Background
Digital asset trading, meaning that a customer has some solution X of the equation H (X) Y sold, where H is a programmable function, X is the solution to the function, and Y is the desired result. And when the B customer wishes to purchase the solution X, a digital asset transaction is generated.
For example, in a blockchain-based digital asset (token) trading system, when customer a issues a digital asset contract that does not specify a payee on the blockchain public/private/alliance chain.

Constract(As，Bs，X)＝Yb
the execution of the contract results in B customer obtaining digital asset X and A customer obtaining B customer's payment funds.
However, in the prior art, in order to avoid fraud when performing the above digital asset transaction, for example, a tells B to solve X and B does not pay, or a does not tell B to solve X after B pays, thus requiring the intervention of a third party, such as a transaction center or the like.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
Fig. 1 is a flowchart illustrating a digital asset receiving method according to the present invention, which includes:
step S101, responding to a transaction event, wherein the transaction event is that a digital asset sender sells a digital asset, and the digital asset obtains a preset expected result after inputting a preset programming function;
step S102, a first encryption operation value Xk and a second encryption operation value Hk are obtained, wherein Xk is a value obtained after a digital asset sender uses a random key K to perform first encryption operation on digital assets, and Hk is a value obtained after the random key is performed with second encryption operation;
step S103, initiating a payment operation to a payment system, wherein the payment operation pays funds to a digital asset sender when a value obtained after the second encryption operation is performed on an input value of the digital asset sender is consistent with Hk;
step S104, obtaining the input value of the digital asset sender from the payment system as a verification key;
and step S105, performing the inverse operation of the first encryption operation on Xk by using the verification key to obtain the digital asset.
Specifically, the present embodiment performs an encryption operation on the random key such that the digital asset receiver obtains a value encrypted by the random key, thereby hiding the random key, and therefore, all received by the digital asset receiver are encrypted values in step S101, and then performs verification of the payment operation using the second encryption operation value in step S103. Therefore, the unencrypted value of the digital asset is not available to the digital asset recipient until step S104, i.e., until the payment operation is complete. Then, after the verification password is obtained in step S104, the encrypted value of the digital asset may be decrypted to obtain the digital asset.
According to the invention, through the verification mode of the payment operation, both transaction parties can obtain the digital assets and funds at the same time, fraud is avoided, and the credible digital asset transaction is completed when no third party intervenes.
In one embodiment, the first encryption operation is a reversible encryption operation and the second encryption operation is an irreversible encryption operation.
Since the second encryption operation, that is, the encryption operation on the random key is an irreversible encryption operation, the encrypted value Hk of the random key cannot be decrypted through an inverse operation after being obtained by the digital asset receiver, thereby ensuring the security of the random key. After the payment operation is completed in step S104, the digital asset receiver obtains the random key, and performs the inverse operation of the first encryption operation by the random key to complete decryption, thereby obtaining the digital asset.
Specifically, the first encryption operation is preferably: advanced Encryption Standard (AES) that can be encrypted and decrypted by a key. The second encryption operation is preferably a hash obfuscation function, which is not invertible.
In one embodiment, after said responding to a transaction event, the method further comprises:
generating a judgment program, wherein input parameters of the judgment program comprise an input random key parameter and an input digital asset encryption parameter, the judgment program performs a second encryption operation on the random key parameter to obtain an output second encryption operation value parameter, inputs a value obtained by performing an inverse operation of a first encryption operation on the input digital asset encryption parameter by the input random key parameter into the programming function to obtain an output expected result parameter, and returns the input digital asset encryption parameter, the output second encryption operation value parameter and the output expected result parameter;
uploading the judgment program to a black box operation server, receiving an input digital asset encryption parameter, an output second encryption operation value parameter and an output expected result parameter returned by the black box operation server;
and if the output expected result parameter is consistent with the expected result, taking the input digital asset encryption parameter as a first encryption operation value Xk and taking the second encryption operation value parameter as a second encryption operation value Hk.
The present embodiment adds a decision-making procedure to enable both parties to the transaction to confirm the authenticity of the digital asset. Since the digital asset is a solution X of the equation H (X) ═ Y, the present embodiment performs determination by a determination program in order to determine that the solution X can be calculated by the function H to obtain Y before trading. After the digital asset sender confirms that the digital asset cannot be leaked, the judgment program provided by the digital asset receiver is uploaded to a black box operation server, such as a sandbox space, and the black box operation server only has input and output interfaces, so that the random key provided by the digital asset sender can be ensured not to be directly acquired by the digital asset receiver. After the judgment program judges that the expected result parameters are output, the digital asset receiver can be considered to provide a correct key when confirming that the expected result parameters are output to be consistent with the expected result, but the digital asset receiver cannot directly obtain the random key because the judgment program outputs only the encrypted value of the random key. After payment operation is carried out, the unencrypted random key can be obtained, so that not only the authenticity of the digital asset is ensured, but also the safety of the digital asset is ensured.
