摘要： Embodiments for device pairing using optical codes are described. One embodiment is a wearable device with an image sensor configured to capture an image including a first optical code from a first host device. The wearable device decodes the first optical code, and in response to the first optical code, initiates broadcast of a pairing advertisement. The host device displays a second optical code in response to the pairing advertisement, and the wearable device captures and processes the second optical code to determine a host pairing advertisement code. The wearable device then, in response to the second optical code, initiate broadcast of a second pairing advertisement including the host pairing advertisement code. In various embodiments, a secure wireless channel is then established and used for further secure communications.

摘要： In one embodiment, a method comprises: receiving, by a secure executable container executed by an endpoint device, a request from an originating entity for initiating a secure peer-to-peer communication with a second network entity via a secure data network, the originating entity and second network entity having established a two-way trusted relationship in the secure data network; processing, by the secure executable container, the request based on providing the originating entity sole and exclusive authority to control the secure peer-to-peer communication, including cryptographically secure termination and removal of the secure peer-to-peer communication from any network device in the secure data network; and initiating, by the secure executable container, the secure peer-to-peer communication by securely sending, to the second network entity via the secure data network, a secure peer-to-peer invitation for the second network entity to join the secure peer-to-peer communication.

摘要： System and method for masking secret polynomials for cryptography receives a secret polynomial function in a polynomial ring, which is masked with one or more masking polynomials in which at least some coefficients have a same value. An arithmetic operation is performed on coefficients of the masking polynomials with repeated coefficients to produce an output having integer values. A cryptographic operation is then performed with the output of the arithmetic operation.

摘要： Systems, methods, and computer program products are provided for quantum computing (QC) detection. An example QC detection system includes QC detection data generation circuitry that generates QC detection data. The QC detection system also includes cryptographic circuitry that distorts the QC detection data via a first post-quantum cryptographic (PQC) technique and generates a pair of asymmetric cryptographic keys including a public cryptographic key and a private cryptographic key. The cryptographic circuitry further generates encrypted QC detection data based on the pair of asymmetric cryptographic keys and destroys the private cryptographic key. The QC detection system further includes data monitoring circuitry that monitors a set of data environments for electronic information related to the encrypted QC detection data.

摘要： A computer-implemented method for transmitting and/or submitting digital content such as feedback for an entity to a blockchain is disclosed. This may be, for example, the Bitcoin blockchain. The method, which is implemented at a first node, includes: submitting, to the blockchain, a first transaction for committing a first quantity of tokens to transfer to a second node associated with the entity, the first transaction having a first output; generating a first content for submission to the blockchain; and submitting, to the blockchain, a second transaction that returns a second quantity of the committed first quantity of tokens to an address associated with the first node, the second transaction having the first output of the first transaction as an input, wherein the first content is used to unlock the first output of the first transaction.

摘要： A computing device includes at least one processor configured to determine a retrieved secret share from each of at least two secret share storage devices or media that are retrieved from at least two of a plurality of shareholders. The at least one processor is also configured to determine whether each respective retrieved secret share is one of the plurality of secret shares that were generated based on whether the respective hash of the respective retrieved secret share matches any hash in the list of hashes of the plurality of secret shares within the metadata. The at least one processor is also configured to, in response to determining that each retrieved secret share is among the plurality of secret shares that were generated, attempt to reconstitute a secret using retrieved secret shares from the at least two secret share storage devices or media.

摘要： A system and a method are provided for facilitating an account protection check through blockchain. The system and the method allow a service provider to utilize blockchain technology to validate the access request to various accounts. A public key and a private key are generated and recorded by a blockchain ledger that are used to access the accounts. A third-party server of a service provider requests a token from the system before the authentication process. If the credential set is in a locked status or unlocked status, at least one remote server of the system respectively relays an invalidation token or a validation token to the third-party server. If the invalidation token is relayed to the third-party server, the service provider does not go through the authentication process. If the validation token is relayed to the third-party server, the service provider proceeds with the authentication process as standard procedure.
