What does PKI stand for?

PKI stands for Public Key Infrastructure, which is a framework used to secure and manage digital communication and transactions over the internet. It involves the use of Public Key Cryptography, where a pair of keys (a public key and a private key) are utilized to encrypt and decrypt data, ensuring that information can only be accessed by intended recipients.

Public Key Infrastructure encompasses the policies, hardware, software, and people involved in managing digital certificates and public-key encryption. This infrastructure is essential for enabling secure electronic exchanges, providing services such as authentication, data integrity, and non-repudiation. With PKI, entities like organizations and individuals can establish their identity online, facilitate secure communication, and manage access to sensitive information.

The other options inaccurately represent the concept of PKI. Private Key Integration and Private Key Infrastructure do not reflect the nature of public key systems. Public Key Integration, while partially related, does not encompass the complete framework and roles that PKI includes. Therefore, understanding that PKI specifically refers to Public Key Infrastructure is crucial for anyone dealing with secure communication technologies.
