摘要： An electronic device, in disclosed embodiments, includes an antenna, transceiver circuitry coupled to the antenna, a memory configured to store a first operation key and instructions, and a processor coupled to the transceiver and to the memory. The processor is configured to execute the instructions stored in the memory to cause the electronic device to, in response to receiving a first transmission containing an encrypted version of a second operation key that is encrypted by the first operation key, decrypt the encrypted version of the second operation key using the first operation key to recover the second operation key, store the second operation key in the memory, transmitting, by a transmitter of the electronic device, a second transmission that contains the first operation key and a command.

摘要： Methods and systems for secure computation and communication are provided. The method includes transforming identifications of a first dataset using a first transforming scheme, and transforming attributes of the first dataset using a second transforming scheme. The method also includes dispatching the transformed first dataset, receiving a second dataset, transforming identifications of the received second dataset, dispatching the identifications of the transformed received second dataset, and receiving a set of identifications. The method further includes generating a first intersection of the received set of identifications and the transformed received second dataset, generating a first share based on the first intersection, receiving a second share, and constructing a result based on the first share and the second share.

摘要： A method of sharing a first common secret among a plurality of nodes (A, B, C) for enabling secure communication for blockchain transactions comprises: determining, a first node (A) a plurality of second common secrets (SAPC, SAPB), wherein each second common secret is common to first node and a second node (B), determined at first node based on a first private key of first node and a first public key of second node (PC, PB) determined at the second node based on the first private key of the second node (SB, SC) and the first public key of the first node (PA). A third common secret (SBPC, SCPB) common to the second node (B) and a third node (C) is determined for the second node. The method comprises encrypting, at the first node, shares of first common secret known to the first node, and sending encrypted shares to second nodes.

摘要： A method includes performing a cryptographic operation using a processing device. The performing the cryptographic operation includes protecting the performing of the cryptographic operation against side channel attacks by selecting a value amongst two values based on a selection bit. Selecting the value includes concatenating the two values in a register, generating a concatenated word including the two values in two distinct portions of the concatenated word in the register. The concatenated word is rotated according to the value of the selection bit to position the selected value in a determined portion of the concatenated word in the register amongst said two portions. The unselected value in the concatenated word is suppressed. One or more processing operations is performed based on a result of the cryptographic operation.

摘要： Techniques are provided to implement the functionality of a logic gate by blockchain transaction. A method includes providing a locking script in a first transaction, comprising an instruction to process Boolean input; providing a further transaction having an unlocking script; processing an input signal to provide a Boolean input; and using the Boolean input to execute the locking and unlocking scripts of the first and further transactions, wherein the computing resource or agent influence the behaviour of a device or process based upon the validity of the further transaction; transmitting the further transaction and/or first transaction to a blockchain network for validation; interpreting the detecting of the further transaction within the blockchain or blockchain network as the TRUE output of a logic gate; and interpreting the failure to detect the further transaction within the blockchain or blockchain network as the FALSE output of the logic gate.

摘要： A method of sharing a first common secret among a plurality of nodes for enabling secure communication for blockchain transactions. The method comprises determining, for at least one first node a plurality of second common secrets, wherein each second common secret is common to the first node and a respective second node, is determined at the first node based on a first private key of the first node and a first public key of the second node and is determined at the second node based on the first private key of the second node and the first public key of the first node. The method further comprises exchanging encrypted shares of the first common secret among the plurality of nodes to enable each of the plurality of nodes to reach a threshold number of shares of the first common secret to access the first common secret.
