Encrypted Transmission Method Based on File Long-distance Encrypted Transmission System

Abstract

The present invention relates to the field of encryption technology, in particular, to an encrypted transmission method based on a file long-distance encrypted transmission system. The file long-distance encrypted transmission system includes a client for registering, logging in, batch sending and receiving files; Server, used for file transfer service, user management service, heartbeat detection function, log function, malicious attack prevention, secret key management and management interface service; after user registration, as long as you know the other party's account, you can send files to each other through the external network, file It will automatically encrypt and decrypt when sending and receiving, and does not require users to perform any encryption and decryption operations. It supports batch sending and batch receiving. The operation is simple and at the same time it can escort the data transmitted by the user, which better solves the problem of using the Android system. The problem of secure transmission of long-distance files.

Description

Technical field: [0001] The invention relates to the technical field of encryption, in particular to an encrypted transmission method based on a file long-distance encrypted transmission system. Background technique: [0002] In ancient wars, in order to keep information secret, simple transformations were often made to the content of letters. Cryptography, as the core technology to ensure information security, was widely used very early. Cryptography is always a fashionable topic in the means of ensuring data security. From the Caesar cipher a long time ago to the current symmetric cipher, to the asymmetric cipher, and the threshold cryptography technology in the future, cryptography is constantly developing and improving, and its value cannot be underestimated. In life, no matter you are working or studying, we always need to send and receive various files. Currently, there are many file transfer tools, such as Tencent QQ software. The file transfer function of Tencent Q...

AI Technical Summary

Problems solved by technology

The file transfer function of Tencent QQ software is very convenient, but the files transferred through Tencent QQ software are not encrypted. When files are maliciously intercepted, it may cause unnecessary losses to us

Of course, we can encrypt the file first, and then send the encrypted file to reduce the risk of data leakage, but the other party needs to know the password. It is also not conducive to our password management
