Fig. 1 is a schematic diagram of a method for creating a blockchain account according to an embodiment of the present application, where the method includes:

and S101, extracting the algorithm related to the account, packaging into an algorithm group and numbering.

And extracting algorithms related to the account on the block chain, and packaging the algorithms into an algorithm combination, wherein the algorithm combination comprises an asymmetric encryption algorithm related to the secret key, a public key calculation algorithm, an account address assembling algorithm and a hash algorithm used in signature and signature verification. And numbering the algorithm combinations, wherein the numbering corresponds to the algorithm combinations one by one. The user does not manipulate the code and algorithm, but selects the combination of algorithms actually used by selecting the number of the combination of algorithms.

Preferably, the blockchain can preferentially support the common algorithms which are relatively safer and more efficient, and the related algorithms are completely unnecessary to be written from scratch by itself.

Preferably, a user can be provided with a plurality of common, safe and efficient algorithm combinations, so that the learning and understanding of algorithm-related knowledge of the user are reduced.

Optionally, some countries or regions have mandatory requirements for asymmetric encryption algorithms and hash algorithms, and it is recommended to select an algorithm meeting the requirements.

S102, the user selects an algorithm combination.

The blockchain provides the user with a list of numbers of combinations of algorithms supported by the blockchain, from which the user selects a number. The user selects the number, which indicates that the user selects to use the algorithm combination corresponding to the number.

Optionally, the user can check the advantages and disadvantages of various algorithm combinations, and corresponding prompts can be provided in time when the user selects the algorithm combination, so that the user is helped to select a proper algorithm combination.

S103, generating a secret key and calculating the public key.

And generating a secret key by using an asymmetric encryption algorithm in the algorithm combination according to the algorithm combination selected by the user, and then calculating the public key.

Preferably, only a variable portion of the public key is calculated for public key calculation, since the asymmetric encryption algorithm is explicitly specified in the selected combination of algorithms.

Alternatively, the variable part of the public key can be directly converted into a byte array to be spliced.

Optionally, if the asymmetric encryption algorithm specified in the algorithm combination is an elliptic curve encryption algorithm, the coordinates of the public key of the secret key are directly converted into two byte arrays to be spliced.

Further, considering that the concatenated byte array is too long, a hash algorithm may be used to change the byte array to a shorter one. Optionally, the serial number of the algorithm combination may be spliced to the byte array and then hashed by using a hash algorithm, so that the validity of the account address can be verified subsequently. Further, a sufficiently long section may be cut from the hash result as a calculation result. Optionally, 19 bytes are intercepted from the hash result, at this time, 19 different samples to be hashed representing 256 times must collide, but 19 times of 256 is a large number, and it should be considered that the probability of collision is low, that is, the intercepted result can replace the hash result, and at this time, the intercepted result is taken as the calculation result.

Further, optionally, a simple check code may be added after the splicing result, and algorithms of different check codes are often different. Common check code algorithms are: code distance, parity check, hamming check, cyclic redundancy check, etc.

Optionally, the calculation result of the public key and the number are assembled according to a certain coding format, and the coding technology may be an abstract language notation (ans.1), a recursive length prefix coding (RLP), or the like.

Therefore, the account is associated with the algorithm combination, the account does not depend on a specific block chain any more, the account signature and the algorithm combination associated with the account are used during signature verification, the algorithm combination used by the account can be known through the account address, one block chain can support various algorithm combinations, and the account addresses of different algorithm combinations are different.

Fig. 2 is a schematic structural diagram of an apparatus for creating a blockchain account according to an embodiment of the present disclosure. The device comprises:

an algorithm configuration module:

a list of numbers of algorithm combinations currently supported by the blockchain is provided, indicating that the blockchain already supports the corresponding algorithm combination, and accounts created on any blockchain using any one of the algorithm combinations in the list can be used on that blockchain. Accounts created by combinations of algorithms other than the numbered list are temporarily unsupported. Since the account address contains the number of the algorithm combination used by the account, whether the account corresponding to the account address can be used on the block chain can be directly judged through the account address.

The management of the numbering is important since the numbering of the algorithm combinations directly determines which algorithm combination to use for the account. All blockchains must use a uniform number to manage the algorithm combinations, only to ensure that the number in the account address is valid across all blockchains. Considering that the algorithm combinations belong to a bottom-layer architecture and generally do not relate to specific services, and the asymmetric encryption algorithm and the Hash algorithm in the algorithm combinations are limited in types and open in code sources, a neutral platform can be provided for uniformly managing numbers, so that different algorithm combinations can be conveniently supported, and the research and development cost of an account system can be reduced.

Preferably, related algorithms or codes involved in the algorithm combination can be directly disclosed, so that the transparency of an account system can be increased, and the concern of enterprises and users in using the algorithm combination is reduced.

Preferably, popular, open source and free algorithms should be supported in preference to asymmetric encryption algorithms and hash algorithms due to their high development and verification costs.

Preferably, different asymmetric encryption algorithms and hash algorithms have different efficiencies, and part of the hash algorithms have security risks, so that the asymmetric encryption algorithms with high efficiency, existing market popularity and high security can be selected to be combined with the hash algorithms, and then related algorithms are considered to be re-developed.

When the block chain does not support a certain algorithm combination, the algorithm configuration module can inform the user and the block chain in time, and can dynamically load the codes of the algorithm combination to support the algorithm combination, so that more accounts can be quickly supported.

A creation module:

finding out a corresponding algorithm combination according to the input number, then creating a key by using an agreed asymmetric encryption algorithm in the algorithm combination, calculating a public key of the key, and assembling a calculation result and the number of the algorithm combination into an account address. Optionally, because different asymmetric encryption algorithms have different requirements on the seeds, if a user creates a key by specifying the seed of the key, the seed needs to be verified according to the requirements of the asymmetric encryption algorithms in the algorithm combination, the seed that does not meet the requirements is rejected, and the seed that meets the requirements is accepted.

A signature module:

and hashing the data to be signed by using the hash algorithm of the algorithm combination, and then signing the hashed result by using a private key of the secret key.

A label checking module:

directly resolving the account address of the data to be checked to obtain the number of the algorithm combination, then obtaining the algorithm combination corresponding to the number, hashing the data part to be checked by using the hash algorithm in the algorithm combination, and finally checking the signature by using the account address, the hash result and the signature part to be checked.
