Two main motivation for using PKI technologies are: en:esya:aaa Fri, 26 Jul 2013 12:18:57 +0000 https://yazilim.kamusm.gov.tr/esya-api/doku.php?id=en:esya:aaa:akilli-kart&rev=1375077976&do=diff Smartcards Smartcards are the most popular devices for storing digital certificates and private keys in a secure way. They have programmable processors and secure memory and they are extremely solid and portable. They are used in systems where information security, identity confidentiality and mobility are the main concerns. Smartcard that have cryptographic processors have the following capabilities: en:esya:aaa Mon, 29 Jul 2013 06:06:16 +0000 https://yazilim.kamusm.gov.tr/esya-api/doku.php?id=en:esya:aaa:cisdup&rev=1377600566&do=diff Online Certificate Status Protocol (OCSP) Since CRLs are issued periodically, they do not provide a real time information about the status of certificates. In cases like financial operations where real time validation is required, using CRLs as the source of revocation information is not considered to be secure enough and unacceptable. As a remedy, Online Certificate Status Protocol (OCSP) is used. en:esya:aaa Tue, 27 Aug 2013 10:49:26 +0000 https://yazilim.kamusm.gov.tr/esya-api/doku.php?id=en:esya:aaa:sertifika-makam%C4%B1&rev=1378991849&do=diff Certificate Authority Certificate Authorities (CA) are the central authority who are responsible gor the creation and management of certificates. CA consists of software and hardware components as welle as the people who operate the system. A CA differs from another in its name and key pair (public and private). en:esya:aaa Thu, 12 Sep 2013 13:17:29 +0000 https://yazilim.kamusm.gov.tr/esya-api/doku.php?id=en:esya:aaa:sertifika&rev=1378992730&do=diff Digital Certificates In asymmetric cryptography a key pair , including private and public keys, is defined for each subject. The public key can be accessible by everyone who wants to communicate with the owner of that key. In order to make public key easily accessible by everyone, it is published within the corresponding certificate en:esya:aaa Thu, 12 Sep 2013 13:32:10 +0000 https://yazilim.kamusm.gov.tr/esya-api/doku.php?id=en:esya:aaa:sil&rev=1378991741&do=diff Certificate Revocation List (CRL) Once a certificate is published it is impossible to make it totally inaccessible due to its revocation. For this reasons CAs publish Certificate Revocation Lists(CRL) in order to announce everyone that the certificates in the CRL are revoked. en:esya:aaa Thu, 12 Sep 2013 13:15:41 +0000
