JCSI

JCSI is a prototype tool for the analysis and visualisation of Java Card CAP files. The analysis method implemented in the tool is based on the theory of abstract interpretation and a multi-level security policy assignment. Actual values of variables are abstracted into security levels, and bytecode instructions are executed over an abstract domain. The tool can be used for discovering security issues due to explicit or implicit information flows and for checking security properties of Java Card applications downloaded from untrusted sources.
