Issuer of digital certificates, used for encrypting communication and signing documents. See also digital certificates, digital signatures.
An internal entity or trusted third party that issues, signs, revokes, and manages digital certificates.
A certificate authority organization that issues digital certificates. The Certificate Authority usually does a background check on the organization applying for a digital certificate, in order to verify that the organization is who it claims to be.
(CA) A trusted entity that issues and manages digital certificates and ensures that the certificates are valid and current.
An organisation that issues and manages security certificates that are used to establish credentials and verify identities when performing electronic transactions. See also SSL.
A trusted company that will accept a public key, along with some proof of identity, and serve as a repository of digital certificates.
Network software that issues and manages security credentials and public keys for authentication and message encryption. As part of a public-key infrastructure (PKI), which enables secure exchanges of information over a network, a certificate authority checks with a registration authority (RA) to verify information provided by the requestor of a digital certificate. If the registration authority verifies the requestor's information, the certificate authority can issue a certificate. Based on the PKI implementation, the certificate content can include the certificate's expiration date, the owner's public key, the owner's name, and other information about the public-key owner. See also registration authority (RA).
Any party that can digitally sign a warrant (q.v.). The usefulness of CAs depends on the trust put in them by the receivers of the warrants.
An organisation authorised to issue certificates (as in CA).
A certificate authority manages security credentials for Web sites and other on-line transmissions.
A Certificate Authority (CA) is a third party which verifies the identity of merchants and their sites. The certificate authority issues a certificate (also called a digital certificate or an authentication certificate) to an applicant company, which can then put the certificate up on its site.
A trusted entity which performs the PKI functional roles of certificate issuer, certificate manufacturer, registrar and repository. The CA appends the certificate issuer's identity to the issued Digital Certificate and a Digital Signature using their Private Key. The Digital Certificate of the CA may be retrieved based upon the identity and its Public Key used to authenticate the issued Digital Certificate. (See ANS X9.57 and X9.79)
An organization that issues and validates unique digital certificates that are then used to create digital signatures and public-private key pairs. The CA ensures that the user granted the certificate is who they claim to be, often through the use of information supplied by a financial institution, such as a credit card company. Often the CA is a third party, but it doesn't have to be. In the case of many VPN solutions, they use their own internal CA and certificates.
An organization that issues digital certificates (digital IDs) and makes its public key widely available to its intended audience.
An entity that attests to the identity of a person or an organization. A Certificate Authority might be an external company such as VeriSign that offers certificate services or they might be an internal organization such as a corporate MIS department. The Certificate Authority's chief function is to verify the identity of entities and issue digital certificates attesting to that identity.
A third party organization that confirms the relationship between a party to the https transaction and that party's public key. Certification authorities may be widely known and trusted institutions for Internet-based transactions. Where https is used on a company's internal network, an internal department within the company may fulfill this role.
Certificate Authority (CA): issues, revokes, manages and digitally signs certificates (i.e. Globalsign). See also Certificate, Public Key Cryptography.

A Certificate Authority or CA, is a trusted third-party company that issues digital certificates. A digital certificate verifies that the user sending information is who they say they are and provides a means to encrypt closed two-way communication between the sender and the receiver of data.
A Certificate Authority is a trusted party that creates and issues electronic identities in the form of certificates to users. The trust in the Certificate Authority is the foundation of trust in the certificate as a valid credential and is dependent upon the measures taken by the Registration Authority to authenticate and validate that each user is what or who it claims to be prior to being issued a certificate. Certificate Authorities "sign" certificates with their digital signature.
(CA): A trusted third-party organization or company that issues digital certificates such as VeriSign, Inc. The CA "signs" the digital certificate verifying that the public key belongs to the specific company or individual. The CA makes its own public key readily available through the Internet. In AS2, the recipient of the message uses the CA's public key to decode the sender's digital certificate and verifies it was issued by the CA. The recipient can then obtain the sender's public key and identification information contained in the certificate. The recipient can use this information to send an encrypted reply message.
Entities that issue the digitally signed certificates containing information used to identify the user or site. When you accept a certificate signed by a given certificate authority, you are saying you trust that authority to have verified the identify of the person or site.
The entity or organization that attests using a digital certificate that a particular electronic message comes from a specific individual or system.
Service which manages security credentials for web-sites and other online transactions.

An organisation that signs the validity of SSL certificates.
