SYSTEM AND METHOD FOR STATIC DETECTION AND CATEGORIZATION OF INFORMATION-FLOW DOWNGRADERS |
| 摘要 |
A system and method for static detection and categorization of information-flow downgraders includes transforming a program stored in a memory device by statically analyzing program variables to yield a single assignment to each variable in an instruction set. The instruction set is translated to production rules with string operations. A context-free grammar is generated from the production rules to identify a finite set of strings. An information-flow downgrader function is identified by checking the finite set of strings against one or more function specifications. |

1. A method for static detection and categorization of information-flow downgraders, comprising:
transforming a program stored in a memory device by statically analyzing program variables to yield a single assignment for each variable in an instruction set; translating the instruction set to production rules with string operations to identify a finite set of strings; generating a context-free grammar from the production rules; and identifying an information-flow downgrader function by checking the finite set of strings against one or more function specifications. |
