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:
(a)Applications Time Stamp Events
(b)S=0.5(W-
)+
, where
≤W≤
+8.
Explanation:
Some applications assume that clocks always advance, so they could timestamp events under this assumption.
In our case we have the wrong timed clock, say W and the hardware clock H which is supposed to advance at a perfect rate.
We proceed to construct a software clock such that after 8 seconds we can replace the wrong timed clock with the software clock in good conditions.
Let us denote the software clock with S.
Then, S=c(W-
)+
where:
=The current Time(10:27:54) and;
c is to be found.
We already know that S=
+4 when W=
+8,
So:
S=c(W-
)+
+4=c(
+8-
)+
4=8c
c=0.5
We obtain the formula
S=0.5(W-
)+
, where
≤W≤
+8.
In python the % operator is modulo. Modulo returns the remainder of two numbers.
19 % 5 = 4 therefore,
print(x%y) would output 4
I guess the answer would be B if it was a choice.
