SGX STEP建立流程

Question

我正在尝试按照1

中的说明实施sgx Foreshadow漏洞。

但出现以下错误：

import ast
codetoanalyze=ast.parse(open("/path/to/script_to_analyse.py",'r').read())

if next((x for x in codetoanalyze.body[1].body if x.name == "run"), None) == None :
     raise ValidationError( _('Package error : module must contain a "run" method'), code='compilation_error', )

if next((x for x in codetoanalyze.body[1].body if x.name == "rollback"), None) == None :
     raise ValidationError( _('Package error : module must contain a "rollback" method'), code='compilation_error', )

如何实现此漏洞？
