Definitions and abbreviations
3DES / TDES Triple DES algorithm
AES Advanced Encryption Standard algorithm as defined in FIPS PUB 197
APDU Application Protocol Data Unit as defined in ISO7816-3
Authentication An identification or entity authentication technique assures one party (the verifier), through acquisi-
tion of corroborative evidence, of both the identity of a second party involved, and that the second
(the claimant) was active at the time the evidence was created or acquired. (From Handbook of
Applied Cryptography)
ASSP Application Specific Standard Product
CBC Cipher Block Chaining method applied to block ciphers
CFB Cipher Feedback Register chaining method applied to block ciphers
CMAC Cipher-based Message Authentication Code
CPU Central Processing Unit
Cryptographic key A bit string used as a secret parameter by a cryptographic algorithm. To prevent a key from being
guessed, keys need to be generated truly randomly and contain sufficient entropy.
DES Data Encryption Standard algorithm as defined in FIPS PUB 46-3
Device Any CPU with master or slave capability
ECB Electronic Code Book chaining method applied to block ciphers
EEPROM Electrically Erasable Programmable Read-Only Memory
FAT File Allocation Table - file system from Microsoft ®
FIPS Federal Information Processing Standards
FIPS-approved An algorithm or technique that is specified or adopted in FIPS
HMAC Hash-based Message Authentication Code as defined in FIPS PUB 198
Host Entity that communicates (directly or not) with the device
HOTP HMAC-based One Time Password algorithm as defined in RFC 4226
ISO7816 Smart Card interface
MAC Message Authentication Code - A bit string of fixed length, computed by a MAC generation algo-
rithm, that is used to establish the authenticity and, hence, the integrity of a message.
Master The device that initiates and terminates a transmission. The Master also generates the clock for syn-
chronous interface.

NVM Non Volatile Memory (EEPROM, flash, …)
OFB Output Feedback Register chaining method applied to block ciphers
SCP Secure Channel Protocol as defined by GlobalPlatform
SHA Secure Hash Algorithm