An organization that issues certificates. A CA creates digital signatures and public-private key pairs. The CA guarantees the identity of the individual who is granted the unique certificate and guarantees the services that the owner is authorized to use, to issue new certificates, and to revoke certificates that belong to users and organizations who are no longer authorized to use the services. The role of the CA s to authenticate the entities (users and organizations) involved in electronic transactions. Because the CA guarantees that the two parties that are exchanging information are really who they claim to be, the CA is a critical component in data security and electronic commerce.
A mutually trusted organization that issues certificate s. Before issuing a certificate, the certificate authority requires you to provide identification information. Versign, Inc. is a recognized certificate authority.
n. In e-commerce, an organization that issues certificates. The CA authenticates the certificate owner's identity and the services that the owner is authorized to use, issues new certificates, renews existing certificates, and revokes certificates belonging to users who are no longer authorized to use them.
In computer security, an organization that issues certificates. The certificate authority authenticates the certificate owner's identity and the services that the owner is authorized to use. It also manages the issuance of new certificates and revokes certificates from unauthorized users who are no longer authorized to use them. A certificate authority is considered to be trusted when a user accepts any certificate issued by that certificate authority as proof of the certificate owner's identity.
A trusted third-party organization or company that issues digital certificates used to create digital signatures and public-private key pairs. The CA guarantees the identity of the individual who is granted the unique certificate.
A trusted third-party organization or company that issues digital certificates used to create digital signatures and public-private key pairs. CAs are a critical component in data security and electronic commerce because they guarantee that the two parties exchanging information are really who they claim to be.

A trusted third party that serves authentication infrastructures or organizations and registers entities and issues them certificates
A trusted entity that issues a certificate after verifying the identity of the person or entity the certificate is intended to identify. A CA also renews and revokes certificates and generates a list of revoked certificates at regular intervals. CAs can be independent third parties (such as the CAs listed at Certificate Authority Services) or a person or organization using certificate-issuing server software (such as iPlanet Certificate Management System). See also certificate revocation list (CRL).
A trusted entity that issues a certificate after verifying the identity of the person or program or process that the certificate is intended to identify. A CA also renews and revokes certificates, and at regular intervals generates a list of revoked certificates.
A trusted third part that authenticates digital signatures, verifying the identities of parties to electronic documents just as notaries have traditionally verified the identities of signatories to written documents. In an e-commerce "Public Key Infrastructure" (2PKI"), certificate authorities maintain repositories of digital signature certificates and bear the risk if there is an erroneous authentication. Certificate authorities are regulated in a number of states in the USA and have yet to reach the UK or the EU but will be with us shortly. Return to the top
A company that guarantees the identity of the holder of a digital certificate. A certificate is attached to a message or Web page and can be used to guarantee the authenticity of information.
This is the service a bank provides that digitally signs public keys sent to it by a web browser or by the merchant's server software. It issues and validates digital certificates associated with SET transactions.
Company or organization that sells and issues authentication certificates. You may purchase an authentication certificate from a Certification Authority that you trust. Also known as a CA.
A certificate authority (CA) is a trusted third party that certifies the identity of other entities such as users, databases, administrators, clients, and servers. The certificate authority verifies the user's identity and grants a certificate, signing it with one of the certificate authority's private keys.
Government to Organisation (G2O)
A trusted entity that issues a certificate after verifying the identity of the person or entity the certificate is intended to identify. A CA also renews and revokes certificates and generates CRLs. The entity named in the issuer field of a certificate is always a CA. Certificate authorities can be independent third parties or a person or organization using certificate-issuing server software (such as Certificate Management System). Certificate Management System makes it possible to divide the role of a CA among one or more Registration Managers, which handle most or all interactions with certificate owners, and a Certificate Manager, which issues certificates.
The party that issues a Secure or Security Certificate. CGI: Common Gateway Interface - the specification for how an HTTP server should communicate with server gateway applications so that a website can offer interactive sites rather than only static texts or images. Generally a CGI program is a small program that takes data from a web server and performs a function, like putting the content of a form into an e-mail message, or turning the data into a database query. Many times you can see that a CGI program is being used by seeing "cgi-bin" in a URL, but this is not always the case. cgi-bin: Refers to the name of a directory on a web server where CGI programs are stored. The "bin" part of "cgi-bin" is an abbreviated version of the word "binary", because once upon a time, most programs were referred to as "binaries". In real life, most programs found in cgi-bin directories are text files -- scripts that are executed by binaries located elsewhere on the same machine.
