Public key infrastructure. A public key infrastructure ( PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
Public key certificate. In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [ 1][ 2] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the ...
Certificate authority. In cryptography, a certificate authority or certification authority ( CA) is an entity that stores, signs, and issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions ...
PEAP is similar in design to EAP-TTLS, requiring only a server-side PKI certificate to create a secure TLS tunnel to protect user authentication, and uses server-side public key certificates to authenticate the server. It then creates an encrypted TLS tunnel between the client and the authentication server. In most configurations, the keys for ...
X.509. In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web. They are also used in offline applications, like ...
The Online Certificate Status Protocol ( OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. [ 2] It is described in RFC 6960 and is on the Internet standards track. It was created as an alternative to certificate revocation lists (CRL), specifically addressing certain problems associated with ...
Electronic authentication. Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. [ 1] Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works.
Certificate-Based Authentication: This form of authentication prioritizes the use of digital certificates, typically an individual's driver's license or a passport as a form of an electronic document. A certification authority will then prove ownership of a public key to the owner of that digital certificate.
