Profile

I'm a Network Security Researcher.
My dream is to make the Internet more trustworthy and secure!


About me

I am a Postdoc Research Associate at Purdue University. I received a Ph.D from Network Convergence and Security Laboratory at Seoul National University. I like to design cryptographic protocols appropriate to diverse networks. Currently, I am interested in Transport Layer Security (TLS), Public Key Infrastructure (PKI), and Trusted Execution Environment (TEE) so that I will contribute to making the Internet more trustworthy and secure.
