Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in the current technology, the information receiving end and the sending end determine an encryption algorithm for the subsequent interaction process in advance before information interaction, and then use this established encryption algorithm in the subsequent process. The algorithm is easy to be deciphered and the information security is low due to encrypted communication. In view of this technical problem, an information processing device and method, and an information processing device and method are provided.

[0052] In order to solve the problem that in the current technology, the two sides of the information exchange always carry out encrypted communication based on the mechanism of the pre-agreed encryption method, which leads to low information security and is easy to be cracked by an illegal third party in the long-term communication process, an information processing method is proposed method, please combine figure 1 :

[0053] S102. Select one of multiple encryption methods to encrypt the data to be sent to obtain encrypted information.

[0054] The data to be sent may include the information required for information interaction between the sender and the receiver. For example, when the APP on the mobile terminal needs to interact with the server, the mobile terminal as the sender may need to send some request data to the server to request The server provides corresponding services, such as payment service, page refresh service, identity authentication service, etc. The raw d...

[0068] This embodiment provides an information processing method, which is used for an information receiving end to decrypt the information encrypted by using the information processing method provided in the first embodiment. In order to make those skilled in the art understand the advantages and details of the information processing method in this embodiment, the following combination figure 2 Be explained:

[0069] S202. Receive the encrypted information and the identification information of the encryption method transmitted by the sending end.

[0070] Since the sending end may send encrypted information and identification information separately using different communication links and different communication methods, the receiving end may also need to receive encrypted information and identification information separately. Now suppose that the sender transmits the encrypted information and identification information to the receiver in the form of a data message, and the ...

[0083] This embodiment provides an information processing method. On the basis of combining the first embodiment and the second embodiment, this embodiment will describe the aforementioned information processing method in detail from the interaction process between the sending end and the receiving end. Please refer below image 3 :

[0084] S302. The sending end digitally signs the original data according to a preset rule to obtain first signed data.

[0085] Digital signature, also known as public key digital signature and electronic signature, is a method similar to ordinary physical signature written on paper, but it uses the technology in the field of public key encryption to identify digital information.

[0086] The data to be sent includes the original data that the sender actually needs to send to the receiver. For example, in the data to be sent by the mobile terminal to the server through the APP, the included original data may be the request data generated accordi...

Abstract

The invention discloses an information processing method and device. The information processing method comprises the steps of pre-storing a mapping relationship between multiple encryption modes and encryption mode identification information at a sending end and a receiving end of information; selecting one of the multiple encryption modes for encrypting to-be-sent data by the sending end so as to obtain encrypted information and sending the encrypted information and the identification information corresponding to the selected encryption mode to the receiving end; and determining a decryption mode based on the received identification information and the pre-stored mapping relationship and decrypting by the receiving end. In the embodiment, the encryption mode for the information is not single and fixed, but is determined randomly from the multiple encryption modes in each interaction process, so that the encryption mode of the information has randomness and is difficult for a third party to break. The security of information interaction is improved, the privacy and benefit of two parties carrying out the information interaction are guaranteed and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the field of information security, and more specifically, relates to an information processing device and method. Background technique [0002] When the sender and receiver of the information interact with the sender, a considerable amount of sensitive information may be transmitted, which cannot be tampered with or known by a third party, such as APP (Application, application) and service In the process of interacting with the terminal, the issue of information security will inevitably be involved, because the user's property information may be involved in the interaction process. For example, when the user pays through the APP, he may need to provide his own bank account and account password. etc. Once these sensitive information are leaked or obtained and tampered by criminals, it will bring huge losses to the user's property. In addition, when a user uses some APP to interact with the server, the interactive inform...
