Figure 3.1: Generic stream cipher. We must assunie that Trudy, the cryptanalyst, knows (or can guess) some of the plaintext. For a stream cipher, known plaintext and the corresponding ciphertext immediately enables Trudy to recover part of the keystream. If Trudy can recover more of the keystream from such a captured segment: then the stream cipher is insecure. Therefore, the security of a stream cipher depends on properties of the generated keystream. But what properties should a keystreani ideally satisfy The keystream needs to be random, but there are many definitions of randomness, and many of these random sequences would be poor keystreams. For example, a common method for generating pseudo-random sequences is to employ a linear congruential generator (LCG). The output from these generators satisfy many statistical properties that make them excellent random sources for a variety of applications (for exaniple, simulations). The bits generated by an LCG could be used as a keystream, with the seed value acting as the key. However, an LCG would make a very poor stream cipher, since given a sniall section of the keystreani it is not difficult to determine the entire sequence [9]. This is exactly what we must avoid with a stream cipher keystream. In other words, statistical randomness is insufficient to ensure the security of a keyst rcarn. The crucial property required of a keystream sequence is that it be unpredictable, or cr gptop-aphically strong. Intuitively, it is clear what we mean by unpredictable, but there is no entirely satisfactory technical definition. We discuss this problem briefly in the ncxt section. In this chapter we first discuss linear feedback shift registers (LFSRs), which are often used as building blocks for stream ciphers. We also consider correlation attacks against a particular class of LFSR-based stream cipher.

Format is arguably the most important 2.14 A Start-up Image menu choice of the item on the Set-up menu. It is always G11 a good idea to format your SD cards in the camera they will be used in before each shooting session. Be sure that any images on the card are backed up to a storage device before formatting, however. From the Format menu you can perform either a regular format or a low-level (or deep) format. Low-level formatting rebuilds the entire le structure of the memory card and marks off any bad sectors. When you select Format from the Set-up menu, the Format options appear on the LCD. While low-level formatting takes a little longer to perform than regular formatting, you should do a low-level format every once in a while to keep your cards performing their best.

Results for three or more events simplify considerably if the events are mutually exclusive. In general, a collection of events, E1, E2, p , Ek , is said to be mutually exclusive if there is no overlap among any of them. The Venn diagram for several mutually exclusive events is shown in Fig. 2-11. By generalizing the reasoning for the union of two events, the following result can be obtained:

The ciphertext is read from the columns in alphabetical order (as determined by the keyword), so that, in this example, the ciphertext is ROUPSXCTFYIN. Is it possible to conduct a ciphertext-only attack on a keyword columnar transposition cipher It is certainly not as straightforward as attacking a non-keyword columnar cipher. Suppose we obtain the ciphertext

A collection of events, E1, E2, p , Ek, is said to be mutually exclusive if for all pairs, Ei Ej For a collection of mutually exclusive events, P1E1 E2 p Ek 2 P1E1 2 P1E2 2 p P1Ek 2 (2-4)

EXAMPLE 2-15

A simple example of mutually exclusive events will be used quite frequently. Let X denote the pH of a sample. Consider the event that X is greater than 6.5 but less than or equal to 7.8. This

which we believe was encrypted using a keyword columnar transposition. Our goal is to recover the key and the plaintext. First, note that there are 45 letters in the ciphertext. Assuming the array is not a single column or row, the array could have any of the following dimensions: 9 x 5. 5 x 9. 15 x 3 or 3 x 15. Suppose that we first try a 9 x 5 array. Then we have the ciphertext array in Table 1.1. We focus our attention on the top row of the array in Table 1.1. If we permute the columns as shown in Table 1.2, we see the word GIVE in the first row and we see words or partial words in the other rows. Therefore, we have almost certainly recovered the key. This method is somewhat ad hoc, but the process could be automated, provided we can automatically recognize likely plaintexts. In this example, we have recovered the encryption key 24013 and the plaintext is

probability is the sum of any collection of mutually exclusive events with union equal to the same range for X. One example is P16.5 X 7.82 P16.5 X 7.02 P17.0 X 7.52 P17.5 X 7.82
