I am currently pursuing my Ph.D. in Cryptography at Wuhan University (WHU), supervised by Huanguo Zhang.
I am also a CSC Joint Ph.D. student at the University of Wollongong (UOW), hosted by Willy Susilo and studying with the iC$^2$.

Before (Sep 2016 - Jun 2020), I completed my B.Sc. in Mathematics, also at Wuhan University.

My research interests are about cryptography and cyber security, to be more specific:

• Recently, my passion lies in analyzing and designing zero-knowledge protocols and signature schemes derived from them, mainly based on linear algebra assumptions that conjectured quantum-resistant (e.g., Lattice, Multivariate, and Code).
• In the long term, I hope using technologies to establish trust among individuals at almost zero cost, which I consider to be the most subtle and elegant aspect of cryptography.

🧰 Misc

Serendipity

My name starts with “jiami” (Chinese for “encrypt”), and ends with “mingwen” (Chinese for “plaintext”).
I remove “ng” from it to obtain “miwen” (Chinese for “ciphertext”) for several usernames of mine, e.g., wechat, twitter, and github, as I believe it is more suitable for spreading over the public channel :)

Some useful links

• My bilibili space, including several talks/courses I am or was interested in.
• IACR ePrint Archive, a mysterious website suggested visiting every day.
• The Lattice Club, including so many resources about Lattice-based Cryptography.
• Post-Quantum Signatures Zoo, including an overview of Post-Quantum Signatures.
• Kai-Min Chung’s Homepage, including high-quality cryptography courses in Chinese.
• Journal of WoCrypt, a very serious fake journal, whose outcomes include “安全归约导论”, “数字签名密史” and its slides. Here are my always-unfinished notes for the former and xmind for the latter, which I hope are salutes to Prof. Fuchun.
