- Consider the case of Alice sending a message, m, to Bob. Both Alice and Bob use public key cryptography and each has a public and private key as described in the text. The figure attached below shows the operations that Alice must perform to provide confidentiality, authentication, and integrity when sending a message to Bob over the network. We can use either symmetric key or public key cryptography to encrypt a message. For our purposes, either technique will encrypt the message, and applying both doesn't make it "more secure". Also, we can assume that the session key would remain a secret so the fact that it is discarded does not make it "more secure". Why do we use a session key, Ks, instead of relying only on public key Cryptography? In other words, why do we use both public key and symmetric key cryptography?Decrypt: Encryption and decryption are mathematical inverses using the Caesar/Rail Fence Cipher Key is 0x7F in hexideIf P= 13 and q = 17 apply the Complete Public key cryptosystem using RSA
- Explain how encryption secure passwords and write a program using either java or python of a hash function that can be used for passwords and give illustration to show how a hash function in cryptography works.A password system uses exact 8-character of alphanumeric. To be a secure password system, any password cannot contain the following keywords: (a) All numbers. I.e., must contain at least one letter in the password. (b)User's name. What is the probability of an adversary guessing John Hank's password correctly?Define hash as it relates to cryptography. Give one example of where a hash algorithm might be used. Name one specific hash algorithm.
- Perform encryption and decryption using the RSA algorithm for the following. Show allyour steps.1. p = 3; q = 11, e = 7; M = 52. p = 5; q = 11, e = 3; M = 9Perform encryption and decryption using the RSA algorithm for the following: a) p=19; q=23; M = 2; b) p=7; q=31; M = 3;. Q: There is no authentication in the Diffie-Hellman key-exchange protocol. By exploiting this property, a malicious third party, Chuck, can easily break into the key exchange taking place between Alice and Bob, and subsequently ruin the security. Explain how this would work.
