What is a Public Key Infrastructure (PKI)?
Public Key Infrastructure (PKI) is an essential aspect of internet security, a key element of data security. It's a structure of technologies and services, including cryptography and digital certificates, that provide a foundational layer of trust and security in online communications. But how does it do this?
In essence, PKI bridges the gap of trust in the digital landscape by assigning cryptographic keys to entities (such
as users, devices, or servers) in a network. This allows for secure exchange of data over potentially unsecured
networks, like the internet.
At the heart of PKI lies asymmetric cryptography, which uses a pair of keys - a private key, kept secret, and a
public key, openly available. Data encrypted with one key can only be decrypted with its paired key, allowing for
For example, if Alice wants to send a secure message to Bob, she uses Bob's public key to encrypt it. Bob, upon
receiving the message, decrypts it using his private key.
An important component of a PKI is the digital certificate. It's like a digital passport, providing proof of an
entity's identity and its public key. These certificates are issued by a trusted authority known as a Certificate
Authority (CA), and they prevent impostors from pretending to be someone else.
For the system to work, there needs to be a high level of trust in the CAs. All participants must trust that the CAs
verify identities accurately and manage certificates appropriately. This collective trust forms the basis of PKI.
You've probably used PKI without even knowing it. When you see a padlock icon next to the URL in your browser,
that's PKI in action! The website's digital certificate has been verified by your browser, ensuring the website's
identity and allowing for secure communication.
PKI is an intricate system that secures our online world, verifies identities, and facilitates trustworthy digital
interactions. Understanding it can help you better appreciate the security behind your everyday online activities.
