In the latter case, it took many years to find the methods Shannon’s work proved were possible. The fundamental problem of communication is that of reproducing at one point, either exactly or approximately, a message selected at another point. Information theory often concerns itself with measures of information of the distributions associated with random variables. Other bases are also possible, but less commonly used.

The entropy is maximized at 1 bit per trial when the two possible outcomes are equally probable, as in an unbiased coin toss. Between these two extremes, information can be quantified as follows. Because entropy can be conditioned on a random variable or on that random variable being a certain value, care should be taken not to confuse these two definitions of conditional entropy, the former of which is in more common use. It is important in communication where it can be used to maximize the amount of information shared between sent and received signals. Leibler divergence is the number of average additional bits per datum necessary for compression. In this way, the extent to which Bob’s prior is “wrong” can be quantified in terms of how “unnecessarily surprised” it is expected to make him. A picture showing scratches on the readable surface of a CD-R.

Using a statistical description for data, information theory quantifies the number of bits needed to describe the data, which is the information entropy of the source. However, these theorems only hold in the situation where one transmitting user wishes to communicate to one receiving user. These terms are well studied in their own right outside information theory. For stationary sources, these two expressions give the same result. It is common in information theory to speak of the “rate” or “entropy” of a language. This is appropriate, for example, when the source of information is English prose. Consider the communications process over a discrete channel.

The possible channel outputs are 0, 1, and a third symbol ‘e’ called an erasure. The erasure represents complete loss of information about an input bit. Information theory leads us to believe it is much more difficult to keep secrets than it might first appear. The security of all such methods currently comes from the assumption that no known attack can break them in a practical amount of time. In other words, an eavesdropper would not be able to improve his or her guess of the plaintext by gaining knowledge of the ciphertext but not of the key. Soviet Union due to their improper reuse of key material.
