Cache-Consistent Dynamic Load Balancing for Kubernetes Controllers
Shoma Ansai, Yasuo Okabe, Daisuke Kotani
As Kubernetes clusters grow, the scalability of controllers can become a bottleneck for the performance of the system. Distributing the load dynamically across multiple controller…
Indoor Space Authentication by ISS-based Keypoint Extraction from 3D Point Clouds
Yuki Yamada, Daisuke Kotani, Kota Tsubouchi +2
We propose ISS-RegAuth, a lightweight indoor space authentication framework that authenticates a user by comparing LiDAR captures of personal rooms. Prior work processes every poin…
Distributed Tracing for Cascading Changes of Objects in the Kubernetes Control Plane
Tomoyuki Ehira, Daisuke Kotani, Yasuo Okabe
Kubernetes is a container orchestration system that employs a declarative configuration management approach. In Kubernetes, each desired and actual state is represented by an ``obj…
Mewz: Lightweight Execution Environment for WebAssembly with High Isolation and Portability using Unikernels
Soichiro Ueda, Ai Nozaki, Daisuke Kotani +1
Cloud computing requires isolation and portability for workloads. Cloud vendors must isolate each user's resources from others to prevent them from attacking other users or the who…
Monitoring Cascading Changes of Resources in the Kubernetes Control Plane
Tomoyuki Ehira, Daisuke Kotani, Hiroki Shirokura +2
Kubernetes is a container management system that has many automated functionalities. Those functionalities are managed by configuring objects and resources in the control plane. Si…
Linking Contexts from Distinct Data Sources in Zero Trust Federation
Masato Hirai, Daisuke Kotani, Yasuo Okabe
An access control model called Zero Trust Architecture (ZTA) has attracted attention. ZTA uses information of users and devices, called context, for authentication and authorizatio…
Zero Trust Federation: Sharing Context under User Control toward Zero Trust in Identity Federation
Koudai Hatakeyama, Daisuke Kotani, Yasuo Okabe
To securely control access to systems, the concept of Zero Trust has been proposed. Access Control based on Zero Trust concept removes implicit trust and instead focuses on evaluat…
Key Management Based on Ownership of Multiple Authenticators in Public Key Authentication
Koudai Hatakeyama, Daisuke Kotani, Yasuo Okabe
Public key authentication (PKA) has been deployed in various services to provide stronger authentication to users. In PKA, a user manages private keys on her devices called authent…
Acila: Attaching Identities of Workloads for Efficient Packet Classification in a Cloud Data Center Network
Kentaro Ohnishi, Daisuke Kotani, Hirofumi Ichihara +2
IP addresses and port numbers (network based identifiers hereafter) in packets are two major identifiers for network devices to identify systems and roles of hosts sending and rece…
