Original name record: 上海安般信息科技有限公司

Browse source applicant names and unchanged name fields from imported patent records.

These are name-based results, not verified legal entities. Identical names may refer to different people or organizations; aliases and historical names are not merged.

This page matches the complete original name field. It may contain multiple applicants or another recorded party role. Name boundaries and legal identities have not been verified; punctuation is preserved, not split.

Patent counts refer to distinct records held by this site, not an applicant’s complete portfolio. A joint name field is not a single company.

Verified corpus date coverage and last import time are not currently available. Publication dates on patent records are not import dates. Cached directory results may lag behind new imports.

一种基于Intel-PT和Syzkaller的灰盒模糊测试方法及系统

本发明提供一种基于Intel‑PT和Syzkaller的灰盒模糊测试方法及系统,方法包括:第一模糊测试引擎开启测试循环,不断测试并向管理器同步测试进展;管理器响应第一模糊测试引擎的poll请求向第一模糊测试引擎发送第二模糊测试引擎发现的新用例,第一模糊测试引擎的有效队列得到更新,开始生成新的用例并测试;第一模糊测试引擎将新的用例发送给执行器,执行器准备执行测试;执行器在执行测试前识别内核地址范围,收集新的用例的静态存储区,通过超级调用申请开启PT追踪功能;拦截控制寄存器设置请求,获取控制寄存器的值,并将控制寄存器的值赋值给超级调用的参数,控制寄存器的值为追踪系统的页表基地址;处理超级调用设置追踪的内核地址范围,设置页表基地址,开启PT追踪;执行器开始解析和执行输入用例,实时调用注册解析函数完成解析,填充到静态存储区中;经过执行器多轮系统调用的执行,将更新的覆盖信息同步至第一模糊测试引擎。本发明提供的基于Intel‑PT和Syzkaller的灰盒模糊测试方法及系统,能够用于闭源版本linux系统二进制灰盒模糊测试,形成有效的反馈信息闭环。
