in part on the entropy input. The device may provide the random number to the application.

Abstract: A system described herein provide for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure (“PKI”) techniques or other techniques, using a secure distributed ledger (e.g., “blockchain”) system. A blockchain system may be utilized in lieu of a key escrow system in the exchange and/or providing of public keys in a Diffie-Hellman key exchange technique or other type of technique in which public keys are provided from one entity to another. A first entity may generate an asymmetric key pair that includes a public key and a private key, and may provide the public key to a blockchain system for retrieval by one or more other entities. For example, the entities may be engaged in a secure messaging session, in which messages are encrypted and may be decrypted using one or more keys, including the public key.

The network device may calculate a fourth hash value based on the OEM bootloader application. The network device may complete, when the third hash value and the fourth hash value are equivalent, a boot process for the network device.

Abstract: An Exhaust Gas Recirculation (EGR) effective flow diagnosis method includes: measuring an EGR gas temperature by an EGR gas temperature sensor under an EGR gas temperature rise condition of an EGR system on an intake line; determining the degree of the EGR gas temperature rise; and determining whether an EGR effective flow is excessive or insufficient according to the degree of the EGR gas temperature rise.

Abstract: A first user device may provide, to a provisioning device, a request for a subscriber identity module (SIM) swap that causes provisioning data to be provided to a first SIM card of the first user device and from a second SIM card of a second user device. The first user device may generate a first encrypted token based on a first identifier associated with the first SIM card. The first user device may provide, to the provisioning device, the first encrypted token and a user identifier. The first user device may selectively receive the provisioning data when the first encrypted token matches a second encrypted token generated by the second user device based on a second identifier associated with the second SIM card, or receive a message indicating that the first user device cannot be provisioned, when the first encrypted token fails to match the second encrypted token.
