Public Key Infrastructure (PKI)
PKI is a set of hardware, software, people, policies, and processes required to create, manage, distribute, use, store, and revoke digital certificates. These certificates contain public keys that are used to encrypt data, ensuring secure and authenticated communication between two parties.
The main components of PKI include:
Certification Authority (CA): A trusted third party that issues and revokes digital certificates. The ca creates the certificate by verifying the identity of the certificate applicant and signing its public key with its own private key.
Registration Authority (RA): Responsible for collecting and verifying the identity information of certificate applicants. The RAs forwards this information to the CA to issue a certificate.
Repository: A secure location to store and distribute issued certificates. The repository can be online or offline, depending on the needs of the organization.
X.509 Public Key Certificate：X.509 is the standard for public key certificates. These certificates are issued by the CA and contain the certificate holder’s public key, their identity information, the CA’s signature, and other relevant details. X.509 certificates are widely used on the Internet for secure communication protocols such as SSL/TLS.
Public Key Infrastructure (PKI) is a framework used to manage digital certificates and public-key encryption, enabling secure communications over networks like the Internet. It involves issuing, managing, storing, and revoking digital certificates. X.509 is a standard defining the format of public key certificates, used in PKI systems to verify that a public key belongs to the user, computer, or service identity contained within the certificate.
PKI involves the issuance, management, storage, and revocation of digital certificates. PKI relies on a trusted authority, known as a Certificate Authority (CA), to issue and verify digital certificates. These certificates are essential for establishing secure connections, ensuring the confidentiality and integrity of data, and authenticating the identities of individuals, websites, and services involved in digital communications.
