| Secret Key |
The key used in a symmetric cryptographic algorithm, where
the same key is used for encryption and decryption |
|
| Secure Application Module (SAM) |
A physical module (or a logical functionality in the CAD) intended
to contain algorithm(s), related keys, security procedures and
information to protect an application in such a way that unauthorized
access is not possible. In order to achieve this, the module must
be physically and logically protected. |
ISO |
| Secure Audit Trail |
The historic data and information which are available for examination
in order to prove the correctness and integrity with which the
agreed security procedures have been followed and which allows
breaches in security to be detected. |
ISO |
| Secure Electronic Transaction (SET) |
A MasterCard/Visa backed standard to allow safe Internet trading
via encryption certification of all parties involved in a transaction. |
|
| Secure Messaging |
Transfer of authenticated and/or enciphered data between two
entities. |
|
| Secure Socket Layer (SSL) |
A protocol designed by Netscape Communications to enable encrypted,
authenticated communications across the Internet. SSL is used
mostly in communications between web browsers and web servers. |
|
| Security Features |
Measures taken to achieve a reasonable freedom from accidental,
criminal, fraudulent, and vandalizing actions while maintaining
sensitivity to unexpected attacks or system failures that cannot
be distinguished from attacks. |
|
| Self-insurance |
A type of group insurance where the group uses internal means
and assumes the financial risks involved in providing healthcare
protection. This takes the place of obtaining coverage from commercial
health insurance carriers. |
|
| Settlement |
Transfer of funds to complete one or more transactions. |
|
| Settlement Conversion Rate |
The rate applied to convert a transaction value from the currency
of denomination into the relevant settlement currency. |
|
| Signature Dynamics |
A PIV technique based on measurements of pen position and pressure
as a function of time during signature writing. |
|
| Signature Panel |
A panel on a card on which the cardholder’s signature is displayed. |
|
| Single-application card |
An operating system that supports a single application. |
|
| SIM card |
An integrated circuit chip residing on a piece of plastic,
which is smaller than an ISO 7816 card. SIM cards are used most
frequently in cell phones. |
|
| Skimming |
Electronically copying the card data from one card to another. |
|
| Smart Card |
An integrated circuit card with a microprocessor, i.e. capable
of calculation. |
|
| SPOM |
Self-Programmable One Chip Microcomputer. |
|
| Standard |
A voluntary agreement to a uniform and consistent methodology
and/or specification to achieve a common action or result. |
|
| Standardized Processes and Protocols |
Guidelines for common data requirements, utilization control
requirements, and documentation requirements across all payers. |
|
| Standing Order |
A pre authorized payment in which a customer instructs his/her
bank to pay fixed sums at regular intervals or on defined dates. |
|
| Static Authentication |
An off-line cryptographic process that verifies plaintext data,
stored in the ICC, against cryptographic data also stored in the
ICC. |
|
| Static Random Access Memory |
Random access memory that does not need to be refreshed on
each memory cycle. |
|
| Storage |
An electronic and/or mechanical magnetic device that holds
information for subsequent use or retrieval. |
|
| Store and Forward |
A mode of message handling in which on-line and off-line operation
are mixed. Sore and forward operation occurs when a message cannot
be transmitted on-line immediately to its destination but is retained
for transmission when the destination system comes on-line again. |
|
| Store Card |
A financial transaction card associated with a particular retailer
or group of retail stores, which can be used only for purchases
from that retailer or at the stores concerned. |
|
| Stored Value Card |
A card that contains a value that is decremented when used. |
|
| Subscriber Identity |
A device used in the GSM application to link a phone number
to a specific person instead of linking the number to a specific
phone set. |
|
| Super Smart Card |
A card shaped device that has an on board keypad, LCDs, and
batteries, as well as one or more integrated circuit chips capable
of storing and processing data. |
|
| SWIFT |
Society for World Wide Interbank Financial Telecommunication.
Communication mechanism owned by more than 1,000 banks around the
world and used to transmit funds, transfer instructions and administrative
messages. |
|
| Swipe Reader |
A magnetic stripe reader in which the magnetic stripe is read
by passing the card manually right through the reader past the
magnetic heads. |
|
| Switching |
Establishment and dis-establishment of connections in a communications
network. |
|
| Symmetric Key Cryptography |

the boundaries between successive individual bits. |
|
| Synchronous Password Generation |
A method of generating a unique one time password for computer
users based on time or transaction synchronization between a host
and a device at the point of transmission. |
|
| Symmetric Key Cryptography |
Cryptographic processes in which encryption and decryption
rely on the same secret key. |
|
| System Software |
Programs that control the internal operation of a computer.
They consist of operating system and packages to improve the efficiency
and capabilities of the computer, such as communications control
programs and data base management programs. Applications software
runs under systems software. |
