Embodiment Construction

[0024] In order to make the purpose, technical solution, design method and advantages of the present invention clearer, the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] like figure 1 As shown, the first aspect of the present invention provides a method for reciprocally encrypting data, comprising the following steps:

[0026] S1: The encryption machine forms two pairs of key pairs through the encryption algorithm, public key A, private key A, public key B, and private key B;

[0027] S2: Send two sets of key pairs to the server at the same time;

[0028] S3: The storage receives the public key A and the private key B returned by the server;

[0029] S4: The server stores the public key B and the private key A into the database;

Abstract

The invention belongs to the technical field of data encryption, and particularly discloses a method and system for reciprocally encrypting data, equipment and a storage medium. The method comprises the following steps: a cipher machine randomly forms two key pairs through an encryption algorithm, namely a private key A, a public key A, a private key B and a public key B, stores the public key A and the private key B in a local user side, and stores the private key A and the public key B in a server; the public key A encrypts a file; after receiving a ciphertext, the server decrypts the ciphertext through the private key A; the server encrypts the file through the public key B, and a client decrypts the file through the private key B when the receiving the ciphertext. The invention provides a reciprocal storage index query data mode, so that the data transmission process is effectively prevented from being tampered and decoded. The data security transmission performance and storage performance are effectively improved.

Description

technical field [0001] The present application belongs to the technical field of data encryption, and in particular relates to a method, system, device and storage medium for reciprocally encrypting data. Background technique [0002] With the popularity of computer technology applications, computers play a pivotal role in people's production and life. During the use of a computer, various challenges are often encountered, among which, the security of various files on the computer is a very big challenge. [0003] In order to ensure the security of files, various effective encryption and decryption techniques have been developed. In the prior art, in order to ensure the security of the file, various encryption algorithms are often used to encrypt the file, so as to prevent the file from being illegally tampered with and ensure the security of the file. However, in the process of interaction between users and the system, it also brings a lot of inconvenience to users. The m...
