Description: Trust in Public Key Infrastructure (PKI) refers to the level of security and reliability that users place in the systems and components that facilitate the management of cryptographic keys. This trust is fundamental for the effective functioning of PKI, as it relies on users’ ability to verify the authenticity of public keys and the identity of the entities that hold them. PKI includes several elements, such as Certificate Authorities (CAs), which issue digital certificates, and Registration Authorities (RAs), which validate the identity of certificate applicants. Trust in PKI is built through security standards, certificate management policies, and auditing practices that ensure keys and certificates are issued and managed securely. Without this trust, users may hesitate to use online services that rely on cryptography, such as e-commerce, online banking, and secure communication. Therefore, trust in PKI is an essential pillar for digital security today, enabling users to interact securely in an increasingly interconnected environment.
