Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.
It should be noted that technical terms or scientific terms used in the embodiments of the present application should have a general meaning as understood by those having ordinary skill in the art to which the present application belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
As described in the background section, in the currently common asset transfer, only the private key of the asset transfer initiator is needed to sign the transaction initiating the transfer, and the signed transaction is sent to the block chain. Once the private key of the asset transfer initiator is leaked, the private key thief can initiate a transfer transaction to any person, so that the rights and interests of the asset transfer initiator are damaged.
However, the inventor finds that in the related art, the scheme for dealing with the private key disclosure basically needs to disassemble the transfer flow, and the assets are transferred to a trusted third party and then are extracted from the trusted third party after the recipient is authenticated by the authority. Although the security is ensured, the original one transaction (also called transaction, which refers to an interaction that changes the state of the blockchain once) is split into two transactions, that is, the number of times of blockchain transactions is increased, which also brings inconvenience to the system conforming to the original flow.
Therefore, according to the information transfer method, the information transfer device and the related equipment provided by the application, after the sending end receives the transfer frequency information signed by the receiving end, the sending end sends the information transfer request and the transfer frequency information to the intelligent contract end, whether the signature of the transfer frequency information is the same as that of the receiving end is determined through the intelligent contract end, when the signature of the transfer frequency information is determined to be the same as that of the receiving end, mutual trust between the sending end and the receiving end is proved, and the target information can be sent to the receiving end through the intelligent contract end. This application guarantees not to introduce the third party through the block chain technique to make the information transfer only go on between sending end and receiving terminal, intelligent contract end then is used for verifying whether can carry out the information transfer between sending end and the receiving terminal, reduces the information transfer number of times, guarantees that target information shifts between as few as possible terminal, has guaranteed user information's security. Moreover, the signed transfer frequency information is used as the verification information, and the transfer frequency is updated after information transfer is completed every time, so that the signed transfer frequency information generated in every information transfer is different, and even if a private key of a sending end is stolen, an eavesdropper cannot forge the verification information through the previously disclosed transfer frequency information and signature, and then the information of the stolen end is transferred out, and the safety of user information is further ensured.
The following describes the information transfer method provided in the embodiments of the present application with specific examples.

Fig. 3 illustrates an exemplary flowchart of an information transfer method applied to an intelligent contract end according to an embodiment of the present application.
S302: and responding to the received information acquisition request sent by the receiving end, and sending the transfer times between the receiving end and the sending end to the receiving end.
S304: responding to the received information transfer request and the transfer frequency information sent by the sending end, and determining whether the signature of the transfer frequency information is the same as that of the receiving end; wherein the transfer time information is determined according to the transfer times.
S306: and responding to the fact that the signature of the transfer time information is the same as the signature of the receiving end, receiving the target information sent by the sending end, sending the target information to the receiving end, and updating the transfer time information.
In some embodiments, before the sender wants to perform information transfer with the receiver, for example, before the sender wants to transfer digital assets to the receiver, the sender may notify the receiver that information transfer is to be performed, and specifically, the sender may send transfer notification information to the receiver, where the transfer notification information may include sender identity information.
Further, the receiving end may determine the identity of the sending end according to the transfer notification information, for example, may determine that the sending end is Alice. The sending end can not only carry out information transfer with the receiving end by itself, but also can carry out information transfer with the receiving end for the agent end Lily on the premise of having authority, and the agent end can authorize the sending end to carry out information transfer for the agent end Lily. Therefore, the receiving end can determine which terminal the information transfer is with. Taking the example that the sending end Alice and the receiving end perform information transfer, the intelligent contract end can be accessed to read the transfer times between the receiving end and the sending end, that is, the times of information transfer between the receiving end and the sending end, by sending an information acquisition request to the intelligent contract end. In order to indicate the identity of the receiving end and ensure the safety in the information transfer process, the receiving end can use the own account private key to sign the transfer times, so as to determine the transfer time information.
It should be noted that the transfer number information is determined after the transfer number and the private key of the receiving end are signed, that is, the transfer number and/or the private key of the receiving end change, and the transfer number information also changes.
And then, the receiving end can send the signed transfer number information to the sending end, and at the moment, the sending end can encrypt the information transfer request and the transfer number information signed by the receiving end by using an account private key of the sending end to generate a data packet encrypted by the sending end and send the data packet to the intelligent contract end so as to verify the identity legitimacy of the sending end and the receiving end through the intelligent contract end.
In some embodiments, when the intelligent contractual end receives the information transfer request and the transfer number information sent by the sending end, the intelligent contractual end may verify a signature of the transfer number information to determine whether the information transfer between the sending end and the receiving end can be performed.
Specifically, the intelligent contract end can read the transfer times of information stored between the sending end and the receiving end in the intelligent contract, and then can publish the transfer times and related information to each node in the block chain, and calculate the transfer time information by using each node, and then determine whether the signature of the transfer time information sent by the sending end is the same as the signature of the receiving end.
