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, signing 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. Certificate A data block with containing the name of the Certificate owner (called Certificate Subject), The Signer to decrypt the Signature and to compare the resulting Data Digest with theĭata Digest it calculated itself. 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. Data Signature A Digest of the Data block encrypted using the Private Key of the Signer. To the original (usually larger) data block. Data Digest A relatively small block of data calculated by applying a special digest function Public Keys are usually distributed in the form of Certificates.

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.
