Precise positioning method of intelligent-card platform joint-attack

The invention discloses a precise positioning method of an intelligent-card platform joint-attack, and belongs to the technical field of intelligent cards. The method includes: constructing an attack-used source program; finding a statement, where an attack point is located, on the basis of the source program; and adding loop body code and adjacent positioning code before the statement where the attack point is located, wherein the loop body code is multiple loops of the adjacent positioning code, and the adjacent positioning code is multiple loops of single code. Through using the framework,a special test application is generated, and can be used for positioning in a joint-attack process on an intelligent-card platform, and the problem that the attack point cannot be precisely located inthe joint attack is solved. 本发明公开种智能卡平台联合攻击的精准定位方法，属于智能卡技术领域。该方法包括：构建攻击用源程序；在所述源程序的基础上，找到攻击点所在的语句；在攻击点所在语句的前面，添加循环体代码和相邻定位代码。循环体代码为相邻定位代码的多次循环。相邻定位代码为单代码的多次循环。通过使用该框架，生成特殊的测试应用，可用于对智能卡平台进行联合攻击过程中的定位，解决了联合攻击中无法精确定位攻击点的问题。
