Question

List 3 characteristics of the ideal encryption scheme

Answer 1

Three characteristics of an ideal encrytion scheme are:
1. The encryption sheme should be strong: the algorithm is imprevious to direct attack and attempts are derived.
2. The encryption scheme should create unique ciphertext from the same plaintext for each key permutation, among other traits.
3. It should take at least millions of years to break ideal encryption scheme, based on mathematical predictions.

Answer 2

Answer:

• It must be easy to decode.

• It must be easy to encode.

• It must be difficult to crack
