Protocol for exchange of messages between applications embedded in a multi-function smart card, uses transmission of calls from master application to cause operating system to load and execute slave application

摘要

The message protocol operates between applications on a smart card. A call request holding input/output information for the slave is transmitted (1000) from the master application to the card operating system. The master is deactivated and the slave (1001) activated and transmitted (1002) to the operating system, which supervises execution (1003) of the slave, returning results to the master.
