An information security method and procedure

Abstract

An information security method and procedure relates to the field of computer software, network communications and information security technology, especially used for information security of instant messaging, e-mail and other edited texts. By cipher algorithm procedure and / or by cipher device hardware, complete or selective instant encrypt or instant decipher is performed to text message in the current editing text, so as to instantly replace it from plaintext to ciphertext or from ciphertext to plaintext and present in the same window; when the cursor is stopped at the read-only ciphertext, it can be instant read and the corresponding plaintext can be presented; furthermore, it can be driven by a same shortcut operation, so that the encryption and decryption can be alternately performed, plaintext and ciphertext can be alternately replaced and displayed; a practical information security program is also designed, which is used in synergy with the object program and runs independently, to realize real-time encryption and decryption to information. The invention is general-purpose, convenient, flexible and efficient, and has universality because of its informality in the device hardware and no limitation to the application software.

Description

technical field [0001] The invention relates to the technical fields of computer software, network communication and information security. Background technique [0002] Information often involves the confidentiality, privacy and property of organizations and individuals; in the network environment, especially in the Internet environment, these important information are easily stolen and leaked, resulting in irreparable losses. Therefore, information confidentiality has become a common concern of people. The basic technical idea of ​​information security is to use a certain cryptographic algorithm combined with a key to encrypt the plaintext of the information that needs to be kept secret to generate garbled ciphertext. There are many kinds of current practical cryptographic algorithms, some of which have already become technical standards, such as DES, AES, RSA, DSA and so on. Information is most likely to be leaked in the input, storage and transmission links, and the enc...

Problems solved by technology

This invention emphasizes the flexibility of selection, but there are two disadvantages: first, the operation efficiency is low, and after the selection, it needs to be marked and a password is set;

If this method is extended to timely communication, there will be embarrassment of slow chat response and helplessness to cover up input information

Moreover, the cost of delayed encryption is only suitable for embedding in the target mailbox service program, and it is not easy to implement as an independent and universal encryption program that not only serves the mailbox program
