Abstract

The invention discloses a method and device for dynamically encrypting data, computer equipment and storage media. The method includes obtaining random strings which are taken as the source of encryption keys to perform storing; performing specified digest operation on the specified characteristic information transmitted by data packets between servers; determining starting characters of the encryption keys selected from the random strings according to results operated by specified digests; starting from the starting characters to obtain the encryption keys from the random strings; performingencryption on to-be-sent data packets by using the encryption keys according to a predetermined encryption algorithm; and sending the encrypted to-be-sent data packets. The method enhances the security of data encryption.

Description

technical field [0001] The invention relates to the field of Internet information encryption, in particular to a method, device, computer equipment and storage medium for dynamically encrypting data. Background technique [0002] Today, when the Internet has penetrated into every corner of life, people perform various operations on the Internet every day. Among these operations, e-mail exchanges, online transactions, and other behaviors that require data security guarantees have absolute requirements for the reliability and security of data encryption. Therefore, data encryption technology has become an important part of the development of Internet technology today. [0003] In the existing data encryption technology applied in the Internet, the client and the server establish a connection to communicate, and the encryption key and decryption key used in the entire communication process are fixed as the key pair generated and distributed at the beginning of the communicatio...
