It reads instructions and data from memory and performs the arithmetic and logic operations defined by the instruction. A complete computer system includes CPU, main memory, clock circuits and input and out-put devices. Cryptographic Coprocessor Special hardware blocks for efficient computations of cryptographic calculations, such as modular arithmetic and large integer calculations. These circuits are added to a standard processor core and therefore are called coprocessors. Mobile RFID memory consisting of memory, a transmitter and a receiver in a plastic housing unit or plastic card.
Some transponders have additional functions to secure, protect or select access to the transponder.
A symmetric encryption algorithm. First ever implemented crypto algorithm on a smart card and introduced by Philips in 1985. Digital Signature A cryptographic protocol that ensures the authenticity as well as the integrity of digital data. A digital signature typically is realized by encrypting the hash value of the data to be protected with the private key. A cryptographic algorithm approved by the U.S. government for use in creating digital signatures.
