Student Interviews

I aim to be a key player in building a more efficient and secure SCM using blockchain and AI.

Introducing homomorphic encryption to ensure anonymity,
Examining the security challenges

I am working for the Mitsubishi Chemical Holdings Group, researching the development of systems using the latest technologies in the digital field. I am involved in a project to build the next generation of SCM (Supply Chain Management) in the company. This SCM envisages the introduction of blockchain to improve traceability and convenience. I enrolled in IISEC to acquire the necessary expertise. At IISEC, I am guided by Prof. Otsuka, who is an expert in cryptographic protocols and IoT security. In a decentralised environment such as a traditional blockchain, data is less likely to be tampered with and recovery is relatively easy. On the other hand, there are some disadvantages, such as the fact that data is shared and anonymity cannot be maintained. This is why I am investigating blockchains that can provide both convenience and privacy protection, using a technology called homomorphic encryption. With this type of cipher, the encrypted data can be processed as it is.

My goal is to use AI and IoT technology in my business and improve my own skills

I go to IISEC twice a week, the first is on research guidance days when the whole lab members gather, and the second is on individual guidance days with Prof. Otsuka. My seniors and fellow students in the same lab are working on cryptocurrencies and AI. Listening to their presentations, on guidance days, gives me many hints. This is one of the strengths of IISEC's multifaceted research with information security at its core. My goal is to catch up with the rapidly evolving technologies of AI and IoT, to apply them to my work with a view to new business, and to improve my own skills as well. I see my PhD is a pathway to achieving those challenges.
