◆Research Interests

Our research interest is in information security and number-theoretic Algorithms :
Information security
New threats like hackers, computer crimes, tapping, forgeries, etc. have become serious problems. Information security aims at protecting electronic information against such threats. I have been studying information security, especially in cryptographic protocols such as signatures, and key agreements. My interests also include its applications like network security and copy protection.
Number-theoretic Algorithms
Number-theoretic algorithms are an important base of public key cryptography, which concerns both its efficiency and its security. I have studied arithmetic algorithms like addition chain and security about the discrete logarithm problem and the elliptic curve discrete logarithm problem.
