What is Public Key Infrastructure (PKI)?
Public Key Infrastructure (PKI) is a framework that provides a secure environment for electronic transactions and communication. It uses a combination of hardware, software, and policies to manage the creation, distribution, and revocation of digital certificates, ensuring secure data exchanges. PKI plays a crucial role in:
- Authentication: Verifying the identity of individuals or systems.
- Encryption: Ensuring the confidentiality of data during transmission.
- Data Integrity: Guaranteeing that data is not altered during transit.
- Non-repudiation: Preventing denial of sent or received messages.
PKI enables the secure use of encryption and digital signatures, making it a cornerstone of cybersecurity.
