Once an action is performed, it may not be undone even if it has not been too long.
This property is referred to as:
Unmotivated user property
Barn door property
Abstraction property
O lack of feedback property
O None of the above
Question 5
One time pad is provably secure because:
Onetime pad uses finite length key
O Onetime palihuses 256 bit keys
Onetime pad employs both substitution and tranposition
In a onetime pad system, a key is never reused. Assuming that the key stream is
random, the ciphertext is random as well, thus ensuring provable security
None of the above