A CA is a company or organisation that issues Digital Certificates after validating an individual's or organisation's identity.
A trusted company or government agency that provides certificates digitally signed with its private key. The certificate can be decrypted using the certificate authority's public key. The certificate authority verifies that an organization is who it claims to be before issuing a certificate.
A trusted third party whose purpose is to sign certificates for network entities that it has authenticated using secure means. Other network entities can check the signature to verify that a CA has authenticated the bearer of a certificate.
A company trusted by a browser maker that issues digital certificates that are supposed to guarantee that the company is what it claims to be for use in encrypted digital transactions though SSL. Verisign is the biggest certificate authority.
One of several safeguards for secure e-commerce and overall data transfer, a certificate authority is a third-party organization that creates digital certificates. The certificate authority guarantees a user's identity and issues public and private "keys" for message encryption and decryption. Much like a notary, the certificate authority guarantees that a user is the person he or she claims to be, and that the provider of the information is who the user believes he or she is accessing. Certificate authorities issue security certificates used in SSL (secure) connections.
An organisation issuing and managing Certificate s or Public key s and Private key s to individuals or organisations together with identification information. CAs make public keys available and also issue Private key
A company that issues and manages security credentials; that is, certificates. The CA verifies the information provided by the requestor of the certificate. If the CA successfully verifies the requestor's information, the CA then issues a certificate to the requestor. See certificate.
A trusted entity that issues certificates to end entities and other CAs. CAs issue CRLs periodically, and post certificates and CRLs to a repository.
Certificate authority is a trusted third party that authenticates users and issues certificates. In addition to establishing trust in the binding between a user's public key and other security-related information in a certificate, the CA digitally signs the certificate information using its private key.
A CA (certificate authority) is an authority in a network that issues and manages security credentials and public keys for message encryption and decryption.
A trusted third party that certifies that other entities--users, databases, administrators, clients, servers--are who they say they are. When it certifies a user, the certificate authority first seeks verification that the user is not on the certificate revocation list (CRL), then verifies the user's identity and grants a certificate, signing it with the certificate authority's private key. The certificate authority has its own certificate and public key which it publishes. Servers and clients use these to verify signatures the certificate authority has made. A certificate authority might be an external company that offers certificate services, or an internal organization such as a corporate MIS department.
An entity trusted to sign digital certificates and, therefore, attest to the identity of other authorized users.
An office, bureau, or service that issues security certificates.
(CA) a trusted third party (TTP) who creates certificates that consist of assertions on various attributes and binds them to an entity and/or to their public key. An entity responsible for authorising and issuing digital certificates.

A certificate authority is a private company that issues digital certificates. Certificate Authorities conduct a thorough background check on the validity and credit of a business, as well as vouch for a business' right to use their company name and Web address.
A Certificate Authority (CA) is an organization that issues and manages security credentials and Keys for message encryption and decryption. As part of Public Key Infrastructure (PKI), the CA provides certificates ( Keys) to Issuers. The Keys are used to encrypt, sign and secure Electronic Payment Services (EPS) transactions.
Issues Certificates to Government Agencies, SecureMail Service Providers and Businesses that have an accredited Gateway.
A trusted third party that can assure the identity of others when using security systems like SSL certificate authority registers the digital identity of a site or individual, and lets you confirm manually or automatically that someone you're interacting with -- say, over a secure Web connection -- is who he appears to be.
A trusted organization that acts as an issuer and repository for digital certificates. A certificate authority accepts a userâ€(tm)s public key along with some proof of identity. It then issues a certificate for that user. Others can then verify the authenticity of that userâ€(tm)s public key with the certificate authority. See Certificate, Digital Signature, PKI
(CA) An organization, such as a financial institution or trusted third party, that issues and manages the authenticity of digital certificates for use in electronic commerce.
Manages digital certificate application, certification (authentication of the applicant), issuance and revocation. A CA is similar to a Key Distribution Center (KDC) which acts as a trusted third party for cryptographic keys except that a KDC is entrusted with secret keys and a CA only has to keep its private key secret in order to protect the digital certificates it issues for public keys.
In cryptography, a certificate authority or certification authority (CA) is an entity which issues digital certificates for use by other parties. It is an example of a trusted third party. CAs are characteristic of many public key infrastructure (PKI) schemes.
