Kurihara Lab
Machine-translated · View original
A lab that protects communication privacy through both theory and implementation.
AboutAbout the lab
Making networks secure and private.
The Kurihara Lab studies the building-block technologies and protocols for security and privacy that will be essential to future network infrastructure.
The lab approaches the problem from both theory and implementation. In fundamental areas, it builds protocols based on coding theory.
In applied areas, it studies new network architectures and their anonymization and authentication protocols.
Key terms
- Protocol
- The set of rules for the procedure of exchanges that communicating parties follow
- Coding Theory
- A field that uses mathematics to study how to convert data into forms that are resistant to errors and eavesdropping
- Secret Sharing
- A mechanism that splits secret data into multiple pieces so that it can be restored only when at least a set number of pieces are gathered

*Illustrative imageAnonymization Protocols for Communication
The lab designs, implements, and evaluates anonymization protocols for the Internet that are lighter-weight and harder to break even when multiple parties collude. Targets include protocols that anonymize DNS, and the lab also evaluates performance in testbed environments.
*Illustrative imagePrivacy Protected by Coding Theory
Using techniques from information theory and coding theory, the lab studies communication protocols and methods for protecting security and privacy. Focusing on subjects such as secret sharing, it determines the theoretical limits and considers how to achieve them.
*Illustrative imageInformation-Centric Networking
The lab studies efficient protocols and new security mechanisms for information-centric networking (ICN).
*Illustrative imageComputation on Untrusted Infrastructure
The lab studies the mathematical frameworks for new computing architectures such as in-network computing and edge computing, as well as methods for protecting users' privacy on untrusted computing infrastructure.
