Administrative signature 
Precursor to the
qualified signature(?).
Certificates(?) for administrative signatures are not issued anymore, but still remain valid until their expiry date (end of 2012 at the latest). An administrative signature is an
advanced signature(?) that is equivalent to a qualified signature in
e-government(?).
If you have an administrative signature and want to change to a qualified signature, you will need a new e-card:
- Online e-card order form (in the Reason field
enter
the following: Citizen card (change to a qualified certificate)
or
- call the e-card service line: 050 124 33 11
Adobe signature 
A worldwide standard for signing
PDFs. It was developed by the company
Adobe (creator of the
PDF format). Adobe signatures can be verified directly in
Adobe Reader. They are not compatible with
PDF-AS(?) signatures. In order to create a
qualified signature(?), a
plug-in is required.

Advanced signature 
Applet 
A software program that runs in a browser (Firefox, Internet Explorer, Safari, etc.)
Applets are written in the programming language
Java(?).
Asymmetric encryption [Public key encryption] 
A sophisticated encryption method in which a different key is used for encryption and decryption. One part of this key pair is open (
public key(?)), the other part is secret (
private key(?)). Well-known asymmetric encryption algorithms are
RSA(?) and
ECDSA(?).
Base64 
A coding system that uses 64 different characters (26 upper-case letters, 26 lower-case letters, 10 digits 0-9,
+
and
/
).
Base64 is widely used -
e.g. all e-mail attachments are coded in this form.

such as the A-
Trust citizen card environment,
trustDesk(?) and hotSign(?).
CRR number [Central Register of Residents number] 
A number assigned to you in the Central Register of Residents (
CRR). Every person registered in Austria can be uniquely identified by this number.
CRR numbers are 12 digits long,
e.g. 000247681888. They consist of random numbers and a checksum.
You can see your
CRR number on your proof of residency certificate (this replaces the old registration document starting Mar. 1, 2002):

e-card G2 [e-card 2nd Generation] 
All cards issued before December 2009. You can also check the top right corner (under the
SI
logo) - there will not be any braille text.
G2 e-cards contain two
ECDSA(?) key pairs.

e-card G3 [e-card 3rd Generation] 
e-government 
e-government (German: "e-Regierung") is a general description for the effort to simplify public administration processes using computers.
ECDSA 
A newer
asymmetrisc encryption algorithm(?) that is based on elliptic curves.
ECDSA is more advanced than
RSA(?) (
i.e., it produces shorter signature values), but is not yet as widely used. The abbreviation stands for
Elliptic Curve Digital Signature Algorithm
.
EGIZ 
The
e-Government Innovation Centre
(E-GIZ) is a shared initiative between the Federal Chancellery and the Technical University Graz. It is responsible for developing the
citizen card software(?) amongst other things.

Electronic signature [digital signature] 
The electronic version of a hand-written signature. The Austrian Electronic Signature Act recognises three levels of quality for electronic signatures:
- electronic signature (also referred to as the
simple electronic signature
for reasons of clarity)
- advanced electronic signature(?)
- qualified electronic signature(?)
FinanzOnline 
The Finance Office's Internet platform for taking care of tax matters online.

Hash value [fingerprint, message digest] 
A checksum number derived from the original text. It is used to check if the text is complete and whether or not it has been manipulated. Popular
hash algorithms are
MD5,
CRC and
SHA(?).
It comes from the English verb "
to hash", meaning to cut into small pieces. On restaurant menus, "
hash" is another name for ground beef.
hotSign 
Identity link 
An identity link is used to establish a connection between your
qualified certificate(?) and your
source PIN(?). Since you are only identified in the certificate by your name, mix-ups can occur if someone has the same name as you. On a technical level, the identity link is a file signed by the SourcePIN Register Authority in
XML(?) format. It is saved to the chip on your card during the
activation process(?).
Infobox 
Memory area on the e-card. The
identity link(?) is
e.g., saved in an infobox; as are mandates.
Infobox PIN 
With citizen cards on older debit cards (Maestro), access to the
Infobox(?) (where the
e.g. identity link(?) is saved) is protected with a
PIN(?). The infobox PIN is set to
0000
by default
IT Solution 
IT Solution has been developing software for digital signatures for different areas of application since 1998.

