This article mainly introduces the analysis of the principle of software digital signature, the sample code in the article is very detailed, has a certain reference value, interested friends must read it!

What is a digital signature? A digital signature is a kind of physical signature similar to that written on paper. However, it uses a technical implementation in the field of public key encryption, which is mainly used to identify a method of information. What are its main functions? In order to ensure the integrity of the transmission of a message. Let's talk about digital signature tools.

I. Digital signature tool

One of the functions of a signature is simply to prove that some information is really written by me that I agree with. Others cannot pretend to be me or carry out a forgery. I cannot deny that this signature is not mine; all our documents have to sign and press handprints and so on, which can be proved to be yours! Everyone is unique, even if you have to imitate, you can now tell whether it is you or not by certain armor. A digital signature is the same reason as this. What does the digital signature tool rely on to guarantee its two characteristics that cannot be forged and cannot be denied? That is an encrypted system of a public key.

II. Principle of software digital signature

Now that we know what a digital signature is, let's take a look at the principle of software digital signature. The so-called digital signature refers to some data attached to a related data unit, or a password transformation made by the data unit. This transformation of data allows a receiver of the data unit to confirm a source of the data unit and an integrity of the associated data unit and to protect the data. And then prevent malicious forgery by some people. Some of his related applications will also involve legal issues. One of the characteristics of his principle is that he can identify the power, his integrity, and can not be denied.

Third, drive signature tool

There are three common implementation methods of digital signature, that is, a password generation method, a token calculation method, and a related verification method. The driver signature tool refers to a digital signature tool for the driver. What if I don't? The first step is to open the start of your computer and click run. Then enter a gpedit.msc. After that, uh, find the administrative template below the user configuration and double-click, and then double-click to expand the installation of a driver. Then select enable. Enabled. Finally, when we click finish, it is recommended that you set the options that are set to ignore and set them as warnings to enhance the security of your system.

There are some systems when you install some drivers, he will require a digital signature by default, if not, he will not be able to install and use them normally. Therefore, it requires us to understand the knowledge related to digital certificates, and not to update a security issue of our system in a timely manner.

The above is all about the analysis of the principle of software digital signature, thank you for reading! Hope to share the content to help you, more related knowledge, welcome to follow the industry information channel!
