That is a statement. Hope that helped you. :)
The answer is very simple: no. No, we have not achieved full equality with regards of race. No, we should not feel like we have achieved such a thing. But, everyone’s answers will vary. Some might think that we have, some might think that we haven’t (which is the most intelligent answer, it shows that some people aren’t naive and/ or living in their own little world,) and some might not even care. Many forms of discrimination still exist in the world we live in today. Why would anybody “feel” as if we’ve already achieved any sort of equality when people (not all) are still going after others for something as simple and the color of their skin? Their culture? The country they’re from? The real question is; will we ever TRULY achieve equality?
I think the questions that must be ask are:
a.What does “encryption” mean?
d.What are “key distribution problems”?
All the text is based on the concept "encryption" so it is very important to know what it means in order to undestand the rest of the information. If not, you will be missing important facts. In addition, there are a lot of words used that are derived from this one, so you won't be able to undestand them.
Another important concept that gives a lot of information just by knowing it's meaning is "key distribution problems", they could be two or a thousand, it is important to know what they are and what they do.
The other question that seems important is the one of the "public key cryphtography" but this one can be inferred by the context.