Mobile phone signature 
The mobile phone signature is a fully functional citizen card that you can activate on your mobile phone. The main advantage is that you do not need a
card reader(?) in order to use it. To activate your mobile phone as a citizen card, see
mobile phone activation.

Mocca 
Citizen card software(?) recommended by the Austrian Federal Chancellery (citizen card environment).
EGIZ(?) coordinates the development of the software. The software is free-of-charge; the source code is open (
Open Source). The name stands for
Modular Open Citizen Card Architecture
.

Non-qualified certificate 
A
certificate(?) that is not a
qualified certificate(?). The Electronic Signature Act (Sig
G) does not have a special term for this type of certificate. In many places, they are referred to as
simple certificates
or
advanced certificates
.
Official photo identification (Activation) 
These are the identification documents that are accepted at the registration sites:
- International Passport
- Austrian driver's license
- Austrian Identification Card
- Austrian Identity Card
- Apothekerausweis
- Behindertenpass
- Dolmetscherausweis
- eDA Dienstausweis Republik Österreich
- EDU-Card

Official signature 
This is the
electronic signature(?) used by the authorities that adheres to the
PDF-AS(?) standard. An official signature can be an
advanced(?) or a
qualified signature(?). An official signature consists of:
- The logo(?) of the signing authority
- Notification that the document was officially signed
- Notification that the signature was verified
Online CCE [CCE online] 
PC/SC Interface [PC/SC Standard] 
A standardised interface for
card readers(?) for accessing
chipcards(?). The name stands for
Personal Computer / Smart Card
.
PDF-AS 
A standard specified by
EGIZ(?) for signing
PDFs. The abbreviation
AS
originally stood for the German word
Amtssignatur(?)
(official signature), in reality however,
all citizen card users can create
PDF-AS signatures.
PDF-AS signatures are not compatible with
Adobe signatures(?).
PDF-AS signatures always contain a
signature block(?). With PDF-AS text signatures, this makes it possible to verify the signature on printed documents (however, this requires that the entire text be typed in).

PIN [PIN code] 
A password in the form of a combination of numbers that must be entered in order to carry out certain actions. The PIN is a security measure to prevent unauthorised access. The citizen card on the e-card is protected by a
signature PIN(?) and a
card PIN(?). The name stands for
Personal Identification Number
.
Private key 
The secret part of the key pair that is used in
asymmetric encryption(?). Information that is encrypted (signed) with the private key can only be decrypted again with the
public key(?).
Public key 
The public part of the key pair that is used in
asymmetric encryption(?). Information that is encrypted (signed) with the public key can only be decrypted again with the
private key(?).
Qualified certificate 
Qualified signature 
Revocation password 
This password allows you to deactivate the citizen card functionality (both
certificates(?) will be permanently revoked). The revocation password consists of 6 to 10 characters (letters and digits). You can choose the password upon
activation(?).
(Without your revocation password, you will not be able to revoke the citizen card, however, you will still be able to suspend it.)
Root certificate 
RSA 
One of the oldest
asymmetric encryption algorithms(?).
RSA is more widespread than the more modern
ECDSA(?), however it creates longer signature values. The abbreviation comes from the initials of the three developers
Ronald L. Rivest, Adi
Shamir und
Leonard Adleman.
RTR GmbH 
Sector specific personal identifier [ssPIN] 
A number derived from the
source PIN(?) which can be used by public authorities to identify a person (
e.g. j/NxdRQhp+tNyE9WhHdBSYuy3hA=). To calculate the sector specific personal identifer, a sector code (identifying the sector) from the respective area is used (along with the source PIN) (
e.g. UW
for environment (German: Umwelt) or
SA
for taxes (German: Steuern und Abgaben). This process ensures that one person is not able to be identified across different administrative areas. It is also not possible to recalculate the original source PIN from the sector specific personal identifier.
Security layer 
SHA 
The hash algorithm used with the citizen card. The abbreviation stands for Secure Hash Algorithm
.
Signature card 
Signature password [Signature password] 
This password protects access to the citizen card functionality on mobile phones. Basically, it's a PIN code for your mobile phone. The signature password consists of 6 to 20 characters (letters and digits). You can choose the password upon
activation(?).
Signature PIN 
The signature PIN allows you to create a
qualified signature(?). For the e-card, it is a 6 to 12 digit number. You can choose your PIN number upon
activation(?).
Signature visualisation 
The relevant components of an
electronic signature(?) saved in table form as specified in
PDF-AS(?). The main parts in the signature visualisation include:
- The signature value (=signed hash(?))
- The name of the signer
- Date and time
- The number of the underlying certificate(?)
- Info about where the signature can be verified
For
official signatures(?) it also contains:
- The logo(?) of the signing authority
- Notification that the document was officially signed
Example:

