There are 1024 bytes in a kilobyte write an expression using exponents

Posted in Uncategorized A more recent version of this article can be found here. When we discuss data volumes in electronic discovery, we typically speak in terms of kilobytes, megabytes, gigabytes and sometimes even petabytes, at least for very large matters.

Having a Glossary meant I could reduce the text on most pages, while expanding background for the definitions, and relating the ideas to other similar, contradictory, or more basic ideas. Why Bother with Definitions?

Terry Ritter

The value of a definition is insight. Simple descriptions are not always possible. Terms have meaning within particular contexts. Tedious examples may be required to expose the full meaning. Good definitions can expose assumptions and provide a basis for reasoning to larger conclusions. Consider the idea that cryptography is used to keep secrets: We expect a cipher to win each and every contest brought by anyone who wishes to expose secrets.

We call those people opponentsbut who are they really, and what can they do? In practice, we cannot know. Opponents operate in secret: We do not know their names, nor how many they are, nor where they work.

Terry Ritter

We do not know what they know, nor their level of experience or resources, nor anything else about them. Because we do not know our opponents, we also do not know what they can do, including whether they can break our ciphers.

Unless we know these things that cannot be known, we cannot tell whether a particular cipher design will prevail in battle. We cannot expect to know when our cipher has failed.

Even though the entire reason for using cryptography is to protect secret information, it is by definition impossible to know whether a cipher can do that. Nobody can know whether a cipher is strong enough, no matter how well educated they are, or how experienced, or how well connected, because they would have to know the opponents best of all.

The definition of cryptography implies a contest between a cipher design and unknown opponents, and that means a successful outcome cannot be guaranteed by anyone.

Sometimes the Significance is Implied Consider the cryptographer who says: First, the cryptographer has the great disadvantage of not being able to prove cipher strength, nor to even list every possible attack so they can be checked.

In contrast, the cryptanalyst might be able to actually demonstrate weakness, but only by dint of massive effort which may not succeed, and will not be compensated even if it does. Consequently, most criticisms will be extrapolations, possibly based on experience, and also possibly wrong. The situation is inherently unbalanced, with a bias against the cryptographer's detailed and thought-out claims, and for mere handwave first-thoughts from anyone who deigns to comment.

This is the ultimate conservative bias against anything new, and for the status quo. Supposedly the bias exists because if the cryptographer's claim is wrong user secrets might be exposed. But the old status-quo ciphers are in that same position. Nothing about an old cipher makes it necessarily strong.

Unfortunately, for users to benefit from cryptography they have to accept some strength argument. Many years of trusted use do not testify about strength, but do provide both motive and time for opponents to develop secret attacks.

Many failures to break a cipher do not imply it is strong. There can be no expertise on the strength of unbroken ciphers. So on the one hand we need a cipher, and on the other have no way to know how strong the various ciphers are.

For an industry, this is breathtakingly disturbing. In modern society we purchase things to help us in some way. We go to the store, buy things, and they work. Or we notice the things do not work, and take them back.

We know to take things back because we can see the results. Manufactured things work specifically because design and production groups can test which designs work better or worse or not at all.there are bytes in a kilobyte.

A Ciphers By Ritter page. In Data storage and when describing memory size, a Kilobyte is 2^10, or bytes. Bytes are always some multiple or exponent of two. 1 byte (B) = 8 bits (b). Properties of Exponents Since 1 megabyte is kilobytes, and 1 kilobyte is bytes, you can multiply to determine the number of bytes in the eBook: 1 MB 5 ()() 5 1,, bytes denominator and the exponents in the simplified expression?