Fig. 2 is a flowchart illustrating a method for sending a digital asset according to the present invention, which includes:
step S201, initiating a transaction event, wherein the transaction event is a sale digital asset, and a preset expected result is obtained after the digital asset is input into a preset programming function;
step S202, a random key K is used for carrying out first encryption operation on digital assets to obtain a first encryption operation value Xk, the random key K is used for carrying out second encryption operation to obtain a second encryption operation value Hk, and the first encryption operation value Xk and the second encryption operation value Hk are obtained by a digital asset receiving party;
step S203, responding to a verification request of a payment operation initiated by the digital asset receiving party to a payment system, inputting the random key K to the payment system, paying funds when a value obtained after the random key K is subjected to the second encryption operation is consistent with Hk, sending the random key K to the digital asset receiving party by the payment system, and performing reverse operation of the first encryption operation on Xk by the digital asset receiving party to obtain the digital asset by the verification key K.
The digital asset sending method of the digital asset sender in this embodiment initiates a transaction through step S201, for example, a digital asset contract that does not specify a payee is issued on the blockchain public/private/alliance chain. Then, in step S202, the digital asset is encrypted by the random key K, and in step S203, the random key K is input to the payment system to verify the payment operation initiated by the digital asset recipient and finally obtain the payment funds.
In one embodiment, after obtaining the first encryption operation value Xk after the first encryption operation is performed on the digital asset by using the random key K, the method further includes:
inputting the random key K, the first encryption operation value Xk and the programming function into a judgment program uploaded to a black box operation server by a digital asset receiving party, wherein input parameters of the judgment program comprise an input random key parameter and an input digital asset encryption parameter, the judgment program performs second encryption operation on the random key parameter to obtain an output second encryption operation value parameter, inputs a value obtained by performing inverse operation of the first encryption operation on the input digital asset encryption parameter by the input random key parameter into the programming function to obtain an output expected result parameter, and returns the input digital asset encryption parameter, the output second encryption operation value parameter and the output expected result parameter;
when the judgment program is input, the random key K corresponds to an input random key parameter, the first encryption operation value Xk corresponds to an input digital asset encryption parameter, the programming function corresponds to the input programming function parameter, the returned input digital asset encryption parameter, an output second encryption operation value parameter and an output expected result parameter are obtained, when the digital asset receiving party receives the output expected result parameter from the judgment program and is consistent with the expected result, the input digital asset encryption parameter is used as the first encryption operation value Xk, and the second encryption operation value parameter is used as the second encryption operation value Hk.
As shown in fig. 3, as a preferred embodiment of the present invention, for equation H (X) Y, where H is a programmable function, X is the solution of the function, and Y is the desired result. When a client a has a solution X of the equation to sell and B client B wishes to purchase the solution X, a digital asset trading method of a preferred embodiment of the present invention, without the intervention of a third party or the presence of a third party to which both parties are trusted, comprises:
in step S301, the client a initiates a transaction event as a sender of the digital asset, and encrypts the digital asset X by using a random number K to form Xk, i.e., Xk ═ AES (X, K).
In step S302, the client B, as a digital asset receiver, constructs an executable decision program in response to the transaction event, as follows:
Program(K，Xk，H())＝>[Xk，Hk，Y]{
hk — SHA512 (K); // SHA512 is a hash obfuscation function, i.e., hash obfuscating K, which is not invertible, so that anyone knows that Hk cannot deduce K back.
And Y is H (UN-AES (Xk, K))// the target function operation is executed after Xk is decrypted, and the expected result Y is calculated, wherein the UN-AES is the inverse operation of the AES.
return[Xk，Hk，Y]
}
Step S303, after the client A confirms that the judgment program is correct, namely X is not leaked, the client B uploads the judgment program to a cloud sandbox space, the sandbox space is a black box operation server, and only input and output are allowed to be acquired by a user.
In step S304, the client a transmits K, Xk as an input to the Program, and outputs answers Xk, Hk, and Y to the client B.
Step S305, the client B initiates a payment operation to the client a through a payment system, such as a payment interface of a bank, using the obtained Hk, where the payment operation is verified in the following manner:
SHA512(K)＝Hk。
in step S306, the client a inputs K so as to satisfy the equation Hk — SHA512(K), and after the authentication is passed, K is transmitted to the B client, and the payment operation completes the payment of funds to the account of the client a.
Step S307, after obtaining K, the client B obtains X by decrypting Xk, that is: x is UN-AES (Xk, K).
The transaction mode of the embodiment enables the buyer and the seller to carry out safe transaction, and the transaction parties cannot carry out fraud, so that trust is not needed.
