CCID -  Circuit Card Interface Device. A subset of the USB specification that is the standard for USB based smartcard readers.
- Synonyms: communication port, comm. port, serial port
CD -  Coupling device or coupler. A device able to communicate with an ICC. This is what everybody calls a smartcard reader. Technically speaking it could be seen as a gateway between the computer and the card.
- Synonyms: coupler, smartcard reader, reader
Certificate -  A file, digitally signed by a Certification Authority. There are many different types of certificates (the most common being X 509 V3).
- Synonyms: NFCIP-2
Certification Authority -  The organization that issues certificates and takes liability associated with the validity of the holder's identity. Often financial and institutional organizations.
- Synonyms: CA
Checksum -  A count of the number of bits in a transmission unit so that the recipient can make sure the correct number of bits arrived and that the message is intact.
- Synonyms: CA
CMOS -  Complementary-symetry/metal-oxide semiconductor. Two important characteristics of CMOS devices are high noise immunity and low static power supply drain. Significant power is only drawn when its transistors are switching between on and off states; consequently, CMOS devices do not produce as much heat as other forms of logic such as TTL. CMOS also allows a high density of logic functions on a chip.
- Synonyms: CA
Compiler -  A compiler is a computer program (or set of programs) that translates text written in a computer language (the source language) into another computer language (the target language).
- Synonyms: CA
Confidentiality -  Guarantee that a message will be legible to no-one other than the intended recipient. Confidentiality is an essential part of cryptography systems.
- Synonyms: CA
CPU -  A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets instructions and processes data contained in computer programs.
- Synonyms: CA
CRC -  Cyclic Redundancy Check. A popular mean of ensuring transmissions have not been garbled.
- Synonyms: CA
CryptoAPI -  A Microsoft API that offers system-level access to common cryptographic functions in Windows systems.
- Synonyms: CA
Cryptography -  The science of ensuring that messages are secure. Cryptographic systems are based on the concepts of authentication, integrity, confidentiality and non-repudiation.
- Synonyms: CA