Social insurance number [SI number] 
This ten digit number is your customer number for your social insurance provider. The last six numbers are usually (but not always) your date of birth (
e.g., 050670
for June 5, 1970).
Source PIN 
A number derived from your
CRR number(?) (
e.g. Qq03dPrgcHsx3G0lKSH6SQ==). It builds the base for the
identity link(?). The source PIN is created using
Triple-DES(?) encryption. It is impossible to calculate the original
CRR number from the source PIN.
SourcePIN Register Authority 
Stork 
An
EU initiative to link all the different "citizen card" (e
ID’s) from different European countries together. The abbreviation stands for
Secure identity across borders linked
.
Stork Website 
Supplementary Register 
A supplementary register to the Central Register of Residents (CRR) that allows persons not registered in Austria to obtain a citizen card.
Background info: The
identity link(?) of the citizen card is based on the
source PIN(?), which is derived from the
CRR number(?). Anyone who is not registered in Austria will not be listed in the Central Register of Residents and will therefore not have a
CRR number.
- The Supplementary Register for Natural Persons contains private persons.
- The Supplementary Register for Others contains legal persons that are not entered in the Commercial Register.
The Supplementary Register is managed by the
SourcePIN Register Authority(?).
Symmetric encryption 
An encryption method that uses the same key to encrypt as well as decrypt data. (as opposed to
asymmetric encryption(?)). The most widely-used symmetric encryption algorithms are
IDEA,
AES and
DES(?).
TAN 
The second part of authentication for the citizen card on your mobile phone. After you have logged in with your
signature password(?), you receive a
SMS with your TAN code. It consists of 6 characters (letters and digits) and is valid for five minutes. TAN stands for
transaction number
.
Triple DES [3DES] 
A
symmetric encryption algorithm(?). The block size is 64 Bit,
i.e. the length of the information to be encrypted must be a multiple of 64 Bits. The
triple
designation means, in essence, that the
DES encryption process is repeated three times. The abbreviation
DES
stands for
Data Encryption Standard
.
trustDesk 
Verifying signatures on printed documents 
Using the
PDF-AS(?) standard, it is possible to verify text signatures on printed documents. In order to do this, the
entire text and the signature value from the
signature block(?) has to be typed in. Invisible characters (multiple spaces, paragraph tags, TAB markers, etc.) are automatically ignored when verifying the signature. The
PDF-AS(?) standard contains comprehensive "normalisation measures" to deal with them.

XML 
A standardised file format used to exchange information. For example, for a person named Susanne Muster, born Jan. 1, 1950, the following would appear in her
identity link(?):
<pr:Name>
<pr:GivenName>Susanne</pr:GivenName>
<pr:FamilyName primary="undefined">Muster</pr:FamilyName>
</pr:Name>
<pr:DateOfBirth>1950-01-01</pr:DateOfBirth>
