Problems solved by technology

Since the public key cannot uniquely determine the identity of the client, during the transaction, the client will deny that the transaction was initiated by the client, resulting in transaction repudiation disputes, making the transaction impossible to proceed normally, and further reducing the user experience of both parties in the communication

Embodiment Construction

[0052] specific implementation plan

[0053]In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] An embodiment of the present application provides an anti-repudiation method for transaction information, where the transaction information is transaction information between a server and a client, and the method is as follows: figure 1 shown, including the following steps:

[0055] Step 101, the client generates request information and a request identifier.

[0056] In this embodiment of the application, the request information is the request content to be sent by the client, including: service request, transaction request, etc. The request ID is the serial number generated by the client for each transaction, for example, 20191218123456. Among them, "20191218" represents the request time, and the re...

Abstract

The invention discloses an anti-repudiation method of transaction information, a client and a server, and the method comprises the steps: generating a client private key, a client public key, requestinformation and a request identification, transmitting the client public key to the server, and receiving a server public key generated by the server; encrypting the request identifier and the requestinformation by using a first symmetric key to generate a first ciphertext; encrypting the first symmetric key by using the client private key to generate a second ciphertext; sending the first ciphertext and the second ciphertext to the server; and receiving and decrypting the information returned by the server by using the server public key to obtain the request identifier and the response information. According to the method provided by the invention, repudiation of a client or a server can be prevented, so that normal transaction is ensured, and the user experience of two communication parties is improved.

Description

technical field [0001] The application relates to the field of communication technology, and discloses a transaction information anti-repudiation method, a client terminal, and a server. Background technique [0002] In the Internet environment, when the content is transmitted through the HTTP protocol, it is transmitted in plain text. If it is illegally intercepted, it will cause content leakage. Since the identity information of the client cannot be confirmed, criminals can use illegally intercepted information to conduct transactions. [0003] Usually, the client and the server use the public key to encrypt the information to be sent when communicating, and then send the ciphertext to the other party. Since the public key cannot uniquely determine the identity of the client, during the transaction, the client will deny that the transaction was initiated by the client, resulting in transaction repudiation disputes, making the transaction impossible to proceed normally, an...
