The DSA digital signature scheme discussed in class employs global public-key co

The DSA digital signature scheme discussed in class employs global public-key
components and an individual secret key. For every message to sign DSA also requires an integer
k. Why does k have to be random and unique to every signing? Explain specifically what can go
wrong if it is not random or not unique respectively (so you should discuss these two scenarios
separately).

What is the output of the first round of the DES algorithm when the first and last bits of plaintext’ and the key bits are ones, and the remaining bits are zero? Show your work (How to generate keys and each step until the output of the first round).

1- What is the output of the first round of the DES algorithm when the first and last bits of plaintext’ and the key bits are ones, and the remaining bits are zero? Show your work (How to generate keys and each step until the output of the first round).
2- An avalanche effect is also desirable for the key: A one-bit change in a key should result in a dramatically different ciphertext if the plaintext is unchanged.
Assume an encryption with a given key. Now assume the key bit at position 1 (prior to PC − 1) is being flipped. Which S-boxes in which rounds are affected by the bit flip during DES encryption?
Which S-boxes in which DES rounds are affected by this bit flip during DES decryption?

Beforepay goes for the broke with late-season IPO

A stream cipher uses a LFSR with three units. An attacker captures a ciphertext “0101001010011”. The attacker knows that the first 6 bits of the message are “110001.” Using this information, the attacker defeats this encryption, i.e., he is able to determine the initial seed values (S1, S2 and S3) and Keys (K1, K2 and K3). What are those values?
