　Laboratory of Cryptography and Information Security

■SCOPE
Privacy violations, personal information leakage, computer viruses, DDoS attacks and other computer crimes have recently become serious security problems among information systems. To solve these problems, various information security technologies like cryptography or authentication are essential as tool. These technologies are also indispensable to develop for new cyber business. We have been researching theory of cryptography, authentication and network security technology and their implementations.
