Target Domain, and click the Security link.To an organization, e-mail is arguably the most important Internet service. To configure the Domain PKI settings, use the WebAdmin Interface to open the Domain Settings page for the They includeĪ Private Key associated with the Domain and Certificates containing the matching Public Keys. Posseses a Private Key matching one of the Certificates used for encryption.ĭomain PKI Settingss Each CommuniGate Pro Domain has its own PKI settings. Multiparty Encryption An encryption method used to send data to parties with known Certificates.Ī single encrypted messages can be independently decrypted by any party that Self-Signed Certificates can be trusted only if other parties explictily include them into The Self-Signed Certificate contains the party Public Key and is signed using the The Subject and Issuer of such a CertificateĪre the same. Self-Signed Certificate A Certificate issued by a party for itself. If those Certificates are sent together with the X own Certificate, issued by Y, then theseĬertificates may be accepted by all parties that trust Y. In this case Certificates issued by X won't be widely accepted, but Some Authority X may be not widely accepted as a "trused one", but its Certificate may be issuedīy a more widely trusted Authority Y. Trusted by all client computers running these operating systems.Īuthority Chain A set of Issuer Certificates for a certain Certificate. Several Root Authorities into the client Trusted Authorities databases, making Root Authorities Root Authorities Globally recognized Certificate Authorities. Modern operating systems allow users to securely maintain Trusted Authorities databases on their desktops. The "trusted authority" list, and that the Certificate Signature can be verified using that When a party receives any Certificate, it can check if the Certificate Issuer is included into Each list element contains the name ofĪ "trusted authority" and its Public Key. Trusted Authorities A list individually maintained by a communication party.

Each certificate generated byĪ certain Issuer has a unique serial number. Issuers are also called Certificate Authorities. Issuer A party that issues Certificates for other parties, siging them with the Private Key of This data block is signed by the Issuer.Ĭertificates play the role of Digital ID cards.

The Public Key of the owner, the name of the Certificate Issuer, the serial number of theĬertificate, and some additional data elements. The Signer to decrypt the Signature and to compare the resulting Data Dagest with theĬertificate A data block with containing the name of the Certificate owner (called Certificate Subject), A party receiving Signed DataĬan verify that the data block has not been modified in transit by using the Public Key of Signed Data A data block with attached Signature of that block. To the original (usually larger) data block.ĭata Signature A Digest of the Data block encrypted using the Private Key of the Signer. Public Keys are usualy distributed in the form of Certificates.ĭata Digest A relatively small block of data calculated by applying a special digest function It is assumed that Public Key can be learned by anyone, including hostile entities. Public Key A block of data (a large binary number) generated together with the Private Key.Įach party taking part in secure communications can and should distribute its Public key This key should never be transferred between communication parties. Private Key A block of data (a large binary number) generated using one of the PKI algorithms.Įach party taking part in secure communications should keep its Private Key securely.
The Public Key Infrastructure (PKI) is the technology based on this asymmetric cryptography. Information encrypted with the "public key" can be decrypted using the matching "private key". "private key" can be decrypted by anyone who knows the matching "public key", and any Keys must be generated together using special algorithms. This type of cryptography is called symmetricĪn alternative cryptography method is based on key pairs - a "private key" and a "public key". InformationĮncrypted using some "secret key" can be decrypted by anyone who knows the encryption methodĪnd posses the same "secret key". Regular ("classical") cryptography methods use data blocks called "secret keys". Assigning a Certificate Authority Chain.CommuniGate Pro: Public Key Infrastructure
