1. Public Key Infrastructure (PKI) Definition
Public Key Infrastructure (PKI) is a framework of policies, technologies, and procedures used to manage digital certificates and public-key encryption. PKI enables secure communication and digital transactions by ensuring that users and systems can trust each other’s identities. PKI relies on Certification Authorities (CAs) to issue and manage digital certificates, which link public keys to the identities of individuals or organizations.
2. Why Is PKI Important?
- Trust and Security: PKI establishes trust by verifying the identities of users, systems, and organizations through digital certificates, enabling secure communication and transactions.
- Data Encryption: PKI provides the infrastructure needed for public key encryption, ensuring that sensitive data is protected during transmission and storage.
- Authentication: PKI ensures that the entities involved in digital transactions are who they claim to be, providing authentication through digital certificates.
- Compliance: PKI helps organizations comply with legal and regulatory requirements for data security, encryption, and digital signatures.
3. Key Components of PKI
- Certification Authority (CA): A trusted entity that issues and manages digital certificates, verifying the identity of users and linking them to their public keys.
- Digital Certificates: Certificates issued by a CA that verify the identity of users or systems and associate them with their public keys.
- Key Pairs: PKI relies on the use of public and private key pairs for encryption, authentication, and digital signatures.
- Certificate Revocation List (CRL): A list maintained by the CA that identifies digital certificates that are no longer valid or have been compromised.
