11 The @emph{Authority Revocation List} is technical identical to a
12 @acronym{CRL} but used for @acronym{CA}s and not for end user
16 Verification model for X.509 which uses the creation date of a
17 signature as the date the validation starts and in turn checks that each
18 certificate has been issued within the time frame, the issuing
19 certificate was valid. This allows the verification of signatures after
20 the CA's certificate expired. The validation test also required an
21 online check of the certificate status. The chain model is required by
22 the German signature law. See also @emph{Shell model}.
25 The @emph{Cryptographic Message Standard} describes a message
26 format for encryption and digital signing. It is closely related to the
27 X.509 certificate format. @acronym{CMS} was formerly known under the
28 name @code{PKCS#7} and is described by @code{RFC3369}.
31 The @emph{Certificate Revocation List} is a list containing
32 certificates revoked by the issuer.
35 The @emph{Certificate Signing Request} is a message send to a CA to
36 ask them to issue a new certificate. The data format of such a signing
37 request is called PCKS#10.
40 A data format used to build a PKI and to exchange encrypted or
41 signed messages. In contrast to X.509, OpenPGP also includes the
42 message format but does not explicitly demand a specific PKI. However
43 any kind of PKI may be build upon the OpenPGP protocol.
46 This term is used by GnuPG to describe a 20 byte hash value used
47 to identify a certain key without referencing to a concrete protocol.
48 It is used internally to access a private key. Usually it is shown and
49 entered as a 40 character hexadecimal formatted string.
52 The @emph{Online Certificate Status Protocol} is used as an
53 alternative to a @acronym{CRL}. It is described in @code{RFC 2560}.
56 The @emph{Personal Security Environment} describes a database to
57 store private keys. This is either a smartcard or a collection of files
58 on a disk; the latter is often called a Soft-PSE.
62 The standard model for validation of certificates under X.509. At the
63 time of the verification all certificates must be valid and not expired.
64 See also @emph{Chain model}.
68 Description of a PKI used with CMS. It is for example
69 defined by @code{RFC3280}.