It should be noted that, transfer frequency information, signatures and other fixed information before information transfer is disclosed on the blockchain, and in the related art, when a sending end is attacked by a thief and a private key of the sending end is revealed, the thief may transfer the information of the sending end, thereby causing the disclosure of user information. That is, if the intelligent contract end verifies whether the signature of any one piece of fixed information is the same as the signature of the receiving end, the thief can generate a signature which is the same as the signature of the receiving end by acquiring the fixed information of the receiving end which is disclosed in the past and the signature, and the fixed information does not change, so that the signature of the fixed information cannot be changed, and the signature can be easily acquired by the thief, and further the leakage and loss of user information are caused.
In the application, the receiving end signs the transfer times to determine the transfer time information, and when the receiving end and the sending end perform information transfer once in the past, the transfer times between the sending end and the receiving end recorded in the intelligent contract end is increased by 1, so that the transfer time information changes along with the information transfer between the receiving end and the sending end, that is, a thief can obtain the previous transfer time information, but the transfer times change every time, so the transfer time information is different. And once the intelligent contract end detects that the transfer time information sent by the sending end is different from the calculated transfer time information, determining that the signature of the transfer time information sent by the sending end is different from the signature of the receiving end.
Furthermore, the intelligent contract end can send a transfer termination instruction to the sending end to indicate the sending end to exit the intelligent contract end, and the information transfer operation is not continuously executed, so that the information security of the user is guaranteed.
Still further, if the intelligent contract end determines that the transfer time information sent by the sending end is the same as the calculated transfer time information, the signature of the transfer time information sent by the sending end is the same as the signature of the receiving end, and the sending end can generate target information and send the target information to the receiving end through the intelligent contract end so as to complete information transfer.
In some embodiments, since the agent end of the sending end agent actually performs information transfer with the receiving end, when the sending end receives authorization information of the agent end, target information may be generated according to the agent end, for example, the transferred information is a digital asset, and when the sending end performs information transfer for the agent end, the target information is a digital asset of the agent end. When the signature of the transfer frequency information is determined to be the same as that of the receiving end, the sending end can operate the agent end to send the target information to the receiving end through the intelligent contract end so as to complete information transfer.
In some embodiments, in order to ensure a trust relationship between the sending end and the receiving end, the sending end may be provided with a white list, and the intelligent contract end may determine whether the signature of the transfer time information is in the transfer white list of the sending end, and once the signature is in the transfer white list, determine that the signature of the transfer time information is the same as the signature of the receiving end, and may complete information transfer between the sending end and the receiving end.
In some embodiments, to further ensure information security of the user, the intelligent contract end may determine whether the number of times of transfer between the sending end or the agent end and the receiving end is 0, and when the number of times of transfer between the sending end or the agent end and the receiving end is not 0, prove that the information transfer between the sending end or the agent end and the receiving end is performed for a plurality of times, and if the trust degree between the sending end and the receiving end is higher, once it is determined that the signature of the transfer number information is the same as the signature of the receiving end, the information transfer between the sending end or the agent end and the receiving end may be completed. And if the transfer times between the intelligent contract end and the sending end are 0, the fact that information transfer between the intelligent contract end and the sending end is not carried out is proved, the trust degree between the intelligent contract end and the sending end is difficult to determine, and once any one end in the current information transfer is suspected to be stolen, the intelligent contract end can send a transfer termination instruction to the sending end to indicate the sending end to terminate the information transfer operation and quit the intelligent contract end. And if the user thinks that every end in the current information transfer is not stolen, even if the transfer times between the sending end or the agent end and the receiving end is 0, the information transfer between the sending end or the agent end and the receiving end can be further completed under the condition that the signature of the transfer time information is determined to be the same as the signature of the receiving end.
As can be seen from the above, according to the information transfer method, apparatus, and related device provided by the present application, after receiving the transfer time information signed by the receiving end, the sending end sends the information transfer request and the transfer time information to the intelligent contract end, and determines whether the signature of the transfer time information is the same as the signature of the receiving end through the intelligent contract end, and when it is determined that the signature of the transfer time information is the same as the signature of the receiving end, it is verified that the sending end and the receiving end trust each other, and the target information can be sent to the receiving end through the intelligent contract end. This application guarantees not to introduce the third party through the block chain technique to make information transfer only go on between sending end and receiving terminal, intelligent contract end then is used for verifying whether can carry out information transfer between sending end and the receiving terminal, reduces the information transfer number of times, guarantees that target information shifts between as few terminals as possible, has guaranteed user information's security. Moreover, the signed transfer frequency information is used as the verification information, and the transfer frequency is updated after information transfer is completed every time, so that the signed transfer frequency information generated in every information transfer is different, and even if a private key of a sending end is stolen, a stealer cannot forge the verification information through the previously disclosed transfer frequency information and signature, and then the information of the stolen end is transferred out, and the safety of user information is further ensured.
It should be noted that the method of the embodiment of the present application may be executed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment, and the multiple devices interact with each other to complete the method.
It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results.
