on limiting smart card constraints on UIMs Contractual

This report considers the use of smart cards as mobile personal security modules. The format of a smart card is described and the impact that this format has on both the way a smart card can be used as a security module and the limitations that the smart card imposes are discussed. The security threats to smart cards, from physical to technological and environmental, are considered along with the various measures that are or can be adopted to prevent them. Further sections consider: • how the performance limitations of smart cards for cryptographic purposes may in certain circumstances, be circumvented • the use of operating system commands for application implementation and how this may be improved by use of an interpreter concept along the lines of the Java Card API • the required security functionality of a UIM in the UMTS system.
