Description: Public Key Infrastructure Security (PKI) refers to the measures and protocols implemented to protect the integrity and confidentiality of a PKI. This infrastructure is essential for managing cryptographic keys and authenticating identities in digital environments. PKI uses a combination of hardware, software, policies, and procedures that ensure the creation, distribution, management, and revocation of digital certificates. These certificates are fundamental for establishing secure and reliable connections over the Internet, enabling data encryption and verifying the identity of the parties involved in a communication. The security of PKI relies on trust in Certificate Authorities (CAs), which are responsible for issuing and managing digital certificates. To maintain security, it is crucial to implement measures such as using robust cryptographic algorithms, physically protecting CA servers, and conducting regular audits. Additionally, proper key management, including secure storage and revocation or renewal when necessary, is vital to prevent unauthorized access and ensure trust in digital transactions.
