Write Matlab program to find secrecy and authentication of message using RSA algorithm.

What is the output of the first round of the DES algorithm when the plaintextand the key are both all ones? SHOW THE WORK

Please identify the correct statement(s) for operation modes. IVs can be sent from the sender to the receiver in plaintext. In other words, it is OK for IVs to be visible to the attacker. If two plaintexts are the same, their ciphertexts after CBC will be the same if CBC uses a constant value for IV (i.e., the IV value does not change). If two plaintexts are the same, their ciphertexts are ECB will be the same. It is secure for CFB to reuse IVs for efficiency improvement.

ONLY THE TAP BITS. The notation from this problem is from Understanding Cryptography by Paar and Pelzl. We conduct a known-plaintext attack against an LFSR. Through trial and error we have determined that the number of states is m=4m=4.The plaintext given by 01001011=x0x1x2x3x4x5x6x701001011=x0x1x2x3x4x5x6x7 when encrypted by the LFSR produced the ciphertext 11010110=y0y1y2y3y3y5y6y711010110=y0y1y2y3y3y5y6y7. What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g. 0101 to represent p3=0,p2=1,p1=0,p0=1p3=0,p2=1,p1=0,p0=1).

Please explain the problem in detail so that I can understand.

dont dont dont post copied one sure strict report skip if dont know

Entrapment applies to honeypots, since they induce the attacker to break into the system Group of answer choices True False

Let's pretend a Vigen'ere cipher was used to encrypt a long string of text, and that the encrypted text included many instances of the same string. Describe the methods you'll use to calculate the length of the key based on this information.

A block cipher with a random key is most like a Choose one: Private random function Public random permutation Private random permutation Public random function

Show all of the steps needed to encrypt and decrypt the ASCII message “YES” without a modular arithmetic calculator in an RSA cipher with public key (143, 7).
