What is ciphertext generated by encryption of character

Assignment Help Computer Network Security
Reference no: EM1364074

A particular cipher is implemented by combining the ASCII representation of plaintext characters with pseudorandom bytes (eight-bit binary strings of 1s and 0s) using the XOR function. In the process of encrypting a message, a character in the plaintext, a capital H, is XORed with the pseudorandom byte 10111100.

a. What is the ciphertext (in binary form) generated by the encryption of the character D? (Please show your work.)

b. How is the plaintext for this encrypted D recovered? (Please show your work.)
