Abstract

The invention provides a blockchain account processing method and apparatus, and a storage medium. The blockchain account processing method comprises the steps of obtaining a request for generating ablockchain account; generating a random polynomial, and generating a quantum private key according to the random polynomial and the request; generating a quantum public key from the quantum private key through a Falcon encryption algorithm; and performing Hash mapping and coding on the quantum public key to obtain a quantum wallet address corresponding to the quantum public key. The quantum publickey is generated through the Falcon encryption algorithm, the security level of the block chain account is improved, and cracking of an existing block chain account system by a quantum computer can be resisted; Compared with an existing secret key formed by a student with a later quantum password, the quantum private key and the quantum public key generated by the method are smaller in storage space and faster in signature and verification speed, and the operation burden caused to the block chain server is also reduced.

Description

technical field

[0001] The present invention relates to the field of computer technology, in particular, the present invention relates to a processing method, device and storage medium of a blockchain account. Background technique

[0002] With the improvement of computer computing power, the password length of public key cryptography has been increasing in order to ensure security. After the length of the key increases, the existing public key cryptography needs to perform exponential operations in a larger finite field, which makes the existing public key cryptography more prominent in terms of the efficiency of key generation and decryption. Elliptic curve cryptosystems is an encryption algorithm with higher complexity but shorter key length. The current blockchain account system mainly uses the parameters of the secp256k1 curve based on the discrete logarithm of the elliptic curve, such as Bitcoin and Ethereum. Secp256k1 is a parameter of the Elliptic Curve Digital Sig...
