WebbSome main differences between Confusion and Diffusion are as follows: Confusion is a cryptography technique used to generate the vague ciphertext. On the other hand, diffusion is employed to create cryptic plain texts. The diffusion attempts to make the statistical relationship between ciphertext and plaintext as complex as feasible.

WebbWhile most of Cryptography is based on the assumptions of the hardness of speci c problems, basing Cryptography on P 6= NP is no longer cherry-picked but instead achieves a structural theorem relating the the existence of Cryptography to the hardness of a natural class of problems. This would show that NP’s WebbIn fact, Shannon’s proof that perfect secrecy requires a secret key of the same length as the plaintext is often taken as evidence that unconditional security can never be practical.

To characterize the events’ importance from a probabilistic perspective, the message importance measure (MIM) is proposed as a kind of semantics analysis tool.

He used this algebra of logic to analyze, and then synthesize, switching circuits and to prove that the overall circuit worked as desired. bim 360 broken file iconWebbnication theory of secrecy systems” [6].

"WebbCryptography is the science, at the crossroads of mathematics, physics, and computer science, that tends to design protocols to prevent malicious third-party from reading private messages. Even if the development of computers during the 20th century made the research in cryptography explode, the use of cryptographic methods was common before. " - Shannon's theory in cryptography
