decrypt the ciphertext xyatqyvaxpagjdpglax encrypted by the affine cipher. also explain is there alphabets which will not change after ecnryption

Expert Solution

Here this table shows the ciphertext letter for each of the plaintext letter that is given in alphabetic order. Here we have to perform (5x+8)mod 26 to find the ciphertext of the given plain text letter,where x is the number given for each of the plaintext letter and that is given in alphabetic order starting from 0, so A has 0 value and Z has value 25. Then perform (5X+8)mod26 to find a number and then write the letter that is represented by that number.Then we get the ciphertext.

Herer ciphertext is xyatqyvaxpagjdpglax

corresponding plaintext after referring table is dyoxmynodrokvzrklod

here if we look at this plaintext we can see that for the ciphertext letters y and l we are getting the same letters to represent plain text.

Suppose an attacker obtained 128 bits of ciphertext that were encrypted using an encryption algorithm whose keys are known to be 128 bits long. How effective is an exhaustive key search if the attacker does not know the encryption algorithm used? Provide an example of when data integrity is more important than data confidentiality? Suppose you have been asked at your new job to recommend the strength of encryption needed to protect the contents of a database. Draw up a...

Cyrptography*** Suppose you saw a ciphertext stream that you know was encrypted with DES-CBC, and you observed that C3 = C6(i.e., the third and sixth output ciphertext blocks were the same).What information does this tell you about the plaintext input?

Part 1: Design a Cipher allow user to use a “key” to encrypt and decrypt the message. Use at least two ciphers combined to design your own cipher Specify the min. and max. length of the message user can enter to encrypt Specify the length of the “key” user can enter to encrypt and decrypt the message Part 2: Programme the cipher and make it available to validate. Cleartext for the original programming scripts has to submitted. A frontend webpage...

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. Given an arbitrary cipher text file, you need to write a C++ program to find out the value of the shift going down the...
