Which of the following is used to validate and in some cases revoke certificates?
A public key infrastructure (PKI) contains software hardware and policies that allow digital certificates to be created, validated, or revoked. A digital signature provides integrity, authentication, and non-repudiation in electronic mail. A PKI typically consists of the following components: certificates, a key repository, a method for revoking certificates, and a method to evaluate a certificate chain, which security professionals can use to follow the possession of keys.
Pretty Good Privacy (PGP) is an email encryption system. PGP uses a web of trust to validate public key pairs. In a web of trust model, users sign their own key pairs. If a user wants to receive a file encrypted with PGP, the user must first supply the public key.
Post Office Protocol (POP) is a client email program. It is used to retrieve email from the email server.
Dynamic Host Configuration (DHCP) is a protocol that allows network administrators to centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization’s network. DHCP can automatically assign a new IP address when a computer is plugged into a different location on the network.
