In this article, we are going to delve deep into knowing the basics of Public Key Infrastructure.

There are many tools like Keyfactor that provide Cyber Security certifications. So, without wasting any further time, let us take a brief look at what PKI actually is.

What Does The Term PKI Mean?

In simple words, PKI is the term that focuses on everything that establishes and runs public key encryption. Public Key Infrastructure is one of the most common types of Internet encryption that deals with Cybersecurity.

It is actually installed on all web browsers to ensure that the traffic of the website is coming from a secure place. Organizations also use PKI to secure their internal communications.

The whole concept of PKI revolves around cryptography; it ensures that proper security is provided to websites. Keep in mind that these keys are not a part of the process of encryption; they just help to authenticate the true identity of the parties or devices. They are just certificate givers.

What Are PKI Certificates?

PKI certificates are nothing but online documents that work like digital passports. They are basically given to websites or entities that want to join the PKI-secured conversation. PKI certificates are not just random authentications, as they can contain a significant amount of data.

One of the top important pieces of information that a certificate includes is the website’s or entity’s public key; the certificate is only the medium through which the key is shared.

Then comes the part of authentication. Here, the certificate comes with an attestation from a reliable source that the entity or website is who they declare to be. Let us look at some of the key elements of PKI certificates to get a better understanding.

1. Registration Authority –

The registration authority is the single most important element in the Public Key Certificate. It confirms the identities of those asking for digital certificates.

2. Certificate Authority –

The certificate authority signs the entities with its public key and issues digital certificates.

3. Certificate Policy –

This certificate policy outlines all the PKI procedures; it helps outsiders judge the authenticity of the website.

4. Certificate Database –

The Database stores the metadata and certificates until the license expires.

Now that you know the basis of PKI and PKI certificates, let us take a look at the uses of PKI.

Different Types Of Public Key Infrastructure (PKI)?

Basically, PKI (public key infrastructure) includes a system consisting of technologies, policies, and procedures. With the help of PKI, you can create, manage, and use public keys and digital certificates.

Generally, PKI falls under the basics of cybersecurity. Actually, it helps systems to secure communication and data transfer. Additionally, it also helps the system to establish user identity, services, and devices.

The following are the ways through which PKIs help you ensure cybersecurity in your organization:
