Problems solved by technology

So generally speaking, this method is only used for a small amount of data encryption;
[0014] 2. In RSA encryption technology, when the public key is known, the number encapsulated into the private key may be deduced, which means that the private key may be cracked, which is very insecure

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0038] Terminology Explanation: Blockchain is a series of data blocks associated with each other using cryptographic methods. Each data block contains the information of a network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. .

[0039] In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in...

Abstract

The embodiment of the invention discloses a method and apparatus for generating private keys in batches based on block chains, and belongs to the field of block chains. The method for generating the private keys in batches based on the block chains comprises the following steps: step S100, selecting a block in a current time block chain; step S101, extracting a hash value H(k) and transaction information data Dkn from the block; step S102, splicing the hash value H(k) and the transaction information data Dkn in the block, and performing hash calculation to generate a random number; and step S103, generating private keys based on the random number and identity information. According to the method disclosed by the embodiment of the invention, all blocks in the current block chain can be selected at the same time, the hash values and the transaction information data in the blocks are spliced to generate the random numbers, and a large number of private keys are quickly generated based on the random numbers and the identity information.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and device for generating a large number of private keys based on block chains. Background technique [0002] The digital currency is called DIGICCY for short, which is the abbreviation of "Digital Currency" in English. Digital currency is an alternative currency in the form of electronic currency, and both digital gold coins and encrypted currencies are digital currencies. Digital currency cannot be completely equated with virtual currency in the virtual world, because it is often used for real goods and service transactions, not just limited to virtual spaces such as online games. [0003] As digital currencies receive more and more attention, the corresponding digital wallets are becoming more and more important. The most important thing for users is the private key of the digital wallet. With the private key, users can trade their own digital assets; if the pr...
