Cryptography with information theoretic security
H. Imai, Goichiro Hanaoka, Junji Shikata, Akira Otsuka, Anderson C. A. Nascimento · 2003
Summary form only given. We discuss information-theoretic methods to prove the security of cryptosystems. We study what is called, unconditionally secure (or information-theoretically secure) cryptographic schemes in search for a system that can provide long-term security and that does not impose limits on the adversary's computational power.
