情報理論的セキュリティに関する国際会議（ICITS 2009）

　Over the last few decades, we have seen several research topics studied requiring information theoretical security, also called unconditional security, where there is no unproven computational assumption on the adversary. (This is the framework proposed by Claude Shannon in his seminal paper.) Also, coding as well as other aspects of information theory have been used in the design of cryptographic schemes. Examples are authentication, secure communication, key exchange, multi-party computation and information hiding to name a few. A related area is quantum cryptography that predominantly uses information theory for modeling and evaluation of security. Needless to say, information theoretically secure cryptosystems are secure even if the factoring assumption or the discrete log assumption are broken. Seeing the multitude of topics in modern cryptography requiring information theoretical security or using information theory, it is time to have a regular conference on this topic.

　This is the 4th conference of this series that is aimed to bring together the leading researchers in the area of information and/or quantum theoretic security. Original research papers on all technical aspects of information and/or quantum theoretic security are solicited for submission to ICITS 2009.
