Sakiyama-Li-Miyahara Lab
Machine-translated · View original
The lab studies information security, with a focus on cryptographic technology.
AboutAbout the lab
Studying information security, centered on cryptography.
The Sakiyama-Li-Miyahara Lab studies security measures centered on cryptographic technology, as well as information security based on new concepts.
The lab's website explains that attacks on information systems are a growing threat in the real world, and that increasingly sophisticated attackers cannot be ignored.
Together with the Sugawara Lab and the Iwamoto-Watanabe Lab, the lab pursues next-generation security systems that increase the resilience of information infrastructure.
For undergraduate thesis research, the lab accepts assignments in two separate groups: the Sakiyama-Miyahara Lab and the Li Lab.
Key terms
- Side-channel analysis
- Analysis that extracts secret information inside a device from physical information such as power consumption and electromagnetic emissions produced while the device operates
- Card-based cryptography
- A type of cryptography that uses physical cards, such as playing cards, to perform computations or proofs without revealing secrets
- Resilience
- The ability to keep functioning and recover even after an attack or failure
