Information Security (Collaborative Unit) Lab
Machine-translated · View original
The lab supports a secure networked society through cryptography, from theory to the security of implementations.
AboutAbout the lab
Realizing a secure networked society through cryptography.
The Information Security Lab (Abe-Tibouchi Lab) is a collaborative field launched through cooperation and partnership between Kyoto University and NTT. Research supervision is provided by NTT's Visiting Professor Masayuki Abe and Visiting Associate Professor Mehdi Tibouchi.
Now that the Internet has become vital social infrastructure, information security is essential to keeping society running, and cryptography is its foundation. The lab studies a broad range, from the theory of fundamental security to proposals of applied protocols, with an eye toward post-quantum cryptography for the era of quantum computers.
The lab is located in Integrated Research Building No. 7 on the Yoshida Campus, and students interested in security gather there from Japan and abroad.
Key terms
- Digital signature
- A cryptographic technique that makes it possible to verify that data has not been tampered with and who created it
- Zero-knowledge proof
- A method of proving only that you know a secret, without revealing its contents
- Secure computation
- Technology that allows multiple computers to carry out a computation without revealing their data to one another
- Post-quantum cryptography
- Cryptography designed to be hard to break even with quantum computers
ResearchResearch themes
The lab pays particular attention to digital signatures, zero-knowledge proofs, and secure computation, which are used in blockchains, crypto-assets, electronic payments, and electronic voting.
*Illustrative imageSecurity Theory and Protocols for Cryptography
The lab studies digital signatures, zero-knowledge proofs, secure computation, and more, from the theory of fundamental security to proposals of applied protocols. It looks ahead from current cryptographic technology to post-quantum cryptography for the era of quantum computers.
*Illustrative imageEvaluating Implementation Security
Cryptographic technologies can carry security concerns when implemented, separate from those in the theory. Evaluating this implementation-level security is also an important theme for the lab.
