An encryption protocol with information-theoretic security is impossible to break even with infinite computational power. Protocols proven to be information-theoretically secure are resistant to future developments in computing. The concept of information-theoretically secure communication was introduced in 1949 by American mathematician Claude Shannon, one of the founders of classical information theory, who used it to prove the one-time pad system was secur… Webb16 jan. 2024 · In cryptography the gold standard of security, “perfect security” is a special case of information-theoretic security wherein for an encryption algorithm, if there is ciphertext produced that uses it, no information about the message is provided without knowledge of the key.

Webbtheoretical cryptography often takes the secrecy assumption for granted, but as we have seen, there are a bevy of ways that the secrecy assumption can fail in real systems. One possible reaction is to study implementation techniques that ensure the secrecy assumption will always hold. For instance, we can consider adding large capacitors
