Information-Theoretic Cryptography
Conference on Information-Theoretic Cryptography
ITC is an annual research conference devoted to information-theoretic security and to the mathematical ideas that connect cryptography with coding theory, information theory, privacy, quantum information, and theoretical computer science.
About ITC
Information-theoretic cryptography studies security against computationally unbounded adversaries. It includes protocols with unconditional guarantees, as well as information-theoretic methods used to understand computational and quantum security.
The conference provides a dedicated venue for rigorous work in this area and encourages sustained exchange among neighboring research communities.
