Digital signature certificate is a kind of security certificate, which has many functions. Many enterprises will choose to configure this kind of certificate when they communicate with each other. But what are the basic reasons for using digital signature certificates in communications?

The first reason is to protect the integrity of information: although it is a network age, it is good to use the network to transmit information. However, nowadays there are many network hackers, so the information is easy to be tampered with when it is transmitted, and the integrity of the information can not be guaranteed at this time. Digital signature certificate can provide security to a certain extent, and can effectively encrypt the transmitted information, so it can effectively protect the integrity of the information. At this time, the information will not be tampered with during transmission, so many enterprises will consider configuring digital signature certificates once they have important information to transmit.

The second reason is to prevent some repudiation: in the process of file transfer in China, the word repudiation actually refers to the non-recognition of actions related to the transmitted information. After receiving the message, some third parties will say through denial that they have not received the message. Digital signature certificates can prevent this kind of repudiation to some extent. Because the receiver of the information can show his signature to others to see the source of the relevant information, and then better protect the security of the information.

The third reason is that information authentication can be better: when communicating, some information will not be within the authority when it is transmitted, which will lead to unsafe transmission of information. However, a digitally signed certificate can change that. When there is a digital signature certificate, the information can be better authenticated. In this case, the security is very high, and the information can be transmitted securely.

The above three basic reasons are not only the important reasons for the emergence of digital signature certificate, but also the basic function of this kind of certificate. Know that the role of digital signature certificate is more, now many enterprises will apply for the certificate, and then directly configured to the server of the website. However, the application for a digital signature certificate is actually required, and it is generally necessary to apply in a formal place.

CA is an authoritative certification authority, and all kinds of certificates issued by this authority are very secure. Therefore, when you apply for a digital signature certificate, you can easily protect information security by choosing to apply in CA, an authoritative certificate authority.
