What is CMP in security?


What is CMP in security?

The Certificate Management Protocol (CMP) is an Internet protocol standardized by the IETF used for obtaining X. 509 digital certificates in a public key infrastructure (PKI). CMP is a very feature-rich and flexible protocol, supporting any types of cryptography.

What is CMP request?

Certificate management protocol (CMP) is an internet protocol used to manage X. 509 digital certificates within a PKI. It is described in RFC 4210 and uses the certificate request message format (CRMF) described in RFC 4211.

What is CMPv2?

Certificate Management Protocol version 2 (CMPv2) can be used for certificate enrollment and reenrollment. CMPv2 supports RSA, DSA, and ECDSA certificates and is based on RFC 4210, Internet X. 509 Public Key Infrastructure Certificate Management Protocol (CMP) and RFC 4211, Internet X.

What is a PKI certificate?

Public Key Infrastructure (PKI) is a system of processes, technologies, and policies that allows you to encrypt and/or sign data. With PKI, you can issue digital certificates that authenticate the identity of users, devices, or services.

What does CMP mean?


Acronym Definition
CMP Comprehensive Management Plan
CMP Cardiomyopathy
CMP Civil Money Penalty
CMP Credential Maintenance Program (Green Building Certification Institute)

What is used to store and distribute a public key?

A public key infrastructure (PKI) is 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. A certificate policy stating the PKI’s requirements concerning its procedures.

What is CMP in telecom?

A heterogeneous server technology from Unisys that can run any combination of operating systems.

What is Scep used for?

Simple Certificate Enrollment Protocol (SCEP) is an open source protocol that is widely used to make digital certificate issuance at large organizations easier, more secure, and scalable. Using this protocol, SCEP servers issue a one-time password (OTP) to the user transmitted out-of-band (OOB).

What is external account binding?

External Account Bindings are used to associate your ACME account with an external account such as a CA custom database. This is typically not needed for most cert-manager users unless you know it is explicitly needed. External Account Bindings require two fields on an ACME Issuer which represents your ACME account.

Who needs a PKI certificate?

Health care providers need a Medicare Public Key Infrastructure (PKI) certificate to access online services. PKI certificates ensure that information you submit through the HPOS portal is secure. The Department of Human Services issue PKI certificates to individuals and organisations in the health sector.

Who signs the PKI certificate?

issuing CA
The certificate is signed by the issuing CA and the signature is attached in the certificate. X. 509 is the standard for the most commonly used digital certificate formats.

When was the Certificate Management Protocol ( CMP ) created?

RFC 2510 (CMP, 1999) The Certificate Management Protocol (CMP) is an Internet protocol used for obtaining X.509 digital certificates in a public key infrastructure (PKI).

Are there any other protocols like CMP or CMC?

CMP is described in RFC 4210. Enrollment request messages employ the Certificate Request Message Format (CRMF), described in RFC 4211 . The only other protocol so far using CRMF is Certificate Management over CMS (CMC), described in RFC 5273.

Who is the end entity of a CMP server?

A CMP Update is in preparation as well as a Lightweight CMP Profile focusing on industrial use. In a public key infrastructure (PKI), so-called end entities (EEs) act as CMP client, requesting one or more certificates for themselves from a certificate authority (CA), which issues the legal certificates and acts as a CMP server.

Which is the obsolete version of CMP for CRMF?

An obsolete version of CMP is described in RFC 2510, the respective CRMF version in RFC 2511 . A CMP Update is in preparation as well as a Lightweight CMP Profile focusing on industrial use.
