Introduction

Hello viewers how are you all? Today I am going to discuss all the processes of Cryptographic Attacks. Basically what this attack is? How you can perform this Cryptographic Attack?

In this tutorial, I will tell how you perform Cryptographic Attack. If you are willing to know about What is Cryptography, then read my previous article or click the link below to know more about what is Cryptography?

Cryptography – What is Cryptography – Cryptography Algorithms.

What is the Cryptographic Attack?

Basically, I will tell you that, the cryptographic attacks are the techniques of performing Cryptoanalysis. First of all this attack depends on how you are performing Cryptographic Attacks.

This type of attacks also depends on what access the cryptoanalyst has over the Plaintext, Ciphertext,

Okay till now we have come to know all about, What is Cryptography. What are the Cryptographic algorithms? Alright? Now we will move on to what are the popular Cryptographic Attacks.

Replay Attack

Simply this attack means delaying a valid data transmission. you did not get it. Right? Okay, let me explain it.

Suppose you are sending your password to me as proof of identity. Now your fried ( Third user ) somehow captures the password sent by you. Now when you & I have ended communication, your friend will connect to me & will send the password as the proof of identity. Finally, Your friend will communicate with me as being you.

Ciphertext-only attack

First of all, I need to tell you that Ciphertext means Encrypted text. This type of attack is very difficult. If you are cryptanalyst & have a piece of ciphertext knowledge then you can perform this attack.

There are no obligations if you have knowledge of Plaintext or not. I already have told you that this type of attack is difficult. Because this attack involves difficult types of cryptoanalysis & requires accurate guesswork.

Also, you must know how the data would have been encrypted. Finally, you will be able to perform this attack.

Man in the middle attack

According to me, this type of attack is basically very interesting. Do you know? Because of this attack, the attacker places surveillance software between two source communication.

Therefore you can guess what happens. Yes, exactly. The attacker exchanges keys with each of the users.

Now you or I as a user will think we have exchanged key or data with each other, not with the attacker. In this way, the user sends data to the attacker unknowingly.

Known plaintext attack

Suppose you are the Cryptoanalyst. In this case, if you have a little bit of knowledge of plaintext generated from the ciphertext, then you will be able to perform a Known plaintext attack finally.

Basically the attacker uses this information to extract the key. Because it needs to recover the encrypted text.

Chosen ciphertext attack

This type of attack is basically a normal attack. Want to know why? Because, in this attack, the cryptoanalyst needs to decrypt the data. Therefore it requires finding out the key.

consequently, the cryptoanalyst selects some ciphertext ( encrypted text ) first. Then tries to match it with plaintext ( unencrypted text ). With this information, the cryptoanalyst tries to find out the key used for decryption.

Chosen plaintext attack

Through the attack the cryptoanalyst able to produce ciphertext from some plain text. This plain text becomes random.

However, the cryptoanalyst is not able to break the key which is used to produce the ciphertext.

Therefore the cryptoanalyst tries to compare the entire ciphertext with the original plaintext.
