Beyond Cryptography Papers: Exploring Real-World Impact

How did your journey evolve across different countries, universities, or research cultures?

It has profoundly shaped me, both personally and professionally. People often say that a person changes when they begin speaking a different language; I believe the same principle applies when one moves across cultures and environments.

Relocating to a new place is never only about work. It is also about meeting people, building relationships, and gradually becoming part of a different social and cultural environment. As one becomes more integrated into that environment, one inevitably absorbs aspects of its values, habits, and worldview. Over time, these experiences begin to influence not only how one works, but also how one thinks, communicates, and approaches life more broadly.

Living and working across different regions has taught me distinct lessons from each cultural context. In East Asian countries such as Vietnam and Japan, I developed a strong appreciation for collective respect, social harmony, and a deep sense of responsibility toward the broader community. These environments emphasized discipline in social conduct, attentiveness to others, and the importance of acting with consideration for the group rather than solely for the individual.

In Europe, I was exposed more strongly to values of creativity, intellectual independence, and innovation. I learned to think more critically, challenge assumptions more openly, and approach problems with greater originality and flexibility.

In Germany, I developed a deeper respect for discipline, structure, and precision in work. The professional culture reinforced the importance of reliability, organization, and maintaining high standards of execution.

In the United States, I experienced a markedly faster-paced, more ambitious work culture. It taught me the value of speed, decisiveness, and comfort with risk. I learned to be more action-oriented, to embrace uncertainty, and to pursue ideas with greater boldness and ambition.

Taken together, these experiences have significantly transformed my character. They have shaped how I think, how I work, and how I relate to others. Each place contributed something distinct, and collectively they made me more adaptable, open-minded, and intentional in both my personal and professional life.

 

When did the idea first emerge that you didn’t just want to do research, but also build a company?

As our work lies in applied cryptography, we believe its value should extend beyond theoretical contributions. While rigorous foundations remain essential, we do not wish for our research to remain solely on paper; rather, we aim to make a tangible impact in everyday life. This objective is particularly important given the alarming rise in online fraud, phishing, and cyberattacks over the past few years. The scale and consequences of such incidents are severe. Many individuals have suffered significant financial losses, in some cases losing their life savings, while numerous families have faced profound personal and economic hardship.

Because our research focuses on strengthening the security of online accounts and improving the protection of personal data in digital environments, we view this work as a way to contribute our small effort to society. By developing practical and deployable solutions, we hope to make digital systems safer for ordinary users and, even in a modest way, help reduce the harm caused by increasingly pervasive online threats.

 

Was there a specific turning point or situation that triggered this decision?

No, there was no single defining turning point that prompted this decision. Rather, it emerged from a gradual, sustained process of reflection, shaped over time by continued experience, observation, and growing awareness of the practical importance of our work. 

 

What has particularly shaped you—or perhaps challenged you—about working in international teams?

Nothing in particular comes to mind beyond the importance of respecting other cultures. There are often cultural norms, customs, or sensitivities that may not be immediately apparent, and something considered entirely acceptable in one culture may be perceived differently in another. Being mindful of such differences is important in order to interact respectfully and avoid unintended misunderstandings. At the same time, learning about different cultures is both enjoyable and enriching, offering valuable opportunities to gain new perspectives and broaden one’s understanding. 

"The program offers a uniquely supportive environment that significantly reduces constraints at the early stage. It creates a structured 'safe space' where participants can explore and validate their ideas."

Was there a gap between what you expected research/founding to be and what you actually experienced?

There was a substantial gap between the research solutions presented in academic papers and those that are practically deployable in industry. In practice, many additional requirements must be considered—requirements that I was not fully aware of at the outset. For instance, when a company or organization seeks to deploy a security architecture, product security certification is often a prerequisite. In academia, by contrast, greater trust is typically placed in theoretical analysis and formal verification, as these methods allow us to assess the security of an architecture in a more rigorous, transparent, and logically grounded manner, rather than relying primarily on institutional or regulatory authority.

 

What specifically motivated you to join the Founders Fellowship at CISPA Helmholtz Center for Information Security?

The benefits provided by the Fellowship are both substantial and compelling, and they were a decisive factor in my decision to pursue the program.

I strongly believe that one of the most critical challenges in founding a startup lies in effectively managing the initial stage of risk. Early-stage ventures are inherently uncertain, and the ability to explore, test, and refine ideas without excessive financial or operational pressure is often what determines whether an idea can meaningfully develop into a viable product or organization.

In this regard, the program offers a uniquely supportive environment that significantly reduces constraints at the early stage. It creates a structured “safe space” where participants can explore and validate their ideas without bearing an immediate financial burden, while also benefiting from financial support through the Fellowship itself. This combination meaningfully lowers the barrier to experimentation and allows founders to focus more fully on innovation and learning.

Beyond this foundational support, the Fellowship also provides a comprehensive ecosystem of additional resources. These include high-quality feedback from experienced mentors, access to valuable professional networks, and assistance with grants, funding opportunities, and travel-related expenses. Collectively, these elements form a strong support structure that not only reduces risk but also actively enhances the likelihood of meaningful progress and impact.

Was there a particular moment or conversation that convinced you?

No, I was convinced by the calling poster :) 

 

Tell me about your startup idea.

We provide a next-generation authentication and identity verification platform that delivers phishing-resistant authentication while preserving privacy and usability. The system combines modern cryptographic authentication methods with secure identity verification and delegated authentication mechanisms. By enabling secure authentication without relying solely on dedicated hardware tokens, the platform reduces deployment costs and improves deployment feasibility while maintaining strong cryptographic security guarantees.

The key innovation of the project lies in integrating phishing-resistant authentication, privacy-preserving identity verification, and scalable authentication-as-a-service infrastructure into a unified framework. The system leverages advanced cryptographic protocols, secure isolated hardware components (Trusted Execution Environment), and secure authentication mechanisms inspired by FIDO2 standards while enabling flexible delegation and recovery capabilities that are currently missing in existing deployments.

 

How has your daily life or way of thinking changed since joining the fellowship?
I am still myself—perhaps I just have to dress more formally than usual. :)

 

What kind of support has been most valuable to you so far?

There are several examples I could provide.

First, the fellowship offers valuable technical support by connecting me with opportunities such as grants, funding, and potential pilot clients.

Second, the fellowship facilitates participation in conferences, workshops, or courses, as well as travel, enabling me to attend relevant events it recommends. These events provide valuable opportunities to build new connections, gain fresh technological insights, and better understand current market trends.

Finally, and most importantly, the fellowship provides highly valuable feedback on the product. This feedback is consistently rigorous and insightful, yet always constructive rather than discouraging. It creates a strong sense of collaboration, as though we are working together to refine and strengthen both the idea and the product.

 

If your startup is successful in five years, what will have concretely changed?
Our goal is to fundamentally shape the way online authentication and identity management are designed and practiced. We aim to contribute to a future in which individuals can participate in digital ecosystems with confidence, without unnecessary concern about security, privacy, or identity misuse. 

 

And if you complete the sentence: “Founding a company means to me…” — how would you finish it?

​Idk, just want to do it I guess :)
