摘要： A method is disclosed. The method includes a user device storing a message data template comprising a plurality of data fields. A multi-record message may be generated using the message data template in response to an interaction between the user device and an access device. To generate the multi-record message, the user device may increment a counter stored on the user device to produce a counter value, and generate a dynamic cryptogram. The user device may additionally retrieve a credential. The counter value, the dynamic cryptogram, and the credential may then be incorporated into the plurality of data fields of the message data template to form the multi-record message. The multi-record message may be transmitted to the access device, where the access device forwards the multi-record message to an authorization computer to authorize or deny the interaction.

摘要： The present invention is a protocol and platform which supports real-time reconciliation, balance confirmation and audits across multiple stakeholders and their ledgers. The platform is built on Application layer Atomic Multicast protocol, the platform ensures complete transparency and immutability of any transaction, from transaction initiator to the consumer also cutting costs. Further, the platform's Distributed Ledger offers near-Zero-latency with transaction cost while being able to support over very high throughput and scalability, thus breaking all barriers and challenges in scaling, latency and atomicity. Further, the invention can reduce and eliminate the risk of human error and fraud. The invention is an end-to-end quantum secure, thus eliminating any possibility of breaching data.

摘要： A method for tracking communication, comprising: receiving a notification pertaining to a communication protocol and associated with a communication between an initiating device and a receiving device; implementing a security protocol embedded within the communication protocol by: establishing, on a distributed ledger, a smart contract for tracking communication along a channel to a subsequent operator of a sequence of operators forming a communication path between the initiating and receiving device, the channel being at least a segment of the communication path, and registering the smart contract with a governing contract associated with an originating operator in communication with the initiating device over a local channel and configured to govern communication along the communication path; and transferring the notification to the subsequent operator along the at least segment of the communication path.

摘要： According to an embodiment, a sender configured to participate in an in-vehicle network. The sender is configured to receive a request for transmitting a payload and to generate, in response, a first header in the transport and/or network layer. It is further configured to access a key K of k bytes length and to generate an authentication tag using the key K and at least the first header as additional authentication data. The authentication tag serves to indicate an authenticity of a first frame on the transport and/or network layer as original frame sent from the sender to a receiver. The sender is further configured to generate the first frame comprising the first header, a transport layer payload and the authentication tag and to forward the first frame to the data link layer, the data link layer to generate a second frame on the data link layer and to emit the second frame to the in-vehicle network.

摘要： A method of securing electronic computer files includes having a client-based application running in the background with a kernel extension and a communication channel over a network to a server. The client app. can intercept an interprocess communication for opening a file and then collect a swath of fingerprint information about the requesting process and the state of the computer. The fingerprint information is sent to the server, optionally through a Signal Protocol message hidden by steganography in an image. Based on the fingerprint information, the server sends a key and/or a command back, optionally through steganography, to the client. The file is then accessed and decrypted—or accessed and not decrypted—based on the server key and command. The command can include instructions to gather more data from the user or about the computer before allowing access.

摘要： In general, this disclosure describes scalable, partitionable encryption engines. The partitionable encryption engines of this disclosure yield power savings, such as by controlling operation of partitioned sub-datapaths at reduced clock rates. An apparatus includes an interface configured to receive a block of encrypted data for decryption, and a decryption engine in communication with the interface. The decryption engine includes a plurality of decryption sub-datapaths, where each respective decryption sub-datapath has no data interdependency with any other decryption sub-datapath of the plurality of decryption sub-datapaths. The decryption engine is configured to selectively enable one or more decryption sub-datapaths of the plurality of decryption sub-datapaths to decrypt the block of encrypted data to form a decrypted block of data.

摘要： Using an association data structure corresponding to a derived decentralized identifier of a subject entity to share a verified claim about the subject entity to one or more relying entities. A decentralized identifier of a subject entity is derived from a source decentralized identity of the subject entity. Next, an association data structure is created using the derived decentralized identifier. The association data structure is structured to be interpretable by a relying entity as demonstrating that a verified claim is about the derived decentralized identity. The relying entity is then caused to be provided the verified claim about the subject entity. The verified claim includes the association data structure that was created using the derived decentralized identifier.
