DES

by 15/09/2014

Data Encryption Standard. The most widely used secret key encryption algorithm (orginally developed by IBM in 1977). A strengthened version of DES called triple DES (or 3DES) is commonly used in bank cards.

Definitioner

Secret Key

A cryptographic system that uses a single key for encrypting and signing data.

Key

A value that is used with a cryptographic algorithm to encrypt (or sign) data. The longer the key, the more secure the encryption.

3DES (Interoperability)

The ability of products manufactured by different companies to operate correctly with one another.

Triple DES (Interoperability)

The ability of products manufactured by different companies to operate correctly with one another.

3DES (Integrity)

Guarantee that a data (or code) has not been modified in transit. Integrity is an essential role of cryptography systems.

Triple DES (Integrity)

Guarantee that a data (or code) has not been modified in transit. Integrity is an essential role of cryptography systems.

3DES (Hash)

A crytographic functions that computes a fixed-size digest of any message, so the recipient can make sure the message has not been altered.

Triple DES (Hash)

A crytographic functions that computes a fixed-size digest of any message, so the recipient can make sure the message has not been altered.

3DES (Firmware)

Low-level software that is similar to hardware features. This software operates by exchanging commands directly with an external device or with a specific software loaded in the product.

Triple DES (Firmware)

Low-level software that is similar to hardware features. This software operates by exchanging commands directly with an external device or with a specific software loaded in the product.

Encryption

A cryptographic procedure whereby a legible message is encrypted and made illegible to all but the holder of the appropriate cryptographic key.

3DES (Encryption)

A cryptographic procedure whereby a legible message is encrypted and made illegible to all but the holder of the appropriate cryptographic key.

Triple DES (Encryption)

A cryptographic procedure whereby a legible message is encrypted and made illegible to all but the holder of the appropriate cryptographic key.

3DES (EMV)

Europay - Mastercard - Visa. The specifications and the certification process dedicated to the smartcards (and readers) used in banking applications.

3DES (EEPROM)

Electrically Erasable Programmable Read-Only Memory. Special non-volatile memory whose content can be erased and new data can be reloaded electrically. In smart cards EEPROM is typically used for application data and for certain filtered functions.

Triple DES (EEPROM)

3DES (Digital Signature)

An electronic signature created using a public-key algorithm. A digital signature can be used by the recipient to authenticate the identity of the sender and to ensure the integrity of the message.

Triple DES (Digital Signature)

An electronic signature created using a public-key algorithm. A digital signature can be used by the recipient to authenticate the identity of the sender and to ensure the integrity of the message.
