Using randomized encryption, convert an AES and RSA message (m) with 128 bits into a secured version with an initialization vector (IV). Show how to encrypt (m) with secured AES.

Expert Solution

Initialization Vector:

Initialization vector is a arbitrary number, can be used along with a secret key for encryption of data.This vector is a number which is added to a secret key. It generates only once in a session. It is a 24 bit key. It is added along with Wep (Wired equivalent privacy) key which size is 40 bit making a sum of 64 bit key.

Using a technique called randomized encryption, convert textbook AES and RSA to a secured version with an initialization vector (IV). Assume we have a message (m) with 128 bits, show how to encrypt (m) with secured AES. Explain why IEEE 802.11 (i.e., WEP) is not secure due to the inappropriate usage of an IV.

When applying secured AES to a long message (multiples of 128 bits), it will have different modes of encryption. Show all the recommended AES modes of encryption with a 256-bit message m = m1m2. Include a diagram as well.

Suppose an attacker obtained 128 bits of ciphertext that were encrypted using an encryption algorithm whose keys are known to be 128 bits long. How effective is an exhaustive key search if the attacker does not know the encryption algorithm used? Provide an example of when data integrity is more important than data confidentiality? Suppose you have been asked at your new job to recommend the strength of encryption needed to protect the contents of a database. Draw up a...

Alice wants to send a plaintext message m = 10 to Bob secretly using RSA public key cryptosystem. Bob selects p = 7, and q = 13 with e = 5. You have to perform following tasks: a. Compute and list Bob’s public and private keys. b. Compute the ciphertext that Alice will send to Bob using plaintext message m = 10. c. Recover the actual plaintext from the ciphertext sent by Alice
