AboutAbout the lab
Research on secure multimedia information and communication networks.
The Ohama-Santoso Lab studies the efficiency, reliability, and security of information and communication networks, from fundamentals to applications.
Its research theme is "secure multimedia information and communication networks," covering both communication mechanisms and cryptographic and authentication mechanisms.
The lab attempts to build and analyze service and communication systems, and also aims to develop an engineer's intuition about the limits and possibilities of communication networks.
As research fields, Professor Ohama lists information theory, and Associate Professor Santoso lists information security and cryptography.
Key terms
- Ad hoc network
- A communication network formed by terminals connecting directly to one another, without relying on fixed facilities such as base stations
- Network coding
- A method of encoding data at relay nodes in a network before sending it on. Here, it is used for multicast communication
- Provable security
- The property that a cryptographic or authentication scheme can be shown mathematically to be secure
