[0018] Glossary

[0019] Blockchain - A ledger of all transactions conforming to one or more standards or conventions associated with a blockchain. One or more computing devices may include a blockchain network that may be configured to process and record transactions as part of blocks in the blockchain. Once a block is finalized, the block is added to the blockchain, thereby updating the transaction record. In many cases, a blockchain can be a ledger of transactions in chronological order, or can be presented in any other order suitable for use by a blockchain network. In some configurations, the blockchain may be a ledger of monetary transactions, where transactions recorded in the blockchain may include destination addresses and amounts of currency, such that the blockchain records how much currency is attributed to a particular address. In some such configurations, the blockchain may use a blockchain-based digital currency, which may be unique to the respective blockch...

Abstract

A method for distributing a plurality of cryptographic keys for accessing data comprising: receiving a data signal superimposed with a request for an access key, wherein the request for an access key includes at least a number n of requested keys greater than one; Generating n key pairs using a key pair generation algorithm, where each key pair includes a private key and a public key; deriving the key by applying the private key contained in each of said n key pairs to algorithm to derive a private access key; use a key pair generation algorithm to generate a public access key corresponding to the derived private access key; and for each of the n key pairs, electronically transmit a superimposed A data signal for the private key in one of the key pairs.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from the filing date of US Patent Application Serial No. 15 / 001,775, filed January 20, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] This disclosure relates to the distribution of multiple cryptographic keys used to access data, and in particular, the use of elliptic curve cryptography to securely distribute multiple cryptographic keys that are used to derive a single key for cryptographic Access to data by key recipients requires negotiating ownership of the data. Background technique [0004] In a world of billions of computing devices, data is constantly being transferred. Data may be transferred from one computing device to another, from one computing device to many other computing devices, or from many computing devices to a single computing device. In many cases, the security of data transmission may be as important...
