摘要： An information security protection method includes: repeatedly substituting a plaintext into an encryption algorithm to obtain a plurality of ciphertexts, and determining whether the ciphertexts are all the same h the processor core. Each time the processor core substitutes the plaintext into the encryption algorithm, the encryption algorithm outputs a ciphertext. When the processor core determines that the ciphertexts are not all the same, the processor core outputs a hacker attack message, which means that an encryption process has suffered a hacker attack.

摘要： Software installed in the nodes in a communication network allows them to perform a “name server” function, which entails the management of a dynamic list of the client devices that are connected to the cloud, a “task” function, which entails the receipt and transmission of the packets, and an “authority” function, which entails the determination of the routes of the packets through the cloud. Each node is capable of performing only one function at a time. After completing a job, a node reverts to an undifferentiated, state awaiting its next performance request.

摘要： Techniques for obfuscating and/or de-obfuscating data using bit-level shard masks are disclosed. Shard masks are generated. The shard masks are designed to shard a block of data into a number of shards for distribution and storage among a number of storage arrays. The shard masks shard the block of data at a bit-level granularity. The shard masks are applied to the block of data to generate the shards. The shards are then distributed among the storage arrays for storage on the storage arrays.

摘要： A system and method for block management of interactions comprising a network-connected block management computer connected to a plurality of connected devices and to one or more blockchains to enable an object compiler to receive a plurality of criteria from a requesting device. The compiler the receives a plurality of blocks from the blockchains based on the criteria. Each block corresponding to a preconfigured interaction object previously written by devices either during or after the completion of a transaction. The compiler analyzes the preconfigured interaction objects to determine if there is corresponding supplemental object. The compiler requests the supplemental blocks from the blockchains, and processes supplemental objects based on type, if no corresponding supplemental object it found, the associated interaction object is flagged.

摘要： A method, computer system, and a computer program product for blockchain enabled crowdsourcing is provided. The present invention may include receiving an asset from a content provider. The present invention may also include deploying a smart contract based on the received asset, wherein the deployed smart contract includes a plurality of compensation rules. The present invention then may include partitioning the received asset into a plurality of fragments based on the deployed smart contract. The present invention may further include releasing the partitioned plurality of fragments into a blockchain network. The present invention may also include tracking each fragment within the released plurality of fragments using the smart contract.

摘要： Methods, apparatus, systems, and articles of manufacture are disclosed. An example apparatus includes: interface circuitry to receive a first value and a second value; selector circuitry to select a first subset of bits and a second subset of bits from the first value; multiplier circuitry to: multiply the first subset to the second value during a first compute cycle; and multiply the second subset to the second value during a second compute cycle; left shift circuitry to perform a bitwise shift with a product of the first subset and the second value during the second compute cycle; adder circuitry to add a product of the second subset and the second value to a result of the plurality of bitwise shift operations during the second compute cycle; and comparator circuitry to determine the result of the modular multiplication based on a result of the addition during the second compute cycle.

摘要： A user station for a serial bus system. The user station includes a communication control device for controlling a communication of the user station with at least one other user station, and a transceiver device to serially transmit a transmission signal generated by the communication control device onto a bus and to serially receive signals from the bus. The communication control device generates the transmission signal according to a frame, and inserts a header check sum into the frame, only bits of a frame header that is situated in front of a data field provided for useful data in the frame being included in the computation. For computing the header check sum, the communication control device uses a predetermined starting value and a predetermined check sum polynomial.

摘要： A method, apparatus, and system for assigning the execution of a cryptography and/or compression operation on a data segment to either a central processing unit (CPU) or a hardware cryptography/compression accelerator is disclosed. In particular, a data segment on which a cryptography and/or compression operation is to be executed is received. Status information relating to a CPU and a hardware cryptography/compression accelerator is determined. Whether the operation is to be executed on the CPU or on the hardware accelerator is determined based at least in part on the status information. In response to determining that the operation is to be executed on the CPU, the data segment is forwarded to the CPU for execution of the operation. On the other hand, in response to determining that the operation is to be executed on the hardware accelerator, the data segment is forwarded to the hardware accelerator for execution of the operation.
