Cyber Security Systems Question:
Answer:
C. Byte oriented stream cipher
Explanation:
RC4 is a variab key-size stream cipher with byte-oriented operations. The algorithm is based on the use of a random permutation.

2. Use the 3-bit block cipher in the table below to answer the following. Suppose the (a) Use the block cipher without cipher-block chaining (CBC) to encrypt the message (b) Suppose Trudy intercepts the ciphertext. Further suppose she knows that the text was plaintext is m 011011011. What is the resulting ciphertext? encrypted with a 3-bit block cipher without CBC, but she does not know the specific cipher. What can she determine about the original message? (c) Now use the...
