Abstract: Implementations of the present specification disclose a consensus verification method, apparatus, and device. In the implementations of the present specification, for each piece of service data, if first consensus verification on the service data fails, a first node determines whether the service data satisfies a predetermined retry condition instead of directly considering the service data to be invalid. If the predetermined retry condition is satisfied, then the service data is stored as service data to be retried. The first node can perform the first consensus verification on the service data to be retried in response to determining that a predetermined retry execution condition is triggered.

Abstract: The present disclosure is directed to methods and apparatus that manage the flow of traffic. Methods and systems consistent with the present disclosure may allow biometric information of individuals to be collected when access privileges associated with particular individuals are validated or updated.

Such authorization rules may require proposed signal light timing changes to be approved by a supervisor before a proposed change is implemented. Methods and systems consistent with the present disclosure may also cause components within a control cabinet to be disabled or disconnected when a signal light control cabinet is accessed by unauthorized persons.

Abstract: Various embodiments of the invention implement countermeasures designed to withstand attacks by potential intruders who seek partial or full retrieval of elliptic curve secrets by using Various embodiments of the invention implement countermeasures designed to withstand attacks by potential intruders who seek partial or full retrieval of elliptic curve secrets by using known methods that exploit system vulnerabilities, including elliptic operation differentiation, dummy operation detection, lattice attacks, and first real operation detection. Various embodiments of the invention provide resistance against side-channel attacks, such as simple power analysis, caused by the detectability of scalar values from information leaked during regular operation flow that would otherwise compromise system security. In certain embodiments, system immunity is maintained by performing elliptic scalar operations that use secret-independent operation flow in a secure Elliptic Curve Cryptosystem.

Abstract: There is provided a new IWF SMC procedure for establishing security association between an MTC UE (10) and an MTC-IWF (20). The MTC-IWF (20) sends to the UE (10) at least an algorithm identifier which instructs the UE (10) to select one of algorithms for deriving a root key (K_iwf). The UE (10) derives the root key (K_iwf) in accordance with the selected algorithm, and derives at least a subkey for checking the integrity of messages transferred between the UE (10) and the MTC-IWF (20) by using the derived root key (K_iwf). The UE (10) protects uplink messages transmitted to the MTC-IWF (20) with the derived subkey. The MTC-IWF (20) protects downlink messages transmitted to the UE (10) with the same subkey derived at a core network.

Abstract: A system, method, and computer program product to renewably prevent traitors in a broadcast encryption system from re-using compromised keys. A license agency assigns individual receivers a set of Sequence Keys preferably at manufacture, and assigns Sequence Key Blocks (SKBs) to protected content files to be distributed. The files may be distributed on prerecorded media and typically include several file modifications. The particular modifications in a pirated version of a file can help identify which traitors contributed to its theft. SKBs assigned to new files distributed after traitors have been identified cannot be usefully processed using the compromised keys employed in previous content piracy. Innocent receivers that happen to have compromised key(s) in common with traitors can use a replacement uncompromised Sequence Key from the set to usefully decrypt content. Traitors will however step through all their Sequence Keys without reaching one that will work.

Abstract: A blockchain database employs cryptography and other methods to implement and protect a distributed, publicly-amendable ledger. Transactions in a blockchain ledger are intentionally anonymous; however, there are cases where it would be useful to be able to verify or disprove a claim of identity of a contributor of a blockchain transaction. Biometrics can be used to link a human being to digital information using their unique physical traits in a way that is analogous to a handwritten or digital signature. An exemplary embodiment disclosed herein describes methods to create and store data in a blockchain transaction such that it can be used in the future to biometrically verify the identity of the contributor of the transaction, and use encoded biometric data to determine whether the blockchain transaction was created or not created by a particular individual.

Abstract: A method is provided for protecting a trained machine learning model that provides prediction results with confidence levels. The confidence level is a measure of the likelihood that a prediction is correct. The method includes determining if a query input to the model is an attempted attack on the model. If the query is determined to be an attempted attack, a first prediction result having a highest confidence level is swapped with a second prediction result having a relatively lower confidence level so that the first and second prediction results and confidence levels are re-paired. Then, the second prediction result is output from the model with the highest confidence level. By swapping the confidence levels and outputting the prediction results with the swapped confidence levels, the machine learning model is more difficult for an attacker to extract.

In response to receiving the request based on the mapping relationship, a certificate ID of an existing certificate that corresponds to the received device ID and satisfies the identity verification requirement is retrieved. In response to retrieving the certificate ID, a certificate response to the client including the retrieved certificate ID is sent.
