招生意向

在网络空间安全专业（网络与系统安全方向）招收博士、硕士研究生，将主要开展国际水准的移动安全与物联网安全方向研究。研究项目获得国家自然科学基金、山东省泰山学者工程、山东省自然科学基金、山东大学高层次人才学科建设经费、小米公益基金会等支持。研究成果发表于IEEE S&P、USENIX Security、ACM CCS、NDSS、ICSE、WWW等多个系统安全&软件工程领域顶级/知名国际会议。欢迎对于系统安全研究具有浓厚兴趣，具备良好编程动手能力及系统软硬件知识的同学报考。

课题组为科研表现优异的研究生提供多种形式的国内/海外学术交流访问机会，为优秀硕士生提供硕转博衔接培养机会，为优秀博士生提供赴海外顶级系统安全实验室访问机会（已出访学校包括：新加坡国立大学、乔治梅森大学、香港中文大学）。

有意报考同学请通过电子邮件同我取得联系（2025年秋季入学硕士研究生招生名额剩余：1），标明推免报考类型（专硕/学硕）。按照学院要求，不可在正式录取前确认学生，推免同学建议在【我院推免录取名单公示后】同我联系，考研同学建议在【通过我院研招复试后】同我联系。我院博士招生采用申请-考核制，一般在12月（来年4/5月可能有少量名额的第二批招生）开展招生工作，可随时联系，但预计在11月名额才会较为确定。

报考硕士研究生的同学需具备信息安全、计算机、软件工程等电子信息类本科专业背景，通过英语六级，请提供【简历】+【本科成绩单（含英语六级成绩）】，CTF等信息安全类竞赛科研经历为加分项。申请博士研究生的同学需具备计算机安全或相关领域（如软件工程、操作系统等）研究基础及论文发表经历，请提供【简历】+【论文代表作（即第一作者论文）】。如未提供有效材料，恕无法回复邮件。

再次强调一下，本组研究方向关注现实安全问题，为非理论性研究，学生需具备【软件安全基础、良好的编程与系统搭建能力】，以便开展科研。P.S., 本组的专业型硕士研究生（专硕）亦采用科研导向的培养模式，毕业标准参照学术型硕士研究生（学硕）。

P.S., 山东大学为中央网信办和教育部一流网络安全学院建设示范项目高校。网络空间安全学院位于山东大学青岛校区，地处青岛市“蓝色硅谷”核心区，依山傍海，空气清新，景色宜人，校园距离海边直线距离不足500米。

To 本院学生:

• 应已选修『软件安全』与『逆向工程』两门课程（体现一下你对软件与系统安全方向的兴趣）。

• 联系前请明确在本校继续读研的意愿和优先级（而非用学院保底）。

• 已保研至本组的本院学生会在大四阶段参与科研实践，以尽早获得科研产出。
