Problems solved by technology

[0004] However, in the current electronic transaction process, the transaction request sent by the transaction initiator to the bank is completely transparent to the bank, so the bank can learn the details of the transaction between the transaction initiator and the transaction responder based on the transaction details. Specifically, since the bank is a third-party device for both the transaction initiator and the transaction responder, the current electronic transaction method is difficult to ensure the confidentiality of transaction details between the transaction initiator and the transaction responder

Embodiment 1

[0034] figure 2 It is a flowchart of an electronic transaction method provided by an embodiment of the present invention. The electronic transaction method provided by the embodiment of the present invention is applied to the transaction initiator. Please refer to figure 2 , the specific steps of the electronic transaction method include:

[0035] Step S10: Generate the transaction details in the transaction request as N-particle state information, and combine the N-particle state information with the shared entangled state particles of the transaction initiator, bank and transaction responder to generate a mixed particle state.

[0036] Wherein, N is a positive integer.

[0037] It should be noted that in this step, the transaction details that need to be kept secret from the bank in the transaction request are generated into N particle state information, where N is a positive integer, which means that the transaction details can be converted into single particle state i...

Embodiment 2

[0044] On the basis of the above embodiments, the present invention also provides the following series of preferred implementation manners.

[0045] As a preferred embodiment, the value of N is specifically 2;

[0046] Correspondingly, the particle measurement is specifically the Bell measurement.

[0047] It should be noted that the value of N in this embodiment is 2, that is, in this embodiment, the transaction initiator device generates the transaction details information as two-particle state information, and then combines the two-particle state information with the shared entangled state particles, Generate hybrid particle states. This embodiment converts the transaction details information into two-particle state information, which has higher particle entanglement than single-particle state information, can relatively ensure the overall stability in the transmission process, and ensure the integrity and security of transaction details information. availability.

Embodiment 3

[0056] The technical solution of the present invention is described below through a specific scene embodiment. Not only this one, so this implementation does not specifically limit the present invention.

[0057] Assume that there are electronic transaction participants Peter (transaction initiator), Bob (bank end) and David (transaction response end). Peter needs to send a transaction request to David through Bob. First, the transaction details that need to be kept secret from Bob in the transaction request are converted into unknown two-particle state information, as shown below:

[0058] |φ M >=α|00> 12 +β|11> 12 , where |α| 2 +|β| 2 = 1;

[0059] Suppose Peter, Bob and David share the entangled W-state particles as follows:

[0060]

[0061] Among them, particles 1 and 3 are given to Peter, particles 2 are given to Bob, and particles 4 and 5 are given to David. The resulting five-particle state is:

[0062]

[0063] Peter performs a Bell measurement on parti...

Abstract

The invention discloses an electronic transaction method, device, system and a medium. According to the method, the confidentiality of transaction details between the transaction initiating end and the transaction responding end is relatively ensured. In addition, the invention further provides electronic transaction equipment, an electronic transaction system and a medium, and the beneficial effects are the same as described above.

Description

technical field [0001] The present invention relates to the field of electronic commerce, in particular to an electronic transaction method, equipment, system and medium. Background technique [0002] With the rapid development of the Internet, e-commerce is in a period of rapid development, so choosing an appropriate transaction method is very important for e-commerce transactions. [0003] figure 1 It is a schematic diagram of electronic transaction communication in electronic commerce in the prior art. Such as figure 1 As shown, in the current electronic transaction of e-commerce, it mainly involves the transaction initiator, the bank and the transaction response. When the transaction starts, the transaction initiator first initiates a transaction including the amount information and transaction details to the bank. According to the transaction request, the bank learns the object that needs to be traded with the transaction initiator, that is, the transaction responder...
