About Me

I'm Yoshi, a student researcher investigating how confidential computing and hardware-based trust can reshape cloud infrastructures. I'm currently a junior majoring in Computer Science & Communications Engineering at Waseda University, where I focus on secure systems research. My work lies at the intersection of confidential computing, trusted execution, and distributed systems.

I am a member of:

• Kimura-Kasahara Laboratory, Green Computing Systems Center - Securing cloud workloads while making them more useable and flexible with IO devices.
• Internet Initiative Japan (IIJ) Research Laboratory - In collaboration with Imperial College London's LSDS Group, applying serverless workloads to confidential computing infrastructures.

Research

In a world where data is the new currency, trust and privacy are no longer optional — they're foundational.

I'm driven by the question: How do we build cloud infrastructures that are not just fast and scalable, but fundamentally trustworthy? At the intersection of hardware, software, and virtualization security lies a uniquely complex trust problem. My research addresses this through confidential computing and its real-world integration.

Current Research Projects

1. GPU Passthroughs for TDs - Measuring DMA-buffer overheads to unlock high-performance accelerated workloads inside Intel TDX VMs.
   Keywords: Intel TDX, NVIDIA GPU, CUDA.
2. Serverless Confidential Containers - Researching Kubernetes serverless deployments on confidential computing infrastructure.
   Keywords: K8s, Knative, Confidential Containers (CoCo), Kata Container, Intel TDX, AMD SEV-SNP.

Research Interests

• Confidential Computing
• Secure Distributed Systems (e.g. serverless)
• Privacy-Preserving Computation for Bioinformatics
• Federated Learning, Privacy-Perserving LLMs
