密码是关系国家根本利益的战略资源,是网络空间安全的核心技术和基础支撑。密码学实验室目前有全职科研人员 5 人,实验室负责人为赵运磊特聘教授、国家级人才称号获得者,国家重大项目首席科学家。实验室研究方向为:后量子密码、区块链、密码协议、面向新应用新业态(5G、智能群组、物联网、云计算)的新型密码技术及应用、密码工程及芯片、量子计算。在Journal_of_Cryptology,EUROCRYPT,ACMCCS, ICALP,TCC,PKC,ESORICS,CT-RSA, IEEE-TIT, IEEE-TIFS,IEEE-TDSC等发表论文100余篇,多项成果作为单独章节写入密码学国际著名教材,多项研究成果作为标准得到大规模应用,获得和申请国际和国家发明专利40余项。
实验室坚持面向国际前沿的自由探索与对接国家重大需求的目标导向“两条腿”走路,注重理论与实践相结合,注重产学研融合发展和成果转化应用,与密码头部企业建有校企联合实验室和成果转化和示范应用平台。对学生注重强基础、重应用、成体系的培养。实验室对学生支持条件优越,实验室学生参照互联网大厂的实习生待遇进行资助,使学生安心科研深造。培养的学生曾获得全国密码技术竞赛特等奖、ACNS最佳学生论文奖等荣誉,毕业学生到麻省理工、康奈尔、普渡等国际著名大学深造。
