- please try to understand the question and provide the correct answer i will give thumb up (like) if your answer is correct and suitable I NEED A VERY GOOD ANSWER AND GOOD EXPLAINITION....I ALREADY POSTED THIS QUESTION BUT NOW I MAKE EASY FOR IT PLZ HELP ME WITH THIS ASAP RSA (Rivest–Shamir–Adleman) and AES (Advanced Encryption Standard) are two different types of ciphers. You are now given two large primes, p and q, a cryptographic hash function H(x).a) DESCRIBE the RSA algorithm. In your description, you should make clear how RSA keys are generated, how a message is encrypted and how a cipher text is decrypted.1. Asymmetric Encryption and Message Authentication: a) The primitive root of a prime number is the basic principle of Diffie-Hellman. i) Is 3 the primitive root of 11? Show the proof with your calculation. ii) What are the important criteria for selecting a prime number in cryptography? Is 11 a good choice for such a purpose? b) Find the parameters stated using the Diffie-Hellman methods, given the user A and B shared a prime number and its primitive root of 23 and 5, respectively. i) If user A public key value is 8, find the A’s private key. ii) If user B public key value is 19, what is the common secret key? c) In the following scenario, we will compare the security services that are given by digital signatures (DS) and message authentication codes (MAC). We assume that James can read all messages send from Chan to Badrul and the other way around, too. James has no knowledge of any keys but the public one in the case of DS. State whether and…Can you explain more about this question 1. How many passes should you do if the keys were all different? Answer here: Minimum 200 words where you discuss the specific implications (i.e., I don’t want a hunch or opinion, base it on facts…maybe use math). I’m understanding that any modern cipher should be secure with one pass. We should have only one pass because any modern cipher should be secure with one pass. The ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking.so, we do have only one pass.
