microprocesador que realiza operaciones sobre datos almacenados internamente o

(I) A credit-card sized
device containing one or more integrated circuit chips that perform the
functions of a computer's central processor, memory, and input/output
interface. (See: PC card, smart token.)
Usage: Sometimes this term
is used rather strictly to mean a card that closely conforms to the dimensions
and appearance of the kind of plastic credit card issued by banks and
merchants. At other times, the term is used loosely to include cards that are
larger than credit cards, especially cards that are thicker, such as PC cards.
[RFC4949:2007]
(I) A device that conforms
to the definition of "smart card" except that rather than having the
standard dimensions of a credit card, the token is packaged in some other form,
such as a military dog tag or a door key. (See: smart card, cryptographic token.)
[RFC4949:2007]
On définit la carte à
puce de manière générale comme "un ordinateur personnel de la taille d'une
carte de crédit" (Simon Davies). Il s'agit d'une carte disposant de moyens
intelligents dont le but est de mettre en oeuvre des calculs cryptographiques
permettant d'assurer les services de sécurité suivants: authentification,
confidentialité, intégrité et preuve.
