Abstract

The invention provides an IDA-based digital wallet initialization method and apparatus. The method comprises the steps of performing calculation according to a real electronic bank account of a user to generate an SM3 digital abstract; dividing 256 digits of the SM3 digital digest into two groups and carrying out exclusive-OR operation; dividing the result of the XOR operation into 26 groups; converting the binary value of each of the 26 groups into a decimal number; searching character representations corresponding to the decimal numerical values in a coding dictionary respectively, and splicing the character representations into a character string in sequence, the character string being the digital wallet ID; applying a secret key to a secret key center, the secret key center calculatesand generates a private key corresponding to the digital wallet ID, and the private key is returned and stored in a secret key security device of the digital wallet; and applying for account opening of the digital wallet ID from a commercial bank, and signing the digital wallet ID with a private key of the commercial bank. According to the scheme of the invention, the security of the encrypted digital currency in the digital wallet is ensured.

Description

technical field [0001] The invention relates to the technical field of computer and information security, in particular to an IDA-based digital wallet initialization and usage method and system. Background technique [0002] Since 2014, the People's Bank of China has been researching digital currency for 5 years. In August 2019, the People's Bank of China officially clarified the policy on digital currency: First, China's digital currency is issued by the central bank and operated by commercial banks. Rather than the replacement of M1 and M2; the third is that there are no restrictions on the technical route of digital currency, and commercial banks can choose their own suitable technology, allowing to optimize the technical route through market competition. [0003] In order to ensure the security of digital currency, encrypted digital currency based on cryptographic technology is needed. At present, there is a mature cryptographic technology PKI CA system in the existing ...
