Tutorial Smart Command Library

Smart Card Command LibraryCS497 Project PresentationGuide: Dr. Rajat MoonaHitesh KhandelwalDepartment of Computer Science, IIT Kanpur Smart cards Smart cards are electronic card Dedicated processor and memory on a chip So data can be stored and compuation can be made Hence needs an Operation system too. The OS provides: A standard way of interchanging information An interpretation of the commands and data. Security mechanisms Optionally may have Crypto-coprocessors (implementing 3DES, AES, RSA, etc on chip) Cards must interface to a computer or terminal through a standard card reader SCOSTA Standard Based on ISO 7816-4, -8, and -9 Removes ambiguities in ISO 7816 Has support for symmetric key cryptography (3DES algorithm) and internal and external authentication. Encryption/decryption and crypto checksum computation and verification using 3DES are also supported. Command library Need a middleware to absract the interchange of information and performing crypt operations. Removing replication of code in different smart card based application Increasing structuring, modularity and modifiability of applications Reduce the time and cost of developing smart card based applications To promote a standard specification (compliant with SCOSTA, ISO 7816) Overview Compliant with the ISO 7816 and SCOSTA standards Provides easy-to-use wrapper functions which facilitates easy and quick way of performing a sequence of ...
