Components of Cryptanalysis What are different components of Cryptanalysis. I can't seem to find them. Are they the same as Cryptosystem or is there any difference.

TL;DR: The question does not really make sense. Because you cannot put things into boxes like that.

The best way to make you understand it is to make an analogy. Cryptosystem is to Chess what Cryptanalysis is to Chess Games Strategy/Reviewing.

As you define a Cryptosystem with the following components:


Plaintext
Encryption Algorithm
Ciphertext
Decryption Algorithm
Encryption Key
Decryption Key


You can define Chess with:


a 8x8 board
16 white pieces (King, Queen, 2 Rooks, 2 Bishops, 2 Knights, 8 pawns)
16 black pieces idem.
a set of rules


And you can see the review and strategy as:


Openings moves and tactics (Alekhine's Defence, Caro-Kann Defence, King's Gambit...),
Midgames moves and tactics,
Endgames  and tactics,
Mat in 3 (and more),
pinning,
forks,
discovered attacks
etc.


Cryptanalysis will be the art to look at a cryptosystem, find it's weaknesses and how to improve it:


differential/linear/integral Cryptanalysis,
boomerang attacks, related key attacks, impossible differentials,
birthday bounds,
Meat-in-the-middle attack,
Game-based proofs,
Shor's/Simon's/Grover's algorithm
etc
