Multiple systems may determine neural-network output data and neural-network parameter data and may transmit the data therebetween to train and run the neural-network model to predict an event given input data. A data-provider system may perform a dot-product operation using encrypted data, and a secure-processing component may decrypt and process that data using an activation function to predict an event. Multiple secure-processing components may be used to perform a multiplication operation using homomorphic encrypted data.

A method (300) and system (1) of determining a common secret for two nodes (3, 7). Each node (3, 7) has a respective asymmetric cryptography pair, each pair including a master private key and a master public key. Respective second private and public keys may be determined based on the master private key, master public key and a deterministic key. A common secret may be determined at each of the nodes based on the second private and public keys. In one example, a node (3, 7) may determine the common secret based on (i) a second private key based on the node's own master private key and the deterministic key; and (ii) a second public key based on the other node's master public key and the deterministic key. The invention may be suited for use with, but not limited to, digital wallets, blockchain (e.g. Bitcoin) technologies and personal device security.

A processor with an elliptic curve cryptographic algorithm and a data processing method thereof are shown. The processor has a first register storing a Hash value pointer, a second register storing a public key pointer, a third register storing a signature pointer, and a fourth register for storage of a verified result. In response to a first elliptic curve cryptographic instruction of an instruction set architecture, the processor reads the Hash value of the data by referring to the first register, obtains the public key by referring to the second register, obtains the digital signature to be verified by referring to the third register, performs a signature verification procedure using the elliptic curve cryptographic algorithm on the Hash value based on the public key and the digital signature to be verified to generate the verified result, and programs the verified result into the fourth register.

Post quantum secure network communication is provided. The process comprises sending, by a client in a first computing cluster, an outbound message to a quantum safe cryptographic (QSC) proxy server in the first computing cluster, wherein the outbound message is addressed to a target server in a second computing cluster. The QSC proxy server initiates a QSC transport layer security (TLS) connection with an ingress controller in the second computing cluster, wherein the ingress controller comprises a QSC algorithm. The QSC proxy server transfers the message to the ingress controller via the QSC TLS connection, and the ingress controller routes the message to the target server in the second computing cluster via a non-QSC connection.
