Java on Smart Cards: Programming and Security

Smart cards are playing an increasingly important role in areas such as ban- 1 king,electroniccommerce,andtelecommunications. TheJavaCard language hasbeenproposedasahigh-levellanguageforprogrammingmulti-application smartcards. Theuseofahigh-levellanguagecanfacilitatethedevelopmentand veri?cation of software for smart cards. The modest code size and the imp- tanceoftheapplicationareasimpliesthatitisbothpossibleanddesirableto developandapplyformalmethodsintheconstructionofsafeandsecureJava Cardsoftware.
