It’s fun to uncover something that you aren’t supposed to know about—
many software applications and movies on DVD contain what are known
as “easter eggs.” However, imagine finding something that you aren’t supposed
to find that turns out to be useful and informative.
In this chapter, we are going to hunt for GPS easter eggs, delving into the
secrets that lie behind the standard menus on your GPS unit to find useful
features and diagnostic screens that can give you information about your
system and troubleshoot problems that you might have.
Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries
“Aaron was part of an army of citizens that believes democracy only works when the citizenry are informed, when we know about our rights—and our obligations. An army that believes we must make justice and knowledge available to all—not just the well born or those that have grabbed the reins of power—so that we may govern ourselves more wisely. When I see our army, I see Aaron Swartz and my heart is broken. We have truly lost one of our better angels.” - C.M.
The internet is ever growing and you and I are truly pebbles
in a vast ocean of information. They say what you don’t
know can’t hurt you. When it comes to the Internet
believe quite the opposite. On the Internet there a millions and
millions of computer users logging on and off on a daily basis.
Information is transferred from one point to another in a
heartbeat. Amongst those millions upon millions of users, there’s
As humble a user you may be of the Internet, you are pitted
against the sharks of the information super highway daily.
In this age of universal electronic connectivity, of viruses and hackers, of
electronic eavesdropping and electronic fraud, there is indeed no time at
which security does not matter. Two trends have come together to make the
topic of this book of vital interest. First, the explosive growth in computer
systems and their interconnections via networks has increased the depen-
dence of both organizations and individuals on the information stored and
communicated using these systems.
Typically, these actors attempt to exploit flaws in the system implementation or its deployment in order to
obtain information, acquire access to services, or simply to disrupt the operation of the cloud through loss of
system availability or system and information integrity. As the description of these attacks implies, some of
these attacks violate the tenant boundaries and hardware abstraction layers that VMware vCloud Director
attempts to enforce.
Using certiﬁcates also opens up for the possibility of removing the key transfer
between Alice and Bob completely! This is an important feature when secure
communication is being implemented between a large number of participants. This
is because none of Bob’s ability to trust the public key he receives now depends on
whether he is actually communicating with Alice or not. His ability to trust the key
depends solely upon his trust relationship with the trusted third party.
