In the context of smart cards, an application protocol data unit (APDU) is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4 Organization, security and commands for interchange. [1]
The CCID (Chip Card Interface Device) is a USB protocol that allows a smart card to be interfaced to a computer using a card reader which has a standard USB interface. This allows the smart card to be used as a security token for authentication and data encryption such as Bitlocker .
Smart card management systems connect smart cards to other systems. Which systems the smart card management system must connect to depends on the use case for the smart cards. Typical systems to connect to include: Connected smart card reader [4] Unconnected smart card reader; Card printer; User directory; Certificate authority [5]
Access to smart cards is provided through an enhanced version of the OpenCard Framework. Drivers are included for most ISO/IEC 7816-4 compliant smart cards, PC/SC and CT-API card readers. The platform also provides cryptographic support through the Java Cryptography Extension (JCE) with the Bouncy Castle Crypto API.
A Secure Access Module (SAM), also known as a Secure Application Module, is a piece of cryptographic hardware typically used by smart card card readers to perform mutual key authentication. [ 1 ] [ 2 ] [ 3 ] SAMs can be used to manage access in a variety of contexts, such as public transport fare collection and point of sale devices.
