An encryption method and system based on time release

Abstract

The invention relates to an encryption method and system based on time release, which includes: generating a public-private key pair, encrypting information to be sent, setting a time-based signature and a time stamp T, and setting a protection time for the message. Decrypt the message. At the same time, the encryption process combines symmetric decryption and asymmetric decryption, which greatly improves the protection of information, effectively prevents the information from being cracked by a third party, provides verification of the message time, and proves the time validity of the message. Before the time, the message cannot be decrypted and used, which ensures the confidentiality of the message content and prevents the message content from being leaked in advance.

Description

technical field [0001] The field of the present invention is network encryption, specifically an encryption method and system based on time release. Background technique [0002] With the development of computer technology and network technology, people pay more and more attention to network security issues. For information transmission, encryption work is particularly important. The leakage of information may cause huge losses to enterprises. The existing encryption methods are mainly Symmetric encryption and asymmetric encryption are widely used by people, and their advantages and disadvantages are also different. However, the existing encryption technology still has the following problems: [0003] 1. The traditional encryption method does not add a time-based mark to the encrypted information. The message receiver cannot manage the validity period of the message, nor can it provide proof of the generation time of the message. A third party can attack the message storage ...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional encryption method does not add a time-based mark to the encrypted information. The message receiver cannot manage the validity period of the message, nor can it provide proof of the generation time of the message. A third party can attack the message storage module, forge the message, and tamper with the message time stamp;

[0004] 2. There is no organic combination of asymmetric encryption and symmetric encryption to achieve the effect of improving information confidentiality
