Alice wants to send a message m to Bob using Rabin Cryptosystem. Bob makes the public key n = 77 and sends it to Alice. By using Rabin Cryptosystem, a) Alice encrypts her message m and sends the encrypted message c to Bob. What are the encrypted messages if m = 8, 36, 41 and 69? b) Alice encrypts her message m = 6 and sends the encrypted message c to Bob. Bob decrypts the message. What are the possible...
your answer. Refer to attack scenarios on mutual authentication protocols that were discussed during the Lecture-7 and Tutorial-7.] 5 Marks] Q5 (OpenSSL and IPFS) Assume that the School of Science of RMIT University is planning to use IPFS-based repository of sensitive files for sharing among staffs. An owner of a particular file, say Alice wants to share the file to her supervisor, say Bob. Therefore, Alice encrypts the file with Alice and Bob's shared AES secret key (KaB) using OpenSSL,...
1. Something you know (SYK) Something you have (SYH) Something you are (SYA) Something you do (SYD) are attributes that allow you to do what to a user? ___________ 2. Consider the primitive case of asymmetric encryption; no digital signature and no digital envelope. A person sends a message to a recipient using asymmetric encryption. What is the total number of keys used to send and receive the single message? _________________ 3. If the sender of a message encrypts the...
1) to verify a digital CERTIFICATE, we need the ___ a) CA's private key b) CA's public key c) certificate owner's private key d) certificate owner's public key 2) If the sender encrypts the message with the receiver's public key, it achieves the purpose of ___ a) confidentiality b) authentication c) confidentiality but not authentication d) confidentiality and authentication

Using RSA Implementation: 1. Alice's RSA public key is given by (e, n) = (59, 1189). = (a) Determine Alice's private key (d, n). (b) Bob sends his first message Mi 67 to Alice, encrypting it with RSA using Alice's public key. He obtains a cypher text Cị that gets forwarded to Alice. What is Cį? (c) Bob sends his second message M2 to Alice, encrypting it with RSA using Alice's public key. Eve, who was eavesdropping on the commu-...
Computer Engineering 4. (20 pts) If a user of a comms system wants to utilize the RSA public key encryption with p = 11 and q = 7 find their public and private keys and encrypt the message, “cyber”, using the numeric value of 1 to represent an 'a', 2 = 'b', etc. Also, show the first step in the deciphering process of this message by the user (i.e. show the first calculation based off of the received cipher for...
Use C++ forehand e receiver creates a public key and a secret key as follows. Generate two distinct primes, p andq. Since they can be used to generate the secret key, they must be kept hidden. Let n-pg, phi(n) ((p-1)*(q-1) Select an integer e such that gcd(e, (p-100g-1))-1. The public key is the pair (e,n). This should be distributed widely. Compute d such that d-l(mod (p-1)(q-1). This can be done using the pulverizer. The secret key is the pair (d.n)....
