What is the difference between diffusion and confusion?

In diffusion, the statistical structure of the plaintext is dissipated into long-range statistics of the ciphertext. This is achieved by having each plaintext digit affect the value of many ciphertext digits, which is equivalent to saying that each ciphertext digit is affected by many plaintext digits. Confusion seeks to make the relationship between the statistics of the ciphertext and the value of the encryption key as complex as possible, again to thwart attempts to discover the key. Thus, even if the attacker can get some handle on the statistics of the ciphertext, the way in which the key was used to produce that ciphertext is so complex as to make it difficult to deduce the key. This is achieved by the use of a complex substitution algorithm.


What is mean by diffusion and confusion in block cipher block?

Every block cipher involves a transformation of a block of plaintext into a block of ciphertext, where the transformation depends on the key. The mechanism of diffusion seeks to make the statistical relationship between the plaintext and ciphertext as complex as possible in order to thwart (hinder or prevent) attempts to deduce the key. Confusion seeks to make the relationship between statistics of the cipher text and the value of the encryption key as complex as possible, again to thwart attempts to discover the key.


What is difference between confusion and diffusion?

Confusion is a noun defined as lack of understanding, uncertainty; a situation of panic; disorder; the state of being unclear or bewildered; mistaking of one thing or person for another.Diffusion is a noun defined as the spreading of something more widely; the spreading of light from its source for the purpose of reducing glare; the intermingling of substances by the natural movement of their particles; and the dissemination of elements of culture to another region or people.More simply, confusion is uncertainty, disorder, or being mistaken; diffusion is the spreading of something.

Why cryptology a fast growing professions?

Until modern times cryptography referred almost exclusively to encryption, which is the process of converting ordinary information (called plaintext) into unintelligible gibberish (called ciphertext).[7]Decryption is the reverse, in other words, moving from the unintelligible ciphertext back to plaintext. A cipher (or cypher) is a pair of algorithms that create the encryption and the reversing decryption. The detailed operation of a cipher is controlled both by the algorithm and in each instance by a key. This is a secret parameter (ideally known only to the communicants) for a specific message exchange context. A "cryptosystem" is the ordered list of elements of finite possible plaintexts, finite possible cyphertexts, finite possible keys, and the encryption and decryption algorithms which correspond to each key. Keys are important, as ciphers without variable keys can be trivially broken with only the knowledge of the cipher used and are therefore useless (or even counter-productive) for most purposes. Historically, ciphers were often used directly for encryption or decryption without additional procedures such as authentication or integrity checks.In colloquial use, the term "code" is often used to mean any method of encryption or concealment of meaning. However, in cryptography, code has a more specific meaning. It means the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, wallaby replaces attack at dawn). Codes are no longer used in serious cryptography-except incidentally for such things as unit designations (e.g., Bronco Flight or Operation Overlord)-since properly chosen ciphers are both more practical and more secure than even the best codes and also are better adapted to computers.
