Welcome to CryptoPlus!

We are a group of people passionate about cryptography and its rich connections with various fields, including computational complexity, algorithm design, quantum computing, system/network security, and more. Modern cryptography serves as a fascinating nexus between these areas, offering a dynamic space for exploration.

At CryptoPlus, we start our journey in the "hometown" of cryptography, but our odyssey is not solely about advancing the field — we view cryptography not only as a discipline but also as a playground to engage with a diverse set of technical tools from mathematics, computer science, and even physics. These tools, while varied, share a common characteristic: they exemplify scientific curiosity and creativity. It is this characteristic that motivates our passion and fosters the intellectually stimulating environment in our lab. We aspire to contribute our own share to the ongoing development of creative ideas, producing research that not only advances cryptography but also extends into other areas, initially through the lens of cryptographic thinking but eventually beyond — a vision that is reflected in our name: CryptoPlus!
