About Me

国防科技大学计算机学院副研究员，硕士生导师，长期从事公钥密码研究，研究成果发表于CRYPTO、ASIACRYPT、PKC、CT-RSA、IEEE TIFS、IEEE TDSC、IEEE TSC 等学术会议和期刊；担任中国密码学会青年工作委员会委员，以及ASIACRYPT、CT-RSA、ESORICS、ACM ASIACCS等国际学术会议程序委员会委员；入选第三届"中国科协青托工程"，获评2020年"ACM China SIGSAC新星奖"，2021年获得国家自然科学基金"优秀青年科学基金项目"资助。

I got the Ph.D. in cryptography from University of Wollongong, Australia in 2016. Before that, I received the B.Eng (2011) and M.Eng (2013) in computer science from National University of Defense Technology, China.
My major research interests include public-key cryptography, information security and network security. I am interested in designing provably secure cryptographic protocols against real-world attacks (e.g., typical attacks, leakage attacks and subversion attacks), and applying cryptographic techniques to protect data security and user privacy against the (possibly) untrusted cloud service and compromised computer network.
I was a visiting researcher at COSIC in KU Leuven, Belgium from 2019.03 to 2020.03. My host was Prof. Bart Preneel.
