A method for protecting the private key of encrypted currency

Abstract

The invention provides a method for protecting a private key of encrypted currency, comprising the following steps: S1 preprocessing the private key K of encrypted currency to obtain a key data stream M; S2 determining the number n of storage media, secretly selecting a prime number p and t number a j , openly choose n different numbers x i , get n key units y through function calculation i , the n key units y i respectively distributed to n different storage media, and the key unit y i The corresponding storage medium is marked with serial number i; S3 obtains any t+1 storage medium, and reads the key unit y in each storage medium i , and determine the corresponding x according to the serial number i marked on the storage medium i , construct a system of equations according to the function, and solve the system of equations to obtain the key data stream M; S4 restores the key data stream M to obtain the encrypted currency private key K. The beneficial effects of the present invention are as follows: the security of storing the private key of the encrypted currency is improved, the risk caused by the loss of the private key is reduced, and the rights of the holder of the encrypted currency are protected.

Description

technical field [0001] The invention relates to the technical field of cryptographic currency security protection, in particular to a method for protecting a cryptographic currency private key. Background technique [0002] Cryptocurrency is the core technology in the current Internet financial field. The core element of the circulation of digital cryptocurrency such as Bitcoin, Ethereum, Hyperledger and IOTA currency is the user's password private key. Owning the user's private key means that you can obtain the use of the cryptocurrency At present, the common cryptocurrencies usually verify the transaction through the private key. The loss of the private key will directly cause the loss of the cryptocurrencies and affect the deflation. If the key is lost, the encrypted currency is lost and cannot be retrieved. How to use the secret sharing mechanism to design a private key storage method to effectively protect the user's private key is a technical problem that needs to be ...

[0002] Cryptocurrency is the core technology in the current Internet financial field. The core element of digital cryptocurrency circulation such as Bitcoin, Ethereum, Hyperledger and IOTA coin is the user's password private key. Owning the user's private key means that you can obtain the use of the cryptocurrency At present, common cryptocurrencies generally verify transactions through private keys. The loss of private keys directly causes the loss of cryptocurrencies and affects deflation. At present, there is still a lack of effective private key protection methods and emergency protection methods for loss. If the key is lost, the password is lost and cannot be retrieved
