Public Key Infrastructure (PKI) contains four components:
certificate authority (CA), registration authority (RA), RSA, and digital certificates
. Who is responsible for issuing certificates? The certificate authority (CA) is responsible for issuing certificates.
Which PKI component contains a list of all the certificates that have been revoked?
A certificate revocation list, more commonly called
a CRL
, is exactly what it sounds like: a list of digital certificates that have been revoked. A CRL is an important component of a public key infrastructure (PKI), a system designed to identify and authenticate users to a shared resource like a Wi-Fi network.
What are the components of PKI?
So how does PKI authentication work? There are three key components:
digital certificates, certificate authority, and registration authority
.
What is PKI quizlet?
PKI.
Public Key Infrastructure
– an arrangement that binds public keys with respective identities of entities. – a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. CA.
Which of the following is not a component of a PKI system?
The components of Public Key Infrastructure are CA, RSA, RA, and digital certificates. Therefore,
XA
is not a component of public key infrastructure (PKI).
What is a PKI system?
Public key infrastructure
(PKI) governs the issuance of digital certificates to protect sensitive data, provide unique digital identities for users, devices and applications and secure end-to-end communications.
Where is PKI used?
PKI is used in a number of different ways. It’s used in
smart card logins
, encryption of XML documents, secure email messaging and client system authentications. In all those cases where data security is of paramount importance, PKI is used.
What is the process of revocation in PKI?
Certificate revocation ensures that
the PKI system adds a certificate’s serial number to a blacklist
, called the certificate revocation list (CRL), when a PKI user’s private key is compromised.
Which list is list of certificates that are invalid?
In cryptography, a certificate revocation list (or CRL) is “a list of digital certificates that have been revoked by the issuing certificate authority (CA) before their scheduled expiration date and should no longer be trusted”.
What is OCSP response?
OCSP stands for Online Certificate Status Protocol and is
used by Certificate Authorities to check the revocation status of an X. 509 digital certificate
.
What is the role of a CA in a PKI quizlet?
A CA is an organization or entity that issues and manages digital certificates and is
responsible for authenticating and identifying users who participate in the PKI
. … A CA server can be set up to act as the manager of certificates and the user’s public keys.
What is the role of a CA in a PKI?
A Certification Authority to issue certificates
– A trusted CA is the only entity that can issue trusted digital certificates. This is extremely important because while PKI manages more of the encryption side of these certificates, authentication is vital to understanding which entities own what keys.
What is the main function of TPM hardware chip?
TPM (Trusted Platform Module) is a computer chip (microcontroller) that
can securely store artifacts used to authenticate the platform (your PC or laptop)
. TPM (Trusted Platform Module) is a computer chip (microcontroller) that can securely store artifacts used to authenticate the platform (your PC or laptop).
What is PKI component verification?
A PKI is a system for the creation, storage, and distribution of electronic certificates(Digital Signature) which are
used to verify that a particular public key belongs to a certain entity
. …
What type of certificate is most often used in modern PKI?
Secure Web Sites – HTTPS
The most familiar use of PKI is in
SSL certificates
. SSL (Secure Sockets Layer) is the security protocol used on the web when you fetch a page whose address begins with https: . TLS (Transport Layer Security) is a newer version of the protocol.
What are the components of a certificate?
The certificate has a
number of attributes
, such as usage of the key, Client authentication, Server authentication or Digital signature and the public key. The certificate also contains the subject name which is information identifying the owner.
