Machine-translated · View original
A lab that researches coding techniques to make computers resistant to errors and efficient.

AboutAbout the lab
Correcting data errors with the power of codes.
Haruhiko Kaneko Lab studies coding techniques that make computer systems highly reliable and efficient.
One of them is error-control codes, which detect and correct data that has been corrupted during storage or transmission.
The codes it works on are wide-ranging, including synchronization error correction, constrained codes, LDPC codes, and polar codes.
The lab also works on data compression, code-based post-quantum cryptography, and dependable computing.
Key terms
- Error-control codes
- Codes that add redundant information to data in advance so that parts corrupted along the way can be detected and restored
- LDPC codes
- A type of error-control code. It can correct many errors with a small combination of checks, and is used in communications and storage devices
- Post-quantum cryptography
- Cryptography whose methods are believed to resist attacks even once quantum computers become practical. Also called PQC
ResearchResearch themes
To build computer systems that are resistant to errors and efficient, the lab studies codes that correct data errors, along with data compression techniques. Its themes range from error-control codes to post-quantum cryptography and dependable computing.
*Illustrative imageError-control codes
The lab studies codes for detecting and correcting errors that occur in data during storage or transmission. It works on synchronization error correction, constrained codes, LDPC codes, and polar codes.
*Illustrative imagePost-quantum cryptography
The lab studies cryptography that is hard to break even once quantum computers become available. Its themes are code-based public-key cryptography and QC-MDPC codes.
*Illustrative imageDependable computing
From the side of coding techniques, the lab studies how to build computer systems that can be trusted even when errors or faults occur.
