A terminal device verification method and an apparatus are provided. The method includes: A first network device receives a first message from a first terminal device. Then, the first network device verifies a pairing relationship between the first terminal device and a second terminal device. After the verification on the pairing relationship between the first terminal device and the second terminal device succeeds, the first network device sends a second message to the first terminal device, where the second message include first indication information, and the first indication information is used to indicate a pairing result of the first terminal device and the second terminal device. The pairing relationship between the first terminal device and the second terminal device is verified, so that the first terminal device and the second terminal device can be securely paired, to improve use security of the first terminal device and the second terminal device.

A blockchain-based privacy protection method for a CCN includes: executing, by a trusted AAC, an initialization algorithm to generate common parameters and a master key, generating a public key and a private key for each consumer and publisher, and randomly generating, by the trusted AAC, its own public key and private key; calculating a public key, and generating ciphertext and uploading the ciphertext to a CSP; performing transaction on-chaining; and during decryption, finding, by the consumer, transaction information of the content on the consortium blockchain, sending an interest packet based on the transaction information, and obtaining ciphertext CT through a storage address in the transaction information; generating, by the consortium blockchain, an access transaction based on access information of the consumer; sending the ciphertext CT to the consumer through a data packet; and locally decrypting, by the consumer, the ciphertext CT, and verifying correctness of the content.

A computer-implemented method for providing a system-specific secret to a computing system having a plurality of computing components is disclosed. The method includes storing permanently a component-specific import key as part of a computing component and storing the component-specific import key in a manufacturing-side storage system. Upon a request for the system-specific secret for a computing system, the method includes identifying the computing component comprised in the computing system, retrieving a record relating to the identified computing component, determining the system-specific secret protected by a hardware security module and determining a system-specific auxiliary key. Furthermore, the method includes encrypting the system-specific auxiliary key with the retrieved component-specific import key, thereby creating a auxiliary key bundle, encrypting the system-specific secret and storing the auxiliary key bundle and a system record in a storage medium of the computing system.

A location verification system according to an embodiment of the present disclosure includes a plurality of base stations located in respective preset areas and transmitting, to an adjacent mobile communication device, location verification information obtained by signing GPS information on the base stations with a private key. It is possible to expect an effect of re-verifying a location of a mobile communication device, such as a drone or a smart car, at a destination, when the mobile communication device has moved to the destination based on GPS information.

Disclosed herein are apparatuses and methods for verifying video authenticity using blockchain. An implementation may include receiving a video clip from a first source and generating a genesis block of a blockchain, wherein the genesis block includes the video clip, metadata of the video clip, and a first hash value of both the video clip and the metadata. The implementation includes distributing the blockchain to a plurality of nodes in a blockchain network. The implementation includes for each indication received of activity performed on the video clip to be recorded on the blockchain, verifying the activity and generating a new block on the blockchain recording the activity. The implementation includes receiving a modified version of the video clip, verifying an authenticity of the modified version based on each activity recorded in the blockchain, and in response to determining that the modified version is not authentic, generating an alert indicating inauthenticity.

A method for providing online security may include: (1) receiving, by a validation computer program executed by a trusted entity backend for a trusted entity, a call from a web browser executed on a customer electronic device browsing a webpage for an online entity, the call comprising an online entity identifier for the online entity and a session identifier, wherein the webpage for the online entity may include a hidden <iframe> comprising code that causes the web browser to execute the call; (2) confirming, by the validation computer program, that a cookie for the trusted entity may be stored on the customer electronic device; and (3) returning, by the validation computer program, a first value indicating that the customer electronic device is known to the trusted entity or a second value indicating that the customer electronic device is not known to the trusted entity based on the confirmation.

A trusted execution environment obtains a secure guest image and metadata to be used to start a secure guest. The metadata includes multiple parts and a plurality of integrity measures. A first part of the metadata includes one or more integrity measures of the plurality of integrity measures, and a second part of the metadata includes customized confidential data of the secure guest and one or more other integrity measures of the plurality of integrity measures. The trusted execution environment is used to verify at least one select part of the metadata using at least one integrity measure of the plurality of integrity measures of the metadata. Based on successful verification of the at least one select part of the metadata, the trusted execution environment starts the secure guest using the secure guest image and at least a portion of the metadata.

A trusted execution environment obtains an attestation request. The attestation request includes at least an attestation key. Based on obtaining the attestation request, one or more integrity measurements are computed, and the computing uses at least the attestation key. The one or more integrity measurements are provided to an entity, and the one or more integrity measurements are to be used to verify that a secure guest has been started using a selected secure guest image and selected secure guest metadata.

Disclosed are systems and methods that authenticate non-fungible tokens (“NFT”) and/or digital data represented by or pointed to by an NFT. In some implementations, authentication may be with respect to an existing NFT. In other implementations, authentication may be with respect to an NFT that is being created. The disclosed implementations may compare a candidate and/or candidate NFT data with existing NFTs and/or existing NFT data to determine if the candidate NFT and/or candidate NFT data is similar to other NFTs and/or other NFT data of another NFT, which may exist on any of many different blockchains.

An example method of performing interactive videogame verification using cryptographically protected transaction records includes: receiving, by a videogame server, from a first videogame client device, a first transaction record reflecting a first set of events associated with an interactive videogame session, wherein the first transaction record is cryptographically signed by a first private cryptographic key associated with the first videogame client device; receiving, from a second videogame client device, a second transaction record reflecting a second set of events associated with the interactive videogame session, wherein the second transaction record is cryptographically signed by a second private cryptographic key associated with the second videogame client device; and validating the first transaction record based on the second transaction record.
